FPL GROUP, INC.

Common Stock



        FPL Group, Inc. has entered into a distribution agency agreement with Credit Suisse Securities (USA) LLC, which is referred to as the "sales agent," relating to shares of common stock of FPL Group, par value $.01 per share, offered by this prospectus supplement and the accompanying prospectus. In accordance with the terms of the distribution agency agreement, FPL Group may offer and sell shares of the common stock offered hereby having an aggregate offering price of up to $334,719,000 from time to time through the sales agent. Sales of the shares, if any, will be made by means of ordinary brokers' transactions on the New York Stock Exchange at market prices, in block transactions or as otherwise agreed with the sales agent. FPL Group will pay the sales agent a commission equal to 0.75% of the gross sales price per share of shares sold through it as agent under the distribution agency agreement.

        Under the terms of the distribution agency agreement, FPL Group also may sell some or all of the shares of common stock to Credit Suisse as principal for its own account at a price agreed upon at the time of sale. If FPL Group sells shares to Credit Suisse as principal, FPL Group will enter into a separate terms agreement setting forth the terms of such transaction, and FPL Group will describe the agreement in a separate prospectus supplement or pricing supplement.

        The sales agent is not required to sell any specific number or dollar amount of shares of the common stock, but, subject to the terms and conditions of the distribution agency agreement and unless otherwise agreed by the sales agent and FPL Group, the sales agent will use its reasonable efforts to sell the shares offered as FPL Group's agent. There is no arrangement for shares to be received in an escrow, trust or similar arrangement. The offering of common stock pursuant to the distribution agency agreement will terminate upon the earlier of (1) the sale of all shares of common stock subject to the distribution agency agreement or (2) the termination of the distribution agency agreement by FPL Group or the sales agent.

        The common stock of FPL Group is listed on the New York Stock Exchange and trades under the symbol "FPL." On August 3, 2009, the last reported sale price of the common stock on the New York Stock Exchange was $57.01 per share.

        Investing in the common stock of FPL Group involves risks. See "Risk Factors" beginning on page S-3 of this prospectus supplement to read about some of the factors you should consider before making an investment in the common stock.

        Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

RISK FACTORS

        Investing in FPL Group's common stock involves risks. Before purchasing the common stock, you should carefully consider the following risk factors together with the risk factors and other information provided or incorporated by reference in this prospectus supplement and in the accompanying prospectus. FPL Group's business, financial condition or results of operations and the market price of the common stock could be materially adversely affected by any of these risks.

FPL Group's stock price has fluctuated over a wide range, and could fluctuate significantly in the future, as a result of FPL Group's operating performance, conditions in the electric utility industry and stock market conditions generally.

        The market price of the common stock has been, and may continue to be, subject to significant fluctuations due to factors relating to FPL Group's operating performance and conditions in the electric utility industry, including the factors discussed in the "Risk Factors" section of the accompanying prospectus and in the information incorporated by reference. In addition, the stock market in recent years has experienced extreme price and volume fluctuations, which have become more pronounced as a result of the recent global financial crisis. This volatility has had a significant impact on the market price of securities issued by many companies, including FPL Group and other energy services companies. The changes in the market prices of securities frequently appear to occur without regard to the financial results of these companies. Accordingly, the market price of the common stock could fluctuate based upon factors that are not directly related to FPL Group's operating performance, and these fluctuations could materially reduce FPL Group's stock price.

FPL Group's ability to continue to pay dividends on the common stock is subject to the risks affecting its business and to contractual restrictions that may limit its dividend-paying ability in specified circumstances.

        FPL Group is a holding company that conducts substantially all of its operations through its subsidiaries. The ability of FPL Group to pay dividends on the common stock is currently subject to, and in the future may be limited by:

        Florida Power & Light Company is subject to the terms of its Mortgage and Deed of Trust dated as of January 1, 1944, with Deutsche Bank Trust Company Americas (formerly known as Bankers Trust Company), as Trustee, as amended and supplemented from time to time, which we refer to as the "Mortgage," that secures its obligations under outstanding first mortgage bonds issued by it from time to time. In specified circumstances, the terms of the Mortgage could restrict the ability of Florida Power & Light Company to pay dividends and make other distributions to FPL Group. As of the date of this prospectus supplement, Florida Power & Light Company's ability to pay dividends to FPL Group was not restricted by the terms of the Mortgage.

        Other contractual restrictions on the dividend-paying ability of FPL Group or its subsidiaries are contained in outstanding financing arrangements, and may be included in future financing arrangements. FPL Group has issued equity units. In accordance with the terms of the equity units, FPL Group has the right, from time to time, to defer the payment of contract adjustment payments on the purchase contracts that form a part of the equity units to a date no later than the purchase contract settlement date. In the event that FPL Group exercises its right to defer the payment of contract

S-3



adjustment payments, then, until the deferred contract adjustment payments have been paid, FPL Group would not be able, with limited exceptions, to pay dividends on the common stock. FPL Group Capital has issued junior subordinated debentures that are guaranteed by FPL Group. FPL Group Capital has the right, from time to time, to defer the payment of interest on its outstanding junior subordinated debentures for a deferral period of up to 20 consecutive quarters, in the case of one series of such securities, and on one or more occasions for up to ten consecutive years, in the case of other series of such securities. FPL Group, Florida Power & Light Company or FPL Group Capital may issue, from time to time, additional equity units, junior subordinated debentures or other securities that (1) provide them with rights to defer the payment of interest or other payments and (2) contain dividend restrictions in the event of the exercise of such rights. In the event that FPL Group or FPL Group Capital were to exercise any right to defer interest or other payments on currently outstanding or future series of equity units, junior subordinated debentures or other securities, or if there were to occur certain payment defaults on those securities, FPL Group would not be able, with limited exceptions, to pay dividends on the common stock during the periods in which such payments were deferred or such payment defaults continued. In the event that Florida Power & Light Company were to exercise any such right to defer the payment of interest or other payments, it would not be able, with limited exceptions, to pay dividends to FPL Group or any other holder of its common stock or preferred stock during the periods in which such payments were deferred. FPL Group, FPL Group Capital and Florida Power & Light Company also might issue other securities in the future containing similar or other restrictions on FPL Group's ability to pay dividends on the common stock and on Florida Power & Light Company's ability to pay dividends to any holder of its common stock or preferred stock, including FPL Group.

        In addition, the right of the holders of FPL Group common stock to receive dividends might become subject to the preferential dividend, redemption, sinking fund or other rights of the holders of any series of FPL Group preferred stock that may be issued in the future, and the right of the holders of Florida Power & Light Company common stock or preferred stock, including FPL Group, to receive dividends might become subject to the preferential dividend, redemption, sinking fund or other rights of the holders of any series of Florida Power & Light Company preferred stock that may be issued in the future.

Provisions in FPL Group's organizational documents and the Florida Business Corporation Act could discourage takeover attempts that FPL Group's board of directors and management oppose even if holders of common stock might benefit from a change in control of FPL Group.

        Provisions in FPL Group's charter and bylaws and the Florida Business Corporation Act, or "Florida Act," may make it difficult and expensive for a third party to pursue a takeover attempt that FPL Group's board of directors and management oppose even if a change in control of FPL Group might be beneficial to the interests of holders of common stock. Among charter provisions that could have an anti-takeover effect are those that:

S-4


        The FPL Group bylaws contain some of the foregoing provisions contained in the charter. In addition, the bylaws contain provisions that limit to 16 directors the maximum number of authorized directors of FPL Group and that establish advance notice requirements for shareholders to nominate candidates for election as directors at any annual or special meeting of shareholders or to present any other business for consideration at an annual meeting.

        As a Florida corporation, FPL Group is subject to the Florida Act, which provides that an affiliated transaction with an interested shareholder generally must be approved by the affirmative vote of the holders of two-thirds of FPL Group's voting shares, other than the shares beneficially owned by the interested shareholder. The Florida Act also contains a control-share acquisition statute which provides that a person who acquires shares in an "issuing public corporation," as defined in the statute, in excess of certain specified thresholds generally will not have any voting rights with respect to such shares unless such voting rights are approved by the holders of a majority of the votes of each class of securities entitled to vote separately, excluding shares held or controlled by the acquiring person.

        The charter authorizes FPL Group's board of directors from time to time and without shareholder action to provide for the issuance of up to 100,000,000 shares of preferred stock in one or more series, and to fix the powers, preferences and rights of each such series. The rights and privileges of holders of common stock may be adversely affected by the powers, preferences and rights of holders of any series of preferred stock which FPL Group's board of directors may authorize for issuance from time to time. By authorizing the issuance of shares of preferred stock with particular voting, conversion or other rights and preferences, the board of directors could adversely affect the voting power of the holders of the common stock and could discourage unsolicited acquisition proposals or make it more difficult for a third party to gain control of FPL Group or otherwise could adversely affect the market price of the common stock.

S-5



USE OF PROCEEDS

        FPL Group intends to add the net proceeds from sales of the common stock, after deducting the sales agent's commission and other offering expenses, to its general funds. FPL Group estimates that offering expenses, exclusive of the sales agent's commission, will total approximately $600,000. FPL Group uses its general funds for corporate purposes, including to provide funds to its subsidiaries and to purchase securities issued by its subsidiaries. FPL Group's subsidiaries use funds provided to them by FPL Group for corporate purposes, including to repay short-term borrowings and to repay, redeem or repurchase outstanding long-term debt obligations.

        FPL Group and its subsidiaries will temporarily invest the net sale proceeds in short-term instruments pending their use for corporate purposes.

S-6



U.S. FEDERAL TAX CONSEQUENCES TO NON-U.S. HOLDERS

        The following is a general discussion of selected U.S. federal income and estate tax consequences of the acquisition, ownership and disposition of shares of the common stock by a non-U.S. holder that acquires such shares pursuant to this offering and holds the shares as a "capital asset" within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended, or the "Code." A capital asset for these purposes generally is property held for investment.

        As used in this discussion, the term "non-U.S. holder" means a beneficial owner of shares of common stock (other than a partnership) that is not, for U.S. federal income tax purposes:

        This discussion is based on provisions of the Code, existing and proposed U.S. Treasury regulations issued under the Code, and administrative and judicial interpretations, in each case, as of the date hereof. These authorities are subject to change, possibly with retroactive effect, or to different interpretations.

        This discussion does not address all aspects of U.S. federal income and estate taxes. Among other matters, this discussion does not consider:

If an entity treated as a partnership for U.S. federal income tax purposes holds shares of common stock, the tax treatment of a partner in the partnership generally will depend on the tax status of the partner and the activities of the partnership. A beneficial owner of shares of common stock who is a partner of a partnership that holds shares of common stock should consult such beneficial owner's own tax adviser.

S-7


        Prospective investors should seek advice from their own tax advisers concerning the United States federal, state, local and non-U.S. tax consequences of an investment in the shares of common stock based on their particular circumstances.

Dividends

        Any distributions on shares of common stock will constitute dividends for U.S. federal income tax purposes to the extent paid from FPL Group's current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent these distributions exceed FPL Group's current or accumulated earnings and profits, the excess will constitute a return of capital that is applied against, and will reduce, the holder's basis in the shares of common stock, but not below zero, and then will be treated as gain from the sale of shares of common stock.

        Dividends paid to a non-U.S. holder of shares of common stock that are not effectively connected with a non-U.S. holder's conduct of a U.S. trade or business generally will be subject to withholding of U.S. federal income tax at a 30% rate, or any lower rate specified by an applicable income tax treaty. To receive a reduced treaty rate, a non-U.S. holder must complete Form W-8BEN (or a substitute form) of the Internal Revenue Service, or "IRS," certify under penalty of perjury that such holder is eligible for benefits under the applicable treaty, and provide other additional information as required. The non-U.S. holder periodically must update the information on such forms. Special certification and other requirements apply to some non-U.S. holders that are pass-through entities rather than corporations or individuals. In addition, U.S. Treasury regulations provide special procedures for payments of dividends through specified intermediaries.

        If a non-U.S. holder satisfies specified certification and disclosure requirements, the following dividends are not subject to U.S. federal withholding tax:

The non-U.S. holder would be required to provide FPL Group with a properly executed IRS Form W-8ECI, for effectively connected income, or W-8BEN, for treaty benefits, or such successor form as the IRS designates. In such cases, dividends are subject to U.S. federal income tax on a net income basis at applicable graduated individual or corporate rates. In addition, a "branch profits tax" may be imposed at a 30% rate (or any lower rate that may be specified by an applicable income tax treaty) on dividends received by a foreign corporation that are effectively connected with the conduct of a trade or business in the United States.

        A non-U.S. holder that is eligible for a reduced rate of U.S. federal withholding tax under an income tax treaty may obtain a refund of any excess amounts withheld by filing with the IRS an appropriate claim for refund together with the required information.

Gain on Disposition of Shares of Common Stock

        A non-U.S. holder generally will not be subject to U.S. federal income or withholding tax with respect to gain recognized on a sale or other disposition of shares of common stock unless one of the following applies:

S-8


        In general, a corporation is a USRPHC if the fair market value of its "U.S. real property interests" equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests plus its other assets used or held for use in a trade or business. FPL Group believes that it is not currently, and will not become, a USRPHC for U.S. federal income tax purposes.

Federal Estate Tax

        Shares of common stock owned or treated as owned by an individual non-U.S. holder at the time of death will be included in the individual's gross estate for U.S. federal estate tax purposes, unless an applicable estate tax treaty provides otherwise, and, therefore, may be subject to U.S. federal estate tax. Estates of non-resident non-citizens are generally allowed a statutory credit, which has the effect of offsetting the U.S. federal estate tax imposed on the first $60,000 of the taxable estate. The test for whether an individual is a resident of the United States for U.S. federal estate tax purposes differs from the test used for U.S. federal income tax purposes. Some individuals, therefore, may be non-U.S. holders for U.S. federal income tax purposes, but not for U.S. federal estate tax purposes, or vice versa.

Information Reporting and Backup Withholding Tax

        Under U.S. Treasury regulations, FPL Group must report annually to the IRS and to each holder the gross amount of dividends paid to such holder and the tax withheld, if any, with respect to such dividends. The reporting requirements apply regardless of whether withholding was reduced or eliminated by an applicable income tax treaty. Copies of the information returns reporting such dividends and withholding also may be required under an applicable income tax treaty to be made available to the tax authorities in the country in which a non-U.S. holder resides.

        A holder of shares of common stock may be subject to backup withholding, currently at a rate of 28%, on payments of dividends if the holder fails to certify under penalties of perjury and in accordance with applicable U.S. Treasury regulations that such holder is a non-U.S. holder, or the payor has actual knowledge or reason to know that such holder is a U.S. person as defined under the Code.

        The payment of proceeds on the sale or other disposition of shares of common stock by or through a U.S. office of any U.S. or non-U.S. broker is subject to both backup withholding and information reporting unless the beneficial owner certifies under penalties of perjury that it is a non-U.S. holder (and the payor does not have actual knowledge or reason to know that such holder is

S-9



a U.S. person as defined under the Code), or such holder otherwise establishes an exemption. In general, backup withholding and information reporting will not apply to a payment of proceeds on a sale or other disposition of shares of common stock by or through a non-U.S. office of any U.S. or non-U.S. broker. If, however, the broker is, for U.S. federal income tax purposes

such payments will be subject to information reporting, but not backup withholding, unless the broker has documentary evidence in its records that the beneficial owner is a non-U.S. holder and other specified conditions are met or the beneficial owner otherwise establishes an exemption. In addition, backup withholding may apply in such cases unless specified certification requirements are satisfied or an exemption is otherwise established and the broker has no actual knowledge or reason to know that the holder is a U.S. person.

        Any amounts withheld under the backup withholding rules do not constitute a separate U.S. federal income tax. Rather, any such withheld amounts may be allowed as a refund or a credit against the holder's U.S. federal income tax liability, if any, if the required information is timely furnished to the IRS.

Recent Legislative Developments

        The Obama Administration recently announced international tax reform proposals that would limit the ability of non-U.S. holders to claim relief from U.S. withholding tax in respect of dividends paid on common stock, if such investors hold common stock through a non-U.S. intermediary that is not a "qualified intermediary." The Administration's proposals also would limit the ability of some non-U.S. entities to claim relief from U.S. withholding tax in respect of dividends paid to such non-U.S. entities unless the entities have provided documentation of their beneficial owners to the withholding agent. A third proposal would impose a 20% withholding tax on the gross proceeds of the sale of common stock effected through a non-U.S. intermediary that is not a qualified intermediary and that is not located in a jurisdiction with which the United States has a comprehensive income tax treaty having a satisfactory exchange of information provision. A non-U.S. holder generally would be permitted to claim a refund to the extent any tax withheld exceeded the investor's actual tax liability. The full details of these proposals have not yet been made public, although the Administration's summary of these proposals generally indicates that they are not intended to disrupt ordinary and customary market transactions. It is unclear whether, or in what form, these proposals may be enacted. Non-U.S. holders are encouraged to consult with their own tax advisers regarding the possible implications of the Administration's proposals on their decision to invest in FPL Group common stock.

        The foregoing discussion of U.S. federal tax consequences to non-U.S. holders is not tax advice and is not based on an opinion of counsel. Accordingly, each prospective non-U.S. holder of shares of the common stock should consult such holder's own tax adviser with respect to the United States federal, state, local and non-U.S. tax consequences of the ownership and disposition of shares of common stock.

S-10



PLAN OF DISTRIBUTION

        FPL Group has entered into a distribution agency agreement with Credit Suisse Securities (USA) LLC, which FPL Group refers to as the "sales agent," under which FPL Group may offer and sell shares of the common stock having an aggregate offering price of up to $400,000,000 from time to time through the sales agent. As of the date of this prospectus supplement, shares of common stock having an aggregate offering price of approximately $65,281,000 had been sold under the distribution agency agreement. Shares of common stock having an aggregate offering price of up to $334,719,000 may be offered and sold under the distribution agency agreement pursuant to this prospectus supplement and the accompanying prospectus.

        Sales of the shares, if any, under the distribution agency agreement will be made by means of ordinary brokers' transactions on the New York Stock Exchange at market prices, block transactions and such other transactions as agreed upon by FPL Group and the sales agent. The sales agent will not engage in any transactions that stabilize the price of the common stock.

        The sales agent will use its reasonable efforts to sell, as FPL Group's agent, the shares of common stock offered hereby on a daily basis or as otherwise agreed upon by FPL Group and such sales agent. FPL Group will designate the maximum amount of shares of common stock to be sold through the sales agent, on a daily basis or otherwise as FPL Group and such sales agent agree. Subject to the terms and conditions of the distribution agency agreement, the sales agent will use its reasonable efforts to sell, as sales agent and on behalf of FPL Group, all of the designated shares of common stock. FPL Group may instruct the sales agent not to sell shares of common stock if the sales cannot be effected at or above the price designated by FPL Group in any such instruction. FPL Group may suspend the offering of shares of common stock under the distribution agency agreement by notifying the sales agent. Similarly, the sales agent may suspend the offering of shares of common stock under the distribution agency agreement by notifying FPL Group of the suspension.

        FPL Group will pay the sales agent a commission equal to 0.75% of the gross sales price per share of shares sold through the sales agent as agent under the distribution agency agreement. FPL Group's net proceeds from the offering of shares hereunder will equal the gross proceeds, less the sum of the sales agent's commission, any expenses payable by FPL Group and any transaction fees imposed by any governmental or self-regulatory organization in connection with the sales. FPL Group has agreed to reimburse the sales agent for certain of its expenses in certain circumstances.

        Settlement for sales of common stock will occur on the third business day following the date on which any sales were made, in return for payment of the net proceeds to FPL Group. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

        Under the terms of the distribution agency agreement, FPL Group also may sell shares to Credit Suisse Securities (USA) LLC as principal for its own account at a price agreed upon at the time of sale. If FPL Group were to sell shares to Credit Suisse Securities (USA) LLC as principal, FPL Group would enter into a separate agreement setting forth the terms of such transaction and would describe this agreement in a separate prospectus supplement or pricing supplement.

        In connection with the sale of the common stock under this prospectus supplement, Credit Suisse Securities (USA) LLC may be deemed to be an "underwriter" within the meaning of the Securities Act of 1933, as amended, or the "Securities Act," and the compensation paid to it may be deemed to be underwriting commissions or discounts. FPL Group has agreed to provide indemnification and contribution to Credit Suisse Securities (USA) LLC against certain civil liabilities, including liabilities under the Securities Act.

RISK FACTORS

        Before purchasing the securities, investors should carefully consider the following risk factors together with the risk factors and other information incorporated by reference or provided in this prospectus or in a prospectus supplement in order to evaluate an investment in the securities.

FPL Group and FPL Group Capital are subject to complex laws and regulations and to changes in laws and regulations as well as changing governmental policies and regulatory actions. Florida Power & Light Company holds franchise agreements with local municipalities and counties, and must renegotiate expiring agreements. These factors may have a negative impact on the business and results of operations of FPL Group and FPL Group Capital.

        FPL Group and FPL Group Capital are subject to complex laws and regulations, and to changes in laws or regulations, with respect to, among other things, allowed rates of return, industry and rate structure, operation of nuclear power facilities, construction and operation of generation facilities, construction and operation of transmission and distribution facilities, acquisition, disposal, depreciation and amortization of assets and facilities, recovery of fuel and purchased power costs, decommissioning costs, return on common equity and equity ratio limits, transmission reliability and present or prospective wholesale and retail competition. This substantial and complex framework exposes FPL Group and FPL Group Capital to increased compliance costs and potentially significant monetary penalties for non-compliance. The Florida Public Service Commission has the authority to disallow recovery by Florida Power & Light Company of any and all costs that it considers excessive or imprudently incurred. The regulatory process generally restricts Florida Power & Light Company's ability to grow earnings and does not provide any assurance as to achievement of earnings levels.

        FPL Group and FPL Group Capital also are subject to extensive federal, state and local environmental statutes, rules and regulations, as well as the effect of changes in or additions to applicable statutes, rules and regulations that relate to, or in the future may relate to, for example, air quality, water quality, climate change, greenhouse gas emissions, carbon dioxide emissions, waste management, marine and wildlife mortality, natural resources, health, safety and renewable portfolio standards that could, among other things, restrict or limit the output of certain facilities or the use of certain fuels required for the production of electricity and/or require additional pollution control equipment and otherwise increase costs. There are significant capital, operating and other costs associated with compliance with these environmental statutes, rules and regulations, and those costs could be even more significant in the future.

        FPL Group and FPL Group Capital operate in a changing market environment influenced by various legislative and regulatory initiatives regarding regulation, deregulation or restructuring of the energy industry, including, for example, deregulation or restructuring of the production and sale of electricity, as well as increased focus on renewable and clean energy sources and reduction of carbon emissions. FPL Group and its subsidiaries will need to adapt to these changes and may face increasing costs and competitive pressure in doing so.

        FPL Group's results of operations could be affected by Florida Power & Light Company's ability to negotiate or renegotiate franchise agreements with municipalities and counties in Florida.

The operation and maintenance of power generation, transmission and distribution facilities involve significant risks that could adversely affect the results of operations and financial condition of FPL Group and FPL Group Capital.

        The operation and maintenance of power generation, transmission and distribution facilities involve many risks, including, for example, start up risks, breakdown or failure of equipment, transmission and distribution lines or pipelines, the inability to properly manage or mitigate known equipment defects throughout FPL Group's and FPL Group Capital's generation fleets and

2



transmission and distribution systems, use of new or unproven technology, the dependence on a specific fuel source, failures in the supply or transportation of fuel, the impact of unusual or adverse weather conditions (including natural disasters such as hurricanes, floods and droughts), and performance below expected or contracted levels of output or efficiency. This could result in lost revenues and/or increased expenses, including, for example, lost revenues due to prolonged outages and increased expenses due to monetary penalties or fines, replacement equipment costs or an obligation to purchase or generate replacement power at potentially higher prices to meet contractual obligations. Insurance, warranties or performance guarantees may not cover any or all of the lost revenues or increased expenses. Breakdown or failure of an operating facility of NextEra Energy Resources, LLC ("NextEra Energy Resources") may, for example, prevent the facility from performing under applicable power sales agreements which, in certain situations, could result in termination of the agreement or subject NextEra Energy Resources to incurring a liability for liquidated damages.

The operation and maintenance of nuclear facilities involves inherent risks, including environmental, health, regulatory, terrorism and financial risks, that could result in fines or the closure of nuclear units owned by Florida Power & Light Company or NextEra Energy Resources, and which may present potential exposures in excess of insurance coverage.

        Florida Power & Light Company and NextEra Energy Resources own, or hold undivided interests in, nuclear generation facilities in four states. These nuclear facilities are subject to environmental, health and financial risks such as on-site storage of spent nuclear fuel, the ability to dispose of spent nuclear fuel, the ability to maintain adequate reserves for decommissioning, potential liabilities arising out of the operation of these facilities, and the threat of a possible terrorist attack. Although Florida Power & Light Company and NextEra Energy Resources maintain decommissioning trusts and external insurance coverage to minimize the financial exposure to these risks, it is possible that the cost of decommissioning the facilities could exceed the amount available in the decommissioning trusts, and that liability and property damages could exceed the amount of insurance coverage.

        The Nuclear Regulatory Commission has broad authority to impose licensing and safety-related requirements for the construction and operation and maintenance of nuclear generation facilities. In the event of non-compliance, the Nuclear Regulatory Commission has the authority to impose fines or shut down a unit, or both, depending upon its assessment of the severity of the situation, until compliance is achieved. Nuclear Regulatory Commission orders or new regulations related to increased security measures and any future safety requirements promulgated by the Nuclear Regulatory Commission could require Florida Power & Light Company and NextEra Energy Resources to incur substantial operating and capital expenditures at their nuclear plants. In addition, if a serious nuclear incident were to occur at a Florida Power & Light Company or NextEra Energy Resources plant, it could result in substantial costs. A major incident at a nuclear facility anywhere in the world could cause the Nuclear Regulatory Commission to limit or prohibit the operation or licensing of any domestic nuclear unit.

        In addition, potential terrorist threats and increased public scrutiny of utilities could result in increased nuclear licensing or compliance costs which are difficult or impossible to predict.

The construction of, and capital improvements to, power generation and transmission facilities involve substantial risks. Should construction or capital improvement efforts be unsuccessful or delayed, the results of operations and financial condition of FPL Group and FPL Group Capital could be adversely affected.

        The ability of FPL Group and FPL Group Capital to complete construction of, and capital improvement projects for, their power generation and transmission facilities on schedule and within budget are contingent upon many variables that could delay completion, increase costs or otherwise adversely affect operational and financial results, including, for example, limitations related to

3



transmission interconnection issues, escalating costs for materials and labor and environmental compliance, delays with respect to permits and other approvals, and disputes involving third parties, and are subject to substantial risks. Should any such efforts be unsuccessful or delayed, FPL Group and FPL Group Capital could be subject to additional costs, termination payments under committed contracts, loss of tax credits and/or the write-off of their investment in the project or improvement.

The use of derivative contracts by FPL Group and FPL Group Capital in the normal course of business could result in financial losses or the payment of margin cash collateral that adversely impact the results of operations or cash flows of FPL Group and FPL Group Capital.

        FPL Group and FPL Group Capital use derivative instruments, such as swaps, options, futures and forwards, some of which are traded in the over-the-counter markets or on exchanges, to manage their commodity and financial market risks, and for FPL Group and FPL Group Capital to engage in trading and marketing activities. FPL Group and FPL Group Capital could recognize financial losses as a result of volatility in the market values of these derivative instruments, or if a counterparty fails to perform or make payments under these derivative instruments, and could suffer a reduction in operating cash flows as a result of the requirement to post margin cash collateral. In the absence of actively quoted market prices and pricing information from external sources, the valuation of these derivative instruments involves management's judgment or use of estimates. As a result, changes in the underlying assumptions or use of alternative valuation methods could affect the reported fair value of these derivative instruments. In addition, Florida Power & Light Company's use of such instruments could be subject to prudence challenges and, if found imprudent, cost recovery could be disallowed by the Florida Public Service Commission.

        FPL Group and FPL Group Capital provide full energy and capacity requirement services, which include load-following services and various ancillary services, primarily to distribution utilities to satisfy all or a portion of such utilities' power supply obligations to their customers. The supply costs for these transactions may be affected by a number of factors, such as weather conditions, fluctuating prices for energy and ancillary services, and the ability of the distribution utilities' customers to elect to receive service from competing suppliers, which could negatively affect FPL Group's and FPL Group Capital's results of operations from these transactions.

FPL Group's and FPL Group Capital's competitive energy business is subject to risks, many of which are beyond the control of FPL Group and FPL Group Capital, including, but not limited to, the efficient development and operation of generating assets, the successful and timely completion of project restructuring activities, the price and supply of fuel and equipment, transmission constraints, competition from other generators, including those using new sources of generation, excess generation capacity and demand for power, that may reduce the revenues and adversely impact the results of operations and financial condition of FPL Group and FPL Group Capital.

        There are various risks associated with FPL Group's and FPL Group Capital's competitive energy business. In addition to risks discussed elsewhere, risk factors specifically affecting NextEra Energy Resources' success in competitive wholesale markets include, for example, the ability to efficiently develop and operate generating assets, the successful and timely completion of project restructuring activities, maintenance of the qualifying facility status of certain projects, the price and supply of fuel (including transportation) and equipment, transmission constraints, the ability to utilize production tax credits, competition from other and new sources of generation, excess generation capacity and shifting demand for power. There can be significant volatility in market prices for fuel, electricity and renewable and other energy commodities, and there are other financial, counterparty and market risks that are beyond the control of NextEra Energy Resources. NextEra Energy Resources' inability or failure to effectively hedge its assets or positions against changes in commodity prices, interest rates, counterparty credit risk or other risk measures could significantly impair FPL Group's and FPL Group

4



Capital's future financial results. In keeping with industry trends, a portion of NextEra Energy Resources' power generation facilities operate wholly or partially without long-term power purchase agreements. As a result, power from these facilities is sold on the spot market or on a short-term contractual basis, which may increase the volatility of FPL Group's and FPL Group Capital's financial results. In addition, NextEra Energy Resources' business depends upon power transmission and natural gas transportation facilities owned and operated by others; if transmission or transportation is disrupted or capacity is inadequate or unavailable, NextEra Energy Resources' ability to sell and deliver its wholesale power or natural gas may be limited.

FPL Group's and FPL Group Capital's ability to successfully identify, complete and integrate acquisitions is subject to significant risks, including, but not limited to, the effect of increased competition for acquisitions resulting from the consolidation of the power industry.

        FPL Group and FPL Group Capital are likely to encounter significant competition for acquisition opportunities that may become available as a result of the consolidation of the power industry in general. In addition, FPL Group and FPL Group Capital may be unable to identify attractive acquisition opportunities at favorable prices and to complete and integrate them successfully and in a timely manner.

FPL Group and FPL Group Capital participate in markets that are often subject to uncertain economic conditions, which make it difficult to estimate growth, future income and expenditures.

        FPL Group and FPL Group Capital participate in markets that are susceptible to uncertain economic conditions, which complicate estimates of revenue growth. Because components of budgeting and forecasting are dependent upon estimates of revenue growth in the markets FPL Group and FPL Group Capital serve, the uncertainty makes estimates of future income and expenditures more difficult. As a result, FPL Group and FPL Group Capital may make significant investments and expenditures but never realize the anticipated benefits, which could adversely affect results of operations. The future direction of the overall economy also may have a significant effect on the overall performance and financial condition of FPL Group and FPL Group Capital.

Customer growth and customer usage in Florida Power & Light Company's service area affect FPL Group's results of operations.

        FPL Group's results of operations are affected by the growth in customer accounts in Florida Power & Light Company's service area and by customer usage. Customer growth can be affected by population growth. Customer growth and customer usage can be affected by economic factors in Florida and elsewhere, including, for example, job and income growth, housing starts and new home prices. Customer growth and customer usage directly influence the demand for electricity and the need for additional power generation and power delivery facilities at Florida Power & Light Company.

Weather affects FPL Group's and FPL Group Capital's results of operations, as can the impact of severe weather. Weather conditions directly influence the demand for electricity and natural gas, affect the price of energy commodities, and can affect the production of electricity at power generating facilities.

        FPL Group's and FPL Group Capital's results of operations are affected by changes in the weather. Weather conditions directly influence the demand for electricity and natural gas, affect the price of energy commodities, and can affect the production of electricity at power generating facilities, including, but not limited to, wind, solar and hydro-powered facilities. FPL Group's and FPL Group Capital's results of operations can be affected by the impact of severe weather which can be destructive, causing outages and/or property damage, may affect fuel supply, and could require

5



additional costs to be incurred. At Florida Power & Light Company, recovery of these costs is subject to Florida Public Service Commission approval.

Adverse capital and credit market conditions may adversely affect FPL Group's and FPL Group Capital's ability to meet liquidity needs, access capital and operate and grow their businesses, and increase the cost of capital. Disruptions, uncertainty or volatility in the financial markets can also adversely impact the results of operations and financial condition of FPL Group and FPL Group Capital, as well as exert downward pressure on the market price of FPL Group's common stock.

        Having access to the credit and capital markets, at a reasonable cost, is necessary for FPL Group, FPL Group Capital and Florida Power & Light Company to fund their operations, including their capital requirements. Those markets have provided FPL Group, FPL Group Capital and Florida Power & Light Company with the liquidity to operate and grow their businesses that is not otherwise provided from operating cash flows. Disruptions, uncertainty or volatility in those markets can increase FPL Group's, FPL Group Capital's and Florida Power & Light Company's cost of capital. If FPL Group, FPL Group Capital and Florida Power & Light Company are unable to access the credit and capital markets on terms that are reasonable, they may have to delay raising capital, issue shorter-term securities and/or bear an unfavorable cost of capital, which, in turn, could adversely impact their ability to grow their businesses, decrease earnings, significantly reduce financial flexibility and/or limit FPL Group's ability to sustain its current common stock dividend level.

        The market price and trading volume of FPL Group's common stock could be subject to significant fluctuations due to, among other things, general stock market conditions and changes in market sentiment regarding FPL Group and its subsidiaries' operations, business, growth prospects and financing strategies.

FPL Group's, FPL Group Capital's and Florida Power & Light Company's inability to maintain their current credit ratings may adversely affect FPL Group's and FPL Group Capital's liquidity, limit the ability of FPL Group, FPL Group Capital and Florida Power & Light Company to grow their businesses, and would likely increase interest costs.

        FPL Group, FPL Group Capital and Florida Power & Light Company rely on access to capital and credit markets as significant sources of liquidity for capital requirements not satisfied by operating cash flows. The inability of FPL Group, FPL Group Capital and Florida Power & Light Company to maintain their current credit ratings could affect their ability to raise capital or obtain credit on favorable terms, which, in turn, could impact FPL Group's, FPL Group Capital's and Florida Power & Light Company's ability to grow their businesses and would likely increase their interest costs.

FPL Group and FPL Group Capital are subject to credit and performance risk from third parties under supply and service contracts.

        FPL Group, FPL Group Capital and Florida Power & Light Company rely on contracts with vendors for the supply of equipment, materials, fuel and other goods and services required for the construction and operation of, and for capital improvements to, their facilities, as well as for business operations. If vendors fail to fulfill their contractual obligations, FPL Group, FPL Group Capital and Florida Power & Light Company may need to make arrangements with other suppliers, which could result in higher costs, untimely completion of power generation facilities and other projects, and/or a disruption to their operations.

6



FPL Group and FPL Group Capital are subject to costs and other potentially adverse effects of legal and regulatory proceedings, as well as regulatory compliance and changes in or additions to applicable tax laws, rates or policies, rates of inflation, accounting standards, securities laws, corporate governance requirements and labor and employment laws.

        FPL Group, FPL Group Capital and Florida Power & Light Company are subject to costs and other potentially adverse effects of legal and regulatory proceedings, settlements, investigations and claims, as well as regulatory compliance and the effect of new, or changes in, tax laws, rates or policies, rates of inflation, accounting standards, securities laws, corporate governance requirements and labor and employment laws.

        Florida Power & Light Company and NextEra Energy Resources, as owners and operators of bulk power transmission systems and/or critical assets within various regions throughout the United States, are subject to mandatory reliability standards promulgated by the North American Electric Reliability Corporation and enforced by the Federal Energy Regulatory Commission. These standards, which previously were being applied on a voluntary basis, became mandatory in June 2007. Noncompliance with these mandatory reliability standards could result in sanctions, including substantial monetary penalties, which likely would not be recoverable from customers.

Threats of terrorism and catastrophic events that could result from terrorism, cyber attacks, or individuals and/or groups attempting to disrupt FPL Group's and FPL Group Capital's business may impact the operations of FPL Group and FPL Group Capital in unpredictable ways.

        FPL Group and FPL Group Capital are subject to direct and indirect effects of terrorist threats and activities as well as cyber attacks and disruptive activities of individuals and/or groups. Infrastructure facilities and systems, including, for example, generation, transmission and distribution facilities, physical assets and information systems, in general, have been identified as potential targets. The effects of these threats and activities include, but are not limited to, the inability to generate, purchase or transmit power, the delay in development and construction of new generating facilities, the risk of a significant slowdown in growth or a decline in the U.S. economy, delay in economic recovery in the United States, and the increased cost and adequacy of security and insurance.

The ability of FPL Group and FPL Group Capital to obtain insurance and the terms of any available insurance coverage could be adversely affected by international, national, state or local events and company-specific events.

        FPL Group's, FPL Group Capital's and Florida Power & Light Company's ability to obtain insurance, and the cost of and coverage provided by such insurance, could be adversely affected by international, national, state or local events as well as company-specific events.

FPL Group and FPL Group Capital are subject to employee workforce factors that could adversely affect the businesses and financial condition of FPL Group and FPL Group Capital.

        FPL Group, FPL Group Capital and Florida Power & Light Company are subject to employee workforce factors, including, for example, loss or retirement of key executives, availability of qualified personnel, inflationary pressures on payroll and benefits costs and collective bargaining agreements with union employees and work stoppage that could adversely affect the businesses and financial condition of FPL Group and FPL Group Capital.

FORWARD-LOOKING STATEMENTS

        In connection with the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, FPL Group, FPL Group Capital and the Trust are herein filing cautionary statements identifying important factors that could cause FPL Group's and FPL Group Capital's actual results to differ materially from those projected in forward-looking statements (as such term is defined in the Private Securities Litigation Reform Act of 1995) made by or on behalf of FPL Group, FPL Group Capital and the Trust in this prospectus or any supplement to this prospectus, in presentations, in response to questions or otherwise. Any statements that express, or involve discussions as to, expectations, beliefs, plans, objectives, assumptions, future events or performance, climate change strategy or growth strategies (often, but not always, through the use of words or phrases such as "will," "will likely result," "are expected to," "will continue," "aim," "is anticipated," "believe," "could," "should," "would," "estimated," "may," "plan," "potential," "projection," "target," "outlook," "predict," and "intend" or words of similar meaning) are not statements of historical facts and may be forward-looking. Forward-looking statements involve estimates, assumptions and uncertainties. Accordingly, any such statements are qualified in their entirety by reference to, and are accompanied by, the specific factors discussed in "Risk Factors" herein and in FPL Group's reports that are incorporated herein by reference (in addition to any assumptions and other factors referred to specifically in connection with such forward-looking statements) that could have a significant impact on FPL Group's and FPL Group Capital's operations and financial results, and could cause FPL Group's or FPL Group Capital's actual results to

differ materially from those contained or implied in forward-looking statements made by or on behalf of FPL Group, FPL Group Capital or the Trust.

        Any forward-looking statement speaks only as of the date on which that statement is made, and neither FPL Group, FPL Group Capital nor the Trust undertakes any obligation to update any forward-looking statement to reflect events or circumstances, including unanticipated events, after the date on which that statement is made, unless otherwise required by law. New factors emerge from time to time and it is not possible for management to predict all of those factors, nor can it assess the impact of each of those factors on the business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statement.

        The issues and associated risks and uncertainties discussed in "Risk Factors" herein and in the reports that are incorporated herein by reference are not the only ones FPL Group or FPL Group Capital may face. Additional issues may arise or become material as the energy industry evolves.

The description is qualified in its entirety by reference to the provisions of FPL Group's Restated Articles of Incorporation, as amended ("FPL Group's Charter"), and Amended and Restated Bylaws, as currently in effect, the other documents described below, and applicable laws. Each of FPL Group's Charter and bylaws, as currently in effect, and the other documents described below has previously been filed with the SEC and they are exhibits to the registration statement of which this prospectus is a part and may be obtained as described under "Incorporation by Reference" on page 11 of this prospectus.

Authorized and Outstanding Capital Stock

        FPL Group's Charter authorizes it to issue 900,000,000 shares of capital stock, each with a par value of $.01, consisting of:

        As of June 30, 2009, there were 411,461,266 shares of common stock and no shares of preferred stock issued and outstanding. As of the same date, FPL Group's board of directors had not authorized for issuance any series of preferred stock.

Common Stock Terms

        Voting Rights.    In general, each holder of common stock is entitled to one vote for each share held by such holder on all matters submitted to a vote of holders of the common stock, including the election of directors. Each holder of common stock is entitled to attend all special and annual meetings of FPL Group's shareholders. The holders of common stock do not have cumulative voting rights. Unless otherwise provided by FPL Group's Charter or bylaws or applicable law, the affirmative vote of the holders of a majority of the total number of shares represented at a meeting and entitled to vote on a matter (including the election of directors) is required for shareholder action on that matter.

        Dividend Rights.    The holders of common stock are entitled to participate on an equal per-share basis in any dividends declared on the common stock by FPL Group's board of directors out of funds legally available for dividend payments.

        The declaration and payment of dividends on the common stock is within the sole discretion of FPL Group's board of directors. FPL Group's Charter does not limit the dividends that may be paid on the common stock.

        The ability of FPL Group to pay dividends on the common stock is currently subject to, and in the future may be limited by:

        Florida Power & Light Company is subject to the terms of its Mortgage and Deed of Trust dated as of January 1, 1944, with Deutsche Bank Trust Company Americas (formerly known as Bankers Trust Company), as Trustee, as amended and supplemented from time to time (the "Mortgage"), that secures its obligations under outstanding first mortgage bonds issued by it from time to time. In specified circumstances, the terms of the Mortgage could restrict the ability of Florida Power & Light Company

13



to pay dividends and make other distributions to FPL Group. As of the date of this prospectus, Florida Power & Light Company's ability to pay dividends to FPL Group was not restricted by the terms of the Mortgage.

        Other contractual restrictions on the dividend-paying ability of FPL Group or its subsidiaries are contained in outstanding financing arrangements, and may be included in future financing arrangements. FPL Group has issued equity units. In accordance with the terms of the equity units, FPL Group has the right, from time to time, to defer the payment of contract adjustment payments on the purchase contracts that form a part of the equity units to a date no later than the purchase contract settlement date. In the event that FPL Group exercises its right to defer the payment of contract adjustment payments, then, until the deferred contract adjustment payments have been paid, FPL Group would not be able, with limited exceptions, to pay dividends on the common stock. FPL Group Capital has issued junior subordinated debentures that are guaranteed by FPL Group. FPL Group Capital has the right, from time to time, to defer the payment of interest on its outstanding junior subordinated debentures for a deferral period of up to 20 consecutive quarters, in the case of one series of such securities, and on one or more occasions for up to ten consecutive years, in the case of other series of such securities. FPL Group, Florida Power & Light Company or FPL Group Capital may issue, from time to time, additional equity units, junior subordinated debentures or other securities that (i) provide them with rights to defer the payment of interest or other payments and (ii) contain dividend restrictions in the event of the exercise of such rights. In the event that FPL Group or FPL Group Capital were to exercise any right to defer interest or other payments on currently outstanding or future series of equity units, junior subordinated debentures or other securities, or if there were to occur certain payment defaults on those securities, FPL Group would not be able, with limited exceptions, to pay dividends on the common stock during the periods in which such payments were deferred or such payment defaults continued. In the event that Florida Power & Light Company were to exercise any such right to defer the payment of interest or other payments, it would not be able, with limited exceptions, to pay dividends to FPL Group or any other holder of its common stock or preferred stock during the periods in which such payments were deferred. In addition, FPL Group, FPL Group Capital and Florida Power & Light Company might issue other securities in the future containing similar or other restrictions on FPL Group's ability to pay dividends on the common stock and on Florida Power & Light Company's ability to pay dividends to any holder of its common stock or preferred stock, including FPL Group.

        In addition, the right of the holders of FPL Group's common stock to receive dividends might become subject to the preferential dividend, redemption, sinking fund or other rights of the holders of any series of FPL Group preferred stock that may be issued in the future, and the right of the holders of Florida Power & Light Company common stock or preferred stock, including FPL Group, to receive dividends might become subject to the preferential dividend, redemption, sinking fund or other rights of the holders of any series of Florida Power & Light Company preferred stock that may be issued in the future.

        Liquidation Rights.    If there is a liquidation, dissolution or winding up of FPL Group, the holders of common stock are entitled to share equally and ratably in any assets remaining after FPL Group has paid, or provided for the payment of, all of its debts and other liabilities, and after FPL Group has paid, or provided for the payment of, any preferential amounts payable to the holders of any outstanding preferred stock.

        Other Rights.    The holders of common stock do not have any preemptive, subscription, conversion or sinking fund rights. The common stock is not subject to redemption.

Anti-Takeover Effects of Provisions in FPL Group's Charter and Bylaws

        FPL Group's Charter and bylaws contain provisions that may make it difficult and expensive for a third party to pursue a takeover attempt that FPL Group's board of directors and management oppose even if a change in control of FPL Group might be beneficial to the interests of holders of common stock.

        FPL Group's Charter Provisions.    Among FPL Group's Charter provisions that could have an anti-takeover effect are those that:

        FPL Group's Charter defines the term "interested shareholder" to include a security holder who is the direct or indirect beneficial owner of 10% or more of the voting power of the outstanding shares of voting stock, and the term "continuing director" to include any director who is not an affiliate of an interested shareholder. The foregoing provisions may discriminate against a security holder who becomes an interested shareholder by reason of its beneficial ownership of the specified amount of common or other voting stock.

        The term "business combination" is defined in FPL Group's Charter to include the following transactions:

15


        For purposes of the foregoing "business combination" provisions, FPL Group's Charter defines the term "subsidiary" as any corporation of which FPL Group owns, directly or indirectly, a majority of any class of equity securities.

        The foregoing shareholder approval requirements are in addition to those required by law, including the provisions of the Florida Business Corporation Act described below.

        Bylaw Provisions.    The FPL Group bylaws contain some of the foregoing provisions contained in FPL Group's Charter. The bylaws also contain a provision limiting to 16 directors the maximum number of authorized directors of FPL Group. In addition, the bylaws contain provisions that establish advance notice requirements for shareholders to nominate candidates for election as directors at any annual or special meeting of shareholders or to present any other business for consideration at any annual meeting of shareholders. These provisions generally require a shareholder to submit in writing to FPL Group's secretary any nomination of a candidate for election to the board of directors or any other proposal for consideration at any annual meeting not earlier than 120 days or later than 90 days before the first anniversary of the preceding year's annual meeting. The bylaws also require a shareholder to submit in writing to FPL Group's secretary any nomination of a candidate for election to the board of directors for consideration at any special meeting not earlier than 120 days before such special meeting and not after the later of 90 days before such special meeting or the tenth day following the day of the first public announcement of the date of the special meeting and of the fact that directors are to be elected at the meeting. For the shareholder's notice to be in proper form, it must include all of the information specified in the bylaws.

Restrictions on Affiliated and Control Share Transactions Under Florida Act

        Affiliated Transactions.    As a Florida corporation, FPL Group is subject to the Florida Business Corporation Act, or "Florida Act," which provides that an "affiliated transaction" of a Florida corporation with an "interested shareholder," as those terms are defined in the statute, generally must be approved by the affirmative vote of the holders of two-thirds of the outstanding voting shares, other than the shares beneficially owned by the interested shareholder. The Florida Act defines an "interested shareholder" as any person who is the beneficial owner of more than 10% of the

16


outstanding voting shares of the corporation. The affiliated transactions covered by the Florida Act include, with specified exceptions:

        The foregoing transactions generally also include transactions involving any affiliate of the interested shareholder and involving or affecting any direct or indirect majority-owned subsidiary of the corporation.

        The two-thirds approval requirement does not apply if, among other things, subject to specified qualifications:

        The foregoing restrictions do not apply if the corporation's original articles of incorporation or an amendment to its articles of incorporation or bylaws approved by the affirmative vote of the holders of a majority of the outstanding shares of voting stock of the corporation (other than shares held by the interested shareholder) contain a provision expressly electing for the corporation not to be governed by the restrictions. FPL Group's Charter and bylaws do not contain such a provision.

        Control-Share Acquisitions.    The Florida Act also contains a control-share acquisition statute which provides that a person who acquires shares in an "issuing public corporation," as defined in the statute, in excess of certain specified thresholds generally will not have any voting rights with respect to such shares unless such voting rights are approved by the holders of a majority of the votes of each class of securities entitled to vote separately, excluding shares held or controlled by the acquiring person. The thresholds specified in the Florida Act are the acquisition of a number of shares representing:

17


        The statute does not apply if, among other things, the acquisition:

        The statute also does not apply to an acquisition of shares of a corporation in excess of a specified threshold if, before the acquisition, the corporation's articles of incorporation or bylaws provide that the corporation will not be governed by the statute. The statute also permits a corporation to adopt a provision in its articles of incorporation or bylaws providing for the redemption of the acquired shares by the corporation in specified circumstances. FPL Group's Charter and bylaws do not contain such provisions.

Preferred Stock

        FPL Group's Charter authorizes FPL Group's board of directors from time to time and without shareholder action to provide for the issuance of up to 100,000,000 shares of preferred stock in one or more series, and to determine the designations, preferences, limitations and relative or other rights of any such series, including voting rights, dividend rights, liquidation preferences, sinking fund provisions, conversion privileges and redemption rights. FPL Group's board of directors has broad discretion with respect to the creation and issuance of any series of preferred stock without shareholder approval, subject to any applicable rights of holders of any shares of preferred stock outstanding at any time. The rights and privileges of holders of common stock may be adversely affected by the rights, privileges and preferences of holders of shares of any series of preferred stock which FPL Group's board of directors may authorize for issuance from time to time. Among other things, by authorizing the issuance of shares of preferred stock with particular voting, conversion or other rights, the board of directors could adversely affect the voting power of the holders of the common stock and could discourage any attempt to effect a change in control of FPL Group, even if such a transaction would be beneficial to the interests of holders of the common stock. See the description of FPL Group's Preferred Stock in "Description of FPL Group Preferred Stock" in this prospectus.

Indemnification

        Florida law generally provides that a Florida corporation, such as FPL Group, may indemnify its directors, officers, employees and agents against liabilities and expenses they may incur. Florida law also limits the liability of directors to FPL Group and other persons. FPL Group's bylaws contain provisions requiring FPL Group to indemnify its directors, officers, employees and agents under specified conditions. In addition, FPL Group carries insurance permitted by the laws of Florida on behalf of its directors, officers, employees and agents.

Transfer Agent and Register

        The transfer agent and registrar for the common stock is Computershare Investor Services, LLC.

Listing

        The common stock is listed on the New York Stock Exchange and trades under the symbol "FPL."

DESCRIPTION OF FPL GROUP GUARANTEE OF FPL GROUP CAPITAL PREFERRED STOCK

        The following statements describing FPL Group's guarantee of FPL Group Capital's preferred stock are not intended to be a complete description. For additional information, please see FPL Group's guarantee agreement relating to FPL Group Capital's preferred stock. You should read this summary together with the guarantee agreement for a complete understanding of all the provisions. Please also see the Mortgage, which contains restrictions which may in certain instances limit the ability of Florida Power & Light Company to pay dividends to FPL Group. Each of these documents has previously been filed with the SEC and each is an exhibit to the registration statement filed with the SEC of which this prospectus is a part.

        FPL Group will fully, unconditionally and irrevocably guarantee the payment of accumulated and unpaid dividends, and payments due on liquidation or redemption, as and when due, regardless of any defense, right of set-off or counterclaim that FPL Group Capital may have or assert. FPL Group's guarantee of FPL Group Capital's preferred stock will be an unsecured obligation of FPL Group and will rank (1) subordinate and junior in right of payment to all other liabilities of FPL Group (except those made pari passu or subordinate by their terms), (2) equal in right of payment with the most senior preferred or preference stock that may be issued by FPL Group and with any other guarantee that may be entered into by FPL Group in respect of any preferred or preference stock of any affiliate of FPL Group, and (3) senior to FPL Group's common stock. A prospectus supplement will describe the terms of FPL Group's guarantee of FPL Group Capital's preferred stock. The description will not necessarily be complete, and reference will be made to the preferred stock guarantee agreement.

        While FPL Group is a holding company that derives substantially all of its income from its operating subsidiaries, FPL Group's subsidiaries are separate and distinct legal entities and have no obligation to make any payments under the FPL Group guarantee of FPL Group Capital preferred stock or to make any funds available for such payment. Therefore, the FPL Group guarantee of FPL Group Capital preferred stock will effectively be subordinated to all indebtedness and other liabilities, including trade payables, debt and preferred stock, incurred or issued by FPL Group's subsidiaries. In addition to trade liabilities, many of FPL Group's operating subsidiaries incur debt in order to finance their business activities. All of this indebtedness will effectively be senior to the FPL Group guarantee of FPL Group Capital preferred stock. FPL Group's guarantee of FPL Group Capital preferred stock does not place any limit on the amount of liabilities, including debt or preferred stock, that FPL Group's subsidiaries may issue, guarantee or otherwise incur. See "Description of FPL Group Common Stock—Common Stock Terms—Dividend Rights" for a description of contractual restrictions on the dividend-paying ability of some of FPL Group's subsidiaries.

DESCRIPTION OF FPL GROUP CAPITAL SENIOR DEBT SECURITIES

        General.    FPL Group Capital may issue its debt securities (other than the FPL Group Capital Junior Subordinated Debentures (as defined below under "Description of FPL Group and FPL Group Capital Junior Subordinated Debentures and FPL Group Subordinated Guarantee")), in one or more series, under an Indenture, dated as of June 1, 1999, between FPL Group Capital and The Bank of New York Mellon, as trustee. This Indenture, as it may be amended and supplemented from time to time, is referred to in this prospectus as the "Indenture." The Bank of New York Mellon, as trustee under the Indenture, is referred to in this prospectus as the "Indenture Trustee." These debt securities are referred to in this prospectus as the "Offered Senior Debt Securities."

        The Indenture provides for the issuance from time to time of debentures, notes or other senior debt by FPL Group Capital in an unlimited amount. The Offered Senior Debt Securities and all other debentures, notes or other debt of FPL Group Capital issued under the Indenture are collectively referred to in this prospectus as the "Senior Debt Securities."

        This section briefly summarizes some of the terms of the Offered Senior Debt Securities and some of the provisions of the Indenture. This summary does not contain a complete description of the Offered Senior Debt Securities or the Indenture. You should read this summary together with the Indenture and the officer's certificates or other documents creating the Offered Senior Debt Securities for a complete understanding of all the provisions and for the definitions of some terms used in this summary. The Indenture, the form of officer's certificate that may be used to create a series of Offered Senior Debt Securities and a form of Offered Senior Debt Securities have previously been filed with the SEC, and are exhibits to the registration statement filed with the SEC of which this prospectus is a part. In addition, the Indenture is qualified under the Trust Indenture Act of 1939 and is therefore subject to the provisions of the Trust Indenture Act of 1939. You should read the Trust Indenture Act of 1939 for a complete understanding of its provisions.

        All Offered Senior Debt Securities of one series need not be issued at the same time, and a series may be re-opened for issuances of additional Offered Senior Debt Securities of such series. This means that FPL Group Capital may from time to time, without notice to, or the consent of the existing holders of the Offered Senior Debt Securities of a particular series, create and issue additional Offered Senior Debt Securities of such series. Such additional Offered Senior Debt Securities will have the same terms as the previously-issued Offered Senior Debt Securities of such series in all respects (except for the payment of interest accruing prior to the issue date of the additional Offered Senior Debt Securities or except for the first payments of interest following the issue date of the additional Offered Senior Debt Securities) so that the additional Offered Senior Debt Securities may be consolidated and form a single series with the previously-issued Offered Senior Debt Securities of such series.

        Each series of Offered Senior Debt Securities may have different terms. FPL Group Capital will include some or all of the following information about a specific series of Offered Senior Debt Securities in the particular prospectus supplement relating to that specific series of Offered Senior Debt Securities:

25


26


        FPL Group Capital may sell Offered Senior Debt Securities at a discount below their principal amount. Some of the important United States federal income tax considerations applicable to Offered Senior Debt Securities sold at a discount below their principal amount may be discussed in the related prospectus supplement. In addition, some of the important United States federal income tax or other considerations applicable to any Offered Senior Debt Securities that are denominated in a currency other than U.S. dollars may be discussed in the related prospectus supplement.

        Except as otherwise stated in the related prospectus supplement, the covenants in the Indenture would not give registered owners of Offered Senior Debt Securities protection in the event of a highly-leveraged transaction involving FPL Group Capital or FPL Group.

        Security and Ranking.    The Offered Senior Debt Securities will be unsecured obligations of FPL Group Capital. The Indenture does not limit FPL Group Capital's ability to provide security with respect to other Senior Debt Securities. All Senior Debt Securities issued under the Indenture will rank equally and ratably with all other Senior Debt Securities issued under the Indenture, except to the extent that FPL Group Capital elects to provide security with respect to any Senior Debt Security (other than the Offered Senior Debt Securities) without providing that security to all outstanding Senior Debt Securities in accordance with the Indenture. The Offered Senior Debt Securities will rank senior to FPL Group Capital's Junior Subordinated Debentures. The Indenture does not limit FPL Group Capital's ability to issue other unsecured debt.

        While FPL Group Capital is a holding company that derives substantially all of its income from its operating subsidiaries, FPL Group Capital's subsidiaries are separate and distinct legal entities and have no obligation to make any payments on the Senior Debt Securities or to make any funds available for such payment. Therefore, the Senior Debt Securities will effectively be subordinated to all indebtedness and other liabilities, including trade payables, debt and preferred stock, incurred or issued by FPL Group Capital's subsidiaries. In addition to trade liabilities, many of FPL Group Capital's operating subsidiaries incur debt in order to finance their business activities. All of this indebtedness will effectively be senior to the Senior Debt Securities. The Indenture does not place any limit on the amounts of liabilities, including debt or preferred stock, that FPL Group Capital's subsidiaries may issue, guarantee or otherwise incur.

        Payment and Paying Agents.    Except as stated in the related prospectus supplement, on each interest payment date FPL Group Capital will pay interest on each Offered Senior Debt Security to the person in whose name that Offered Senior Debt Security is registered as of the close of business on the

record date relating to that interest payment date. However, on the date that the Offered Senior Debt Securities mature, FPL Group Capital will pay the interest to the person to whom it pays the principal. Also, if FPL Group Capital has defaulted in the payment of interest on any Offered Senior Debt Security, it may pay that defaulted interest to the registered owner of that Offered Senior Debt Security:

        Unless otherwise stated in the related prospectus supplement, the principal, premium, if any, and interest on the Offered Senior Debt Securities at maturity will be payable when such Offered Senior Debt Securities are presented at the main corporate trust office of The Bank of New York Mellon, as paying agent, in The City of New York. FPL Group Capital may change the place of payment on the Offered Senior Debt Securities, appoint one or more additional paying agents, including itself, and remove any paying agent. (Indenture, Section 602).

        Transfer and Exchange.    Unless otherwise stated in the related prospectus supplement, Offered Senior Debt Securities may be transferred or exchanged at the main corporate trust office of The Bank of New York Mellon, as security registrar, in The City of New York. FPL Group Capital may change the place for transfer and exchange of the Offered Senior Debt Securities and may designate one or more additional places for that transfer and exchange.

        Except as otherwise stated in the related prospectus supplement, there will be no service charge for any transfer or exchange of the Offered Senior Debt Securities. However, FPL Group Capital may require payment of any tax or other governmental charge in connection with any transfer or exchange of the Offered Senior Debt Securities.

        FPL Group Capital will not be required to transfer or exchange any Offered Senior Debt Security selected for redemption. Also, FPL Group Capital will not be required to transfer or exchange any Offered Senior Debt Security during a period of 15 days before selection of Offered Senior Debt Securities to be redeemed. (Indenture, Section 305).

        Defeasance.    FPL Group Capital may, at any time, elect to have all of its obligations discharged with respect to all or a portion of any Senior Debt Securities. To do so, FPL Group Capital must irrevocably deposit with the Indenture Trustee or any paying agent, in trust:

28


        Limitation on Liens.    So long as any Senior Debt Securities remain outstanding, FPL Group Capital will not secure any indebtedness with a lien on any shares of the capital stock of any of its majority-owned subsidiaries, which shares of capital stock FPL Group Capital now or hereafter directly owns, unless FPL Group Capital equally secures all Senior Debt Securities. However, this restriction does not apply to or prevent:

29


        Liens on any shares of the capital stock of any of FPL Group Capital's majority-owned subsidiaries, which shares of capital stock FPL Group Capital now or hereafter directly owns, other than liens described in (1) through (4) above, are referred to in this prospectus as "Restricted Liens." The foregoing limitation does not apply to the extent that FPL Group Capital creates any Restricted Liens to secure indebtedness that, together with all other indebtedness of FPL Group Capital secured by Restricted Liens, does not at the time exceed 5% of FPL Group Capital's Consolidated Capitalization. (Indenture, Section 608).

        For this purpose, "Consolidated Capitalization" means the sum of:

        The term "Consolidated Shareholders' Equity" as used above means the total assets of FPL Group Capital and its Consolidated Subsidiaries less all liabilities of FPL Group Capital and its Consolidated Subsidiaries. As used in this definition, the term "liabilities" means all obligations which would, in accordance with generally accepted accounting principles, be classified on a balance sheet as liabilities, including without limitation:

As used in this definition, "liabilities" includes preference or preferred stock of FPL Group Capital or any Consolidated Subsidiary only to the extent of any such preference or preferred stock that is subject to mandatory redemption or sinking fund provisions.

        The term "Consolidated Indebtedness" means total indebtedness as shown on the consolidated balance sheet of FPL Group Capital and its Consolidated Subsidiaries.

        The term "Consolidated Subsidiary," means at any date any direct or indirect majority-owned subsidiary whose financial statements would be consolidated with those of FPL Group Capital in FPL Group Capital's consolidated financial statements as of such date in accordance with generally accepted accounting principles. (Indenture, Section 608).

        The foregoing limitation does not limit in any manner the ability of:

30


        Consolidation, Merger, and Sale of Assets.    Under the Indenture, FPL Group Capital may not consolidate with or merge into any other entity or convey, transfer or lease its properties and assets substantially as an entirety to any entity, unless:

        The Indenture does not restrict FPL Group Capital in a merger in which FPL Group Capital is the surviving entity.

        Events of Default.    Each of the following is an event of default under the Indenture with respect to the Senior Debt Securities of any series:

        In the case of the third event of default listed above, the Indenture Trustee may extend the grace period. In addition, if registered owners of a particular series have given a notice of default, then registered owners of at least the same percentage of Senior Debt Securities of that series, together with the Indenture Trustee, may also extend the grace period. The grace period will be automatically extended if FPL Group Capital has initiated and is diligently pursuing corrective action. (Indenture, Section 801). An event of default with respect to the Senior Debt Securities of a particular series will not necessarily constitute an event of default with respect to Senior Debt Securities of any other series issued under the Indenture.

        Remedies.    If an event of default applicable to the Senior Debt Securities of one or more series, but not applicable to all outstanding Senior Debt Securities, exists, then either (i) the Indenture Trustee or (ii) the registered owners of at least 33% in aggregate principal amount of the Senior Debt Securities of each of the affected series may declare the principal of and accrued but unpaid interest on

31



all the Senior Debt Securities of that series to be due and payable immediately. However, under the Indenture, some Senior Debt Securities may provide for a specified amount less than their entire principal amount to be due and payable upon that declaration. These Senior Debt Securities are defined as "Discount Securities" in the Indenture.

        If the event of default is applicable to all outstanding Senior Debt Securities, then only the Indenture Trustee or the registered owners of at least 33% in aggregate principal amount of all outstanding Senior Debt Securities of all series, voting as one class, and not the registered owners of any one series, may make a declaration of acceleration. However, the event of default giving rise to the declaration relating to any series of Senior Debt Securities will be automatically waived, and that declaration and its consequences will be automatically rescinded and annulled, if, at any time after that declaration and before a judgment or decree for payment of the money due has been obtained:

        Other than its obligations and duties in case of an event of default under the Indenture, the Indenture Trustee is not obligated to exercise any of its rights or powers under the Indenture at the request or direction of any of the registered owners, unless those registered owners offer reasonable indemnity to the Indenture Trustee. (Indenture, Section 903). If they provide this reasonable indemnity, the registered owners of a majority in principal amount of any series of Senior Debt Securities will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Indenture Trustee, or exercising any trust or power conferred on the Indenture Trustee, with respect to the Senior Debt Securities of that series. However, if an event of default under the Indenture relates to more than one series of Senior Debt Securities, only the registered owners of a majority in aggregate principal amount of all affected series of Senior Debt Securities, considered as one class, will have the right to make that direction. Also, the direction must not violate any law or the Indenture, and may not expose the Indenture Trustee to personal liability in circumstances where its indemnity would not, in the Indenture Trustee's sole discretion, be adequate. (Indenture, Section 812).

        A registered owner of a Senior Debt Security has the right to institute a suit for the enforcement of payment of the principal of or premium, if any, or interest on that Senior Debt Security on or after the applicable due date specified in that Senior Debt Security. (Indenture, Section 808). No registered owner of Senior Debt Securities of any series will have any other right to institute any proceeding under the Indenture, or any other remedy under the Indenture, unless:

32


        FPL Group Capital is required to deliver to the Indenture Trustee an annual statement as to its compliance with all conditions and covenants under the Indenture. (Indenture, Section 606).

        Modification and Waiver.    Without the consent of any registered owner of Senior Debt Securities, FPL Group Capital and the Indenture Trustee may amend or supplement the Indenture for any of the following purposes:

33


        The registered owners of a majority in aggregate principal amount of the Senior Debt Securities of all series then outstanding may waive compliance by FPL Group Capital with certain restrictive provisions of the Indenture. (Indenture, Section 607). The registered owners of a majority in principal amount of the outstanding Senior Debt Securities of any series may waive any past default under the Indenture with respect to that series, except a default in the payment of principal, premium, if any, or interest and a default with respect to certain restrictive covenants or provisions of the Indenture that cannot be modified or amended without the consent of the registered owner of each outstanding Senior Debt Security of that series affected. (Indenture, Section 813).

        In addition to any amendments described above, if the Trust Indenture Act of 1939 is amended after the date of the Indenture in a way that requires changes to the Indenture or in a way that permits changes to, or the elimination of, provisions that were previously required by the Trust Indenture Act of 1939, the Indenture will be deemed to be amended to conform to that amendment of the Trust Indenture Act of 1939 or to make those changes, additions or eliminations. FPL Group Capital and the Indenture Trustee may, without the consent of any registered owners, enter into supplemental indentures to make that amendment. (Indenture, Section 1201).

        Except for any amendments described above, the consent of the registered owners of a majority in aggregate principal amount of the Senior Debt Securities of all series then outstanding, considered as one class, is required for all other modifications to the Indenture. However, if less than all of the series of Senior Debt Securities outstanding are directly affected by a proposed supplemental indenture, then the consent only of the registered owners of a majority in aggregate principal amount of outstanding Senior Debt Securities of all directly affected series, considered as one class, is required. But, if FPL Group Capital issues any series of Senior Debt Securities in more than one tranche and if the proposed supplemental indenture directly affects the rights of the registered owners of Senior Debt Securities of less than all of those tranches, then the consent only of the registered owners of a majority in aggregate principal amount of the outstanding Senior Debt Securities of all directly affected tranches, considered as one class, will be required. However, none of those amendments or modifications may:

34


        A supplemental indenture that changes or eliminates any provision of the Indenture that has expressly been included only for the benefit of one or more particular series or tranches of Senior Debt Securities, or that modifies the rights of the registered owners of Senior Debt Securities of that particular series or tranche with respect to that provision, will not affect the rights under the Indenture of the registered owners of the Senior Debt Securities of any other series or tranche. (Indenture, Section 1202).

        The Indenture provides that, in order to determine whether the registered owners of the required principal amount of the outstanding Senior Debt Securities have given any request, demand, authorization, direction, notice, consent or waiver under the Indenture, or whether a quorum is present at the meeting of the registered owners of Senior Debt Securities, Senior Debt Securities owned by FPL Group Capital or any other obligor upon the Senior Debt Securities or any affiliate of FPL Group Capital or of that other obligor (unless FPL Group Capital, that affiliate or that obligor owns all Senior Debt Securities outstanding under the Indenture, determined without regard to this provision) will be disregarded and deemed not to be outstanding. (Indenture, Section 101).

        If FPL Group Capital solicits any action under the Indenture from registered owners of Senior Debt Securities, FPL Group Capital may, at its option, by signing a written request to the Indenture Trustee, fix in advance a record date for determining the registered owners of Senior Debt Securities entitled to take that action. However, FPL Group Capital will not be obligated to do this. If FPL Group Capital fixes such a record date, that action may be taken before or after that record date, but only the registered owners of record at the close of business on that record date will be deemed to be registered owners of Senior Debt Securities for the purposes of determining whether registered owners of the required proportion of the outstanding Senior Debt Securities have authorized that action. For these purposes, the outstanding Senior Debt Securities will be computed as of the record date. Any action of a registered owner of any Senior Debt Security under the Indenture will bind every future registered owner of that Senior Debt Security, or any Senior Debt Security replacing that Senior Debt Security, with respect to anything that the Indenture Trustee or FPL Group Capital do, fail to do, or allow to be done in reliance on that action, whether or not that action is noted upon that Senior Debt Security. (Indenture, Section 104).

        Resignation and Removal of Indenture Trustee.    The Indenture Trustee may resign at any time with respect to any series of Senior Debt Securities by giving written notice of its resignation to FPL Group Capital. Also, the registered owners of a majority in principal amount of the outstanding Senior Debt Securities of one or more series of Senior Debt Securities may remove the Indenture Trustee at any time with respect to the Senior Debt Securities of that series, by delivering an instrument evidencing this action to the Indenture Trustee and FPL Group Capital. The resignation or removal of the Indenture Trustee and the appointment of a successor trustee will not become effective until a successor trustee accepts its appointment.

35


        Except with respect to an Indenture Trustee appointed by the registered owners of Senior Debt Securities, the Indenture Trustee will be deemed to have resigned and the successor will be deemed to have been appointed as trustee in accordance with the Indenture if:

        Notices.    Notices to registered owners of Senior Debt Securities will be sent by mail to the addresses of those registered owners as they appear in the security register for those Senior Debt Securities. (Indenture, Section 106).

        Title.    FPL Group Capital, the Indenture Trustee, and any agent of FPL Group Capital or the Indenture Trustee, may treat the person in whose name a Senior Debt Security is registered as the absolute owner of that Senior Debt Security, whether or not that Senior Debt Security is overdue, for the purpose of making payments and for all other purposes, regardless of any notice to the contrary. (Indenture, Section 308).

        Governing Law.    The Indenture and the Senior Debt Securities will be governed by, and construed in accordance with, the laws of the State of New York, without regard to conflict of laws principles thereunder, except to the extent that the law of any other jurisdiction is mandatorily applicable. (Indenture, Section 112).

DESCRIPTION OF FPL GROUP GUARANTEE OF
FPL GROUP CAPITAL SENIOR DEBT SECURITIES

        General.    This section briefly summarizes some of the provisions of the Guarantee Agreement, dated as of June 1, 1999, between FPL Group and The Bank of New York Mellon, as Guarantee Trustee. The Guarantee Agreement was executed for the benefit of the Indenture Trustee, which holds the Guarantee Agreement for the benefit of registered owners of the Senior Debt Securities covered by the Guarantee Agreement. This summary does not contain a complete description of the Guarantee Agreement. You should read this summary together with the Guarantee Agreement for a complete understanding of all the provisions. The Guarantee Agreement has previously been filed with the SEC and is an exhibit to the registration statement filed with the SEC of which this prospectus is a part. In addition, the Guarantee Agreement is qualified as an indenture under the Trust Indenture Act of 1939 and is therefore subject to the provisions of the Trust Indenture Act of 1939. You should read the Trust Indenture Act of 1939 for a complete understanding of its provisions.

        Under the Guarantee Agreement, FPL Group absolutely, irrevocably and unconditionally guarantees the prompt and full payment, when due and payable (including upon acceleration or redemption), of the principal, interest and premium, if any, on the Senior Debt Securities that are covered by the Guarantee Agreement to the registered owners of those Senior Debt Securities, according to the terms of those Senior Debt Securities and the Indenture. Pursuant to the Guarantee Agreement, all of the Senior Debt Securities are covered by the Guarantee Agreement except Senior Debt Securities that by their terms are expressly not entitled to the benefit of the Guarantee Agreement. All of the Offered Senior Debt Securities will be covered by the Guarantee Agreement. This guarantee is referred to in this prospectus as the "Guarantee." FPL Group is only required to make these payments if FPL Group Capital fails to pay or provide for punctual payment of any of those amounts on or before the expiration of any applicable grace periods. (Guarantee Agreement, Section 5.01). In the Guarantee Agreement, FPL Group has waived its right to require the Guarantee Trustee, the Indenture Trustee or the registered owners of Senior Debt Securities covered by the Guarantee Agreement to exhaust their remedies against FPL Group Capital prior to bringing suit against FPL Group. (Guarantee Agreement, Section 5.06).

        The Guarantee is a guarantee of payment when due (i.e., the guaranteed party may institute a legal proceeding directly against FPL Group to enforce its rights under the Guarantee Agreement without first instituting a legal proceeding against any other person or entity). The Guarantee is not a guarantee of collection. (Guarantee Agreement, Section 5.01).

        Except as otherwise stated in the related prospectus supplement, the covenants in the Guarantee Agreement would not give registered owners of the Senior Debt Securities covered by the Guarantee Agreement protection in the event of a highly-leveraged transaction involving FPL Group.

        Security and Ranking.    The Guarantee is an unsecured obligation of FPL Group and will rank equally and ratably with all other unsecured and unsubordinated indebtedness of FPL Group. The Guarantee will rank senior to the Preferred Trust Securities Guarantee, the Subordinated Guarantee and the FPL Group Junior Subordinated Debentures (each as defined below) and FPL Group's guarantee of FPL Group Capital's preferred stock. There is no limit on the amount of other indebtedness, including guarantees, that FPL Group may incur or issue.

        While FPL Group is a holding company that derives substantially all of its income from its operating subsidiaries, FPL Group's subsidiaries are separate and distinct legal entities and have no obligation to make any payments under the Guarantee Agreement or to make any funds available for such payment. Therefore, the Guarantee effectively is subordinated to all indebtedness and other liabilities, including trade payables, debt and preferred stock, incurred or issued by FPL Group's subsidiaries. In addition to trade liabilities, many of FPL Group's operating subsidiaries incur debt in order to finance their business activities. All of this indebtedness will effectively be senior to the

37



Guarantee. Neither the Indenture nor the Guarantee Agreement places any limit on the amount of liabilities, including debt or preferred stock, that FPL Group's subsidiaries may issue, guarantee or otherwise incur.

        Events of Default.    An event of default under the Guarantee Agreement will occur upon the failure of FPL Group to perform any of its payment obligations under the Guarantee Agreement. (Guarantee Agreement, Section 1.01). The registered owners of a majority of the aggregate principal amount of the outstanding Senior Debt Securities covered by the Guarantee Agreement have the right to:

        The Guarantee Trustee must give notice of any event of default under the Guarantee Agreement known to the Guarantee Trustee to the registered owners of Senior Debt Securities covered by the Guarantee Agreement within 90 days after the occurrence of that event of default, in the manner and to the extent provided in subsection (c) of Section 313 of the Trust Indenture Act of 1939, unless such event of default has been cured or waived prior to the giving of such notice. (Guarantee Agreement, Section 2.07). The registered owners of all outstanding Senior Debt Securities may waive any past event of default and its consequences. (Guarantee Agreement, Section 2.06).

        The Guarantee Trustee, the Indenture Trustee and the registered owners of Senior Debt Securities covered by the Guarantee Agreement have all of the rights and remedies available under applicable law and may sue to enforce the terms of the Guarantee Agreement and to recover damages for the breach of the Guarantee Agreement. The remedies of each of the Guarantee Trustee, the Indenture Trustee and the registered owners of Senior Debt Securities covered by the Guarantee Agreement, to the extent permitted by law, are cumulative and in addition to any other remedy now or hereafter existing at law or in equity. At the option of any of the Guarantee Trustee, the Indenture Trustee or the registered owners of Senior Debt Securities covered by the Guarantee Agreement, that person or entity may join FPL Group in any lawsuit commenced by that person or entity against FPL Group Capital with respect to any obligations under the Guarantee Agreement. Also, that person or entity may recover against FPL Group in that lawsuit, or in any independent lawsuit against FPL Group, without first asserting, prosecuting or exhausting any remedy or claim against FPL Group Capital. (Guarantee Agreement, Section 5.06).

        FPL Group is required to deliver to the Guarantee Trustee an annual statement as to its compliance with all conditions under the Guarantee Agreement. (Guarantee Agreement, Section 2.04).

        Modification.    FPL Group and the Guarantee Trustee may, without the consent of any registered owner of Senior Debt Securities covered by the Guarantee Agreement, agree to any changes to the Guarantee Agreement that do not materially adversely affect the rights of registered owners. The Guarantee Agreement also may be amended with the prior approval of the registered owners of a majority in aggregate principal amount of all outstanding Senior Debt Securities covered by the Guarantee Agreement. However, the right of any registered owner of Senior Debt Securities covered by the Guarantee Agreement to receive payment under the Guarantee Agreement on the due date of the Senior Debt Securities held by that registered owner, or to institute suit for the enforcement of that payment on or after that due date, may not be impaired or affected without the consent of that registered owner. (Guarantee Agreement, Section 6.01).

38


        Termination of the Guarantee Agreement.    The Guarantee Agreement will terminate and be of no further force and effect upon full payment of all Senior Debt Securities covered by the Guarantee Agreement. (Guarantee Agreement, Section 5.05).

        Governing Law.    The Guarantee Agreement will be governed by and construed in accordance with the laws of the State of New York, without regard to conflict of laws principles thereunder, except to the extent that the law of any other jurisdiction is mandatorily applicable. (Guarantee Agreement, Section 5.07).


DESCRIPTION OF FPL GROUP CAPITAL SUBORDINATED DEBT SECURITIES
AND FPL GROUP SUBORDINATED GUARANTEE

        FPL Group Capital may issue its subordinated debt securities (other than the FPL Group Capital Junior Subordinated Debentures (as defined below under "Description of FPL Group and FPL Group Capital Junior Subordinated Debentures and FPL Group Subordinated Guarantee")), in one or more series, under one or more Indentures, between FPL Group Capital and The Bank of New York Mellon, as trustee. The terms of any offered subordinated debt securities, including FPL Group's guarantee of FPL Group Capital's payment obligations under such subordinated debt securities, will be described in a supplement to this prospectus.

39



DESCRIPTION OF PREFERRED TRUST SECURITIES

        General.    The Trust may issue preferred trust securities and common trust securities under the Trust Agreement. The Trust Agreement pursuant to which the preferred trust securities of FPL Group Capital Trust will be issued is herein referred to as the "FPL Group Capital Trust Agreement," and the Trust Agreement pursuant to which preferred trust securities of FPL Group Trust will be issued is herein referred to as the "FPL Group Trust Agreement;" each of these agreements is referred to in this prospectus as the "Trust Agreement." The terms of the FPL Group Capital Trust Agreement and the FPL Group Trust Agreement are substantially the same. The preferred trust securities and common trust securities issued by the Trust are referred to in this prospectus as "Preferred Trust Securities" and "Common Trust Securities," respectively, and collectively as "Trust Securities." These Trust Securities will represent undivided beneficial interests in the assets of the Trust. Unless otherwise specified in a prospectus supplement in connection with the issuance of Trust Securities by FPL Group Capital Trust, the related FPL Group Capital Junior Subordinated Debentures (as defined below under "Description of FPL Group and FPL Group Capital Junior Subordinated Debentures and FPL Group Subordinated Guarantee") will be held by FPL Group Capital Trust, and in connection with the issuance of Trust Securities by FPL Group Trust, the related FPL Group Junior Subordinated Debentures (as defined below under "Description of FPL Group and FPL Group Capital Junior Subordinated Debentures and FPL Group Subordinated Guarantee") will be held by FPL Group Trust. This section briefly summarizes some of the provisions of the Trust Agreement. This summary does not contain a complete description of the Trust Agreement. You should read this summary together with the Trust Agreement for a complete understanding of all the provisions. The form of the Trust Agreement has previously been filed with the SEC and is an exhibit to the registration statement filed with the SEC of which this prospectus is a part. In addition, each Trust Agreement will be qualified as an indenture under the Trust Indenture Act of 1939 and is therefore subject to the provisions of the Trust Indenture Act of 1939. You should read the Trust Indenture Act of 1939 for a complete understanding of its provisions.

        In this section, any discussion of FPL Group Capital Trust, FPL Group Trust, Preferred Trust Securities and Common Trust Securities relate only to the applicable Trust. Holders of Preferred Trust Securities of FPL Group Capital Trust II, FPL Group Capital Trust III, FPL Group Trust I and FPL Group Trust II will be entitled to any of the benefits and protections contained in the Trust Agreement applicable to the particular Trust which issued the relevant Trust Securities and not with respect to any other Trust.

        The Preferred Trust Securities and Common Trust Securities issued by the Trust will be substantially the same except that, if there is an event of default under the Trust Agreement, as described below, that results from an event of default under the Subordinated Indenture (as such term is defined below under "Description of FPL Group and FPL Group Capital Junior Subordinated Debentures and FPL Group Subordinated Guarantee—General"), the right of FPL Group, as holder of the Common Trust Securities, to payment of distributions and upon liquidation or redemption will be subordinated to the rights of the holders of the Preferred Trust Securities. (Trust Agreement, Section 4.03). All of the Common Trust Securities will be owned by FPL Group. (Trust Agreement, Section 5.10).

        The following obligations and rights, in combination, have the effect of providing a full and unconditional guarantee of payments due on the Preferred Trust Securities issued by the Trust:

40


        No single one of the rights and obligations listed above standing alone or operating in conjunction with fewer than all of the other applicable rights and obligations constitutes a full and unconditional guarantee by FPL Group of the Preferred Trust Securities. It is only the combined operation of these rights and obligations that has the effect of providing a full and unconditional, but subordinated, guarantee as to payment by FPL Group of the Preferred Trust Securities.

        FPL Group Capital Trust will use the proceeds from its sale of the Trust Securities to purchase FPL Group Capital Junior Subordinated Debentures, and FPL Group Trust will use the proceeds from its sale of the Trust Securities to purchase FPL Group Junior Subordinated Debentures. (Trust Agreement, Section 2.05). The FPL Group Capital Junior Subordinated Debentures will be guaranteed by FPL Group pursuant to the Subordinated Guarantee described below and issued under an Indenture, dated as of March 1, 2004, among FPL Group Capital, FPL Group and The Bank of New York Mellon, as trustee, or another subordinated indenture among FPL Group Capital, FPL Group and The Bank of New York Mellon as specified in the related prospectus supplement. The FPL Group Junior Subordinated Debentures will be issued under a subordinated indenture between FPL Group and The Bank of New York Mellon, as trustee. In connection with the issuance of Trust Securities, the Junior Subordinated Debentures (as defined below under "Description of FPL Group and FPL Group Capital Junior Subordinated Debentures and FPL Group Subordinated Guarantee") will be held in trust for the benefit of holders of the applicable Preferred Trust Securities and Common Trust Securities. (Trust Agreement, Section 2.09).

        A prospectus supplement relating to the Preferred Trust Securities will include specific terms of those securities and of the Junior Subordinated Debentures issued in connection therewith. For a description of some specific terms that will affect both the Preferred Trust Securities and the Junior Subordinated Debentures, and holders' rights under each, see "Description of FPL Group and FPL Group Capital Junior Subordinated Debentures and FPL Group Subordinated Guarantee" below.

        Distributions.    The only income of the Trust available for distribution to the holders of Preferred Trust Securities will be payments on the applicable Junior Subordinated Debentures. (Trust Agreement, Section 8.01). If neither FPL Group Capital nor FPL Group makes interest payments on the FPL Group Capital Junior Subordinated Debentures, or if FPL Group does not make interest payments on the FPL Group Junior Subordinated Debentures, as the case may be, the Trust will not have funds available to pay distributions on Preferred Trust Securities. The payment of distributions, if and to the extent the Trust has sufficient funds available for the payment of such distributions, is guaranteed on a limited basis by FPL Group as described under "Description of Preferred Trust Securities Guarantee."

        If so specified in the related prospectus supplement, the issuer of the Junior Subordinated Debentures will have the option to defer the payment of interest from time to time on the Junior Subordinated Debentures for one or more periods, in which case, if the Junior Subordinated Debentures were issued in connection with Preferred Trust Securities, distributions on the Preferred Trust Securities would be deferred during any such period. Unless otherwise provided in the related prospectus supplement, distributions would, however, continue to accumulate. (Trust Agreement, Section 4.01). Unless otherwise provided in the related prospectus supplement, during any optional deferral period, or for so long as an "Event of Default" under the Subordinated Indenture resulting from a payment default or a payment default under the Preferred Trust Securities Guarantee has occurred and is continuing, neither FPL Group nor FPL Group Capital, with respect to deferral of the

41



payment of interest on the FPL Group Capital Junior Subordinated Debentures, nor FPL Group, with respect to the deferral of the payment of interest on the FPL Group Junior Subordinated Debentures, may:

42


        The exceptions in clauses (h) and (i) above are not applicable to an optional deferral period on the FPL Group Junior Subordinated Debentures.

        Unless otherwise provided in the related prospectus supplement, (i) before an optional deferral period ends, FPL Group Capital or FPL Group, as the case may be, may further defer the payment of interest and (ii) after any optional deferral period and the payment of all amounts then due, FPL Group Capital or FPL Group, as the case may be, may select a new optional deferral period. No interest period may be deferred beyond the maturity of the Junior Subordinated Debentures.

        Redemption.    Whenever Junior Subordinated Debentures are repaid, whether at maturity or earlier redemption, the Property Trustee will apply the proceeds to redeem a like amount of Preferred Trust Securities and Common Trust Securities. (Trust Agreement, Section 4.02(a)).

        Preferred Trust Securities will be redeemed at the redemption price plus accrued and unpaid distributions with the proceeds from the contemporaneous redemption or repayment of Junior Subordinated Debentures. Redemptions of the Preferred Trust Securities will be made on a redemption date only if the Trust has funds available for the payment of the redemption price plus accrued and unpaid distributions. (Trust Agreement, Section 4.02(c)).

        Holders of Preferred Trust Securities will be given not less than 30 nor more than 60 days' notice of any redemption. (Trust Agreement, Section 4.02(b)). On or before the redemption date, the Trust will irrevocably deposit with the paying agent for Preferred Trust Securities sufficient funds and will give the paying agent irrevocable instructions and authority to pay the redemption price plus accrued and unpaid distributions to the holders upon surrender of their Preferred Trust Securities. Distributions payable on or before a redemption date will be payable to the holders on the record date for the distribution payment. If notice is given and funds are deposited as required, then on the redemption date all rights of holders of the Preferred Trust Securities called for redemption will cease, except the right of the holders to receive the redemption price plus accrued and unpaid distributions, and the Preferred Trust Securities will cease to be outstanding. No interest will accrue on amounts payable on the redemption date. In the event that any date fixed for redemption of Preferred Trust Securities is not a business day, then payment will be made on the next business day, except that, if such business day falls in the next calendar year, then payment will be made on the immediately preceding business day. No interest will be payable because of any such delay. If payment of Preferred Trust Securities called for redemption is improperly withheld or refused and not paid either by the Trust or by FPL Group pursuant to the Preferred Trust Securities Guarantee, distributions on such Preferred Trust Securities will continue to accrue to the date of payment. In that event, the actual payment date will be considered the date fixed for redemption for purposes of calculating the redemption price plus accrued and unpaid distributions. (Trust Agreement, Section 4.02(d)).

        Subject to applicable law, including United States federal securities laws, FPL Group or its affiliates may at any time and from time to time purchase outstanding Preferred Trust Securities by tender, in the open market or by private agreement.

        If Preferred Trust Securities are partially redeemed on a redemption date, a corresponding percentage of the Common Trust Securities will be redeemed. The particular Preferred Trust Securities

43



to be redeemed will be selected not more than 60 days prior to the redemption date by the Property Trustee by such method as the Property Trustee shall deem fair, taking into account the denominations in which they were issued. The Property Trustee will promptly notify the Preferred Trust Security registrar in writing of the Preferred Trust Securities selected for redemption and, where applicable, the partial amount to be redeemed. (Trust Agreement, Section 4.02(f)).

        Subordination of Common Trust Securities.    Payment of distributions on, and the redemption price, plus accrued and unpaid distributions, of, the Preferred Trust Securities and Common Trust Securities shall be made pro rata based on the liquidation preference amount of such securities. However, if on any distribution payment date or redemption date an event of default under the Trust Agreement resulting from an event of default under the related Subordinated Indenture has occurred and is continuing, no payment on any Common Trust Security shall be made until all payments due on the Preferred Trust Securities have been made. In that case, funds available to the Property Trustee shall first be applied to the payment in full of all distributions on, or the redemption price plus accrued and unpaid distributions of, Preferred Trust Securities then due and payable. (Trust Agreement, Section 4.03(a)).

        If an event of default under the Trust Agreement results from an event of default under the related Subordinated Indenture, the holder of Common Trust Securities cannot take action with respect to the Trust Agreement default until the effect of all defaults with respect to the Preferred Trust Securities has been cured, waived or otherwise eliminated. Until the event of default under the Trust Agreement with respect to Preferred Trust Securities has been cured, waived or otherwise eliminated, the Property Trustee shall, to the fullest extent permitted by law, act solely on behalf of the holders of Preferred Trust Securities and not the holder of the Common Trust Securities, and only the holders of Preferred Trust Securities will have the right to direct the Property Trustee to act on their behalf. (Trust Agreement, Section 4.03(b)).

        Liquidation Distribution upon Dissolution.    The Trust will be dissolved and liquidated by the Property Trustee on the first to occur of:

        If a dissolution of the Trust occurs, the Trust will be liquidated by the Property Trustee as expeditiously as the Property Trustee determines to be appropriate. If a dissolution of the Trust occurs other than by redemption of all the Preferred Trust Securities, the Property Trustee will provide for the satisfaction of liabilities of creditors, if any, and distribute to each holder of the Preferred Trust Securities and Common Trust Securities a proportionate amount of Junior Subordinated Debentures. If a distribution of Junior Subordinated Debentures is determined by the Property Trustee not to be practical, holders of Preferred Trust Securities will be entitled to receive, out of the assets of the Trust after adequate provision for the satisfaction of liabilities of creditors, if any, an amount equal to the aggregate liquidation preference of the Preferred Trust Securities plus accrued and unpaid distributions thereon to the date of payment. If this liquidation distribution can be paid only in part because the Trust has insufficient assets available to pay in full the aggregate liquidation distribution, then the amounts payable by the Trust on the Preferred Trust Securities shall be paid on a pro rata basis. FPL Group, as holder of the Common Trust Securities, will be entitled to receive distributions upon any dissolution pro rata with the holders of the Preferred Trust Securities, except that if an event of default (or event that, with the lapse of time or giving of notice, would become such an event of default) has occurred and is continuing under the related Subordinated Indenture, the Preferred Trust Securities will have a preference over the Common Trust Securities. (Trust Agreement, Section 9.04).

44


        Events of Default; Notice.    Any one of the following events will be an event of default under the Trust Agreement whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body:

        Within 90 days after the occurrence of any default known to the Property Trustee, the Property Trustee shall transmit to the holders of Preferred Trust Securities, FPL Group and the Administrative Trustees notice of any such default, unless that default shall have been cured or waived. (Trust Agreement, Section 8.02).

        A holder of Preferred Trust Securities may directly institute a proceeding to enforce payment when due to the holder of the Preferred Trust Securities of the principal of or interest on Junior Subordinated Debentures having a principal amount equal to the aggregate liquidation preference amount of the holder's Preferred Trust Securities. The holders of Preferred Trust Securities have no other rights to exercise directly any other remedies available to the holder of the Junior Subordinated Debentures unless the trustees under the Trust Agreement fail to do so. (Trust Agreement, Section 6.01(a)).

        Removal of Trustees.    Unless an event of default under the related Subordinated Indenture has occurred and is continuing, the holder of the Common Trust Securities may remove any trustee under the Trust Agreement at any time. If an event of default under the Subordinated Indenture has occurred and is continuing, the holders of a majority of the total liquidation preference amount of the outstanding Preferred Trust Securities may remove the Property Trustee or the Delaware Trustee, or both of them. The holder of the Common Trust Securities may remove any Administrative Trustee at any time. Any resignation or removal of a trustee under the Trust Agreement will take effect only on the acceptance of appointment by the successor trustee. (Trust Agreement, Section 8.10).

        Holders of Preferred Trust Securities will have no right to appoint or remove the Administrative Trustees of the Trust, who may be appointed, removed or replaced solely by FPL Group as the holder of the Common Trust Securities. (Trust Agreement, Section 8.10).

        Voting Rights.    Except as provided below and under "Description of Preferred Trust Securities Guarantee—Modification and Assignment, " and as otherwise required by law or the Trust Agreement, the holders of Preferred Trust Securities will have no voting rights.

45


        While Junior Subordinated Debentures are held by the Property Trustee, the Property Trustee shall not:

without, in each case, obtaining the prior approval of the holders of Preferred Trust Securities having at least a majority of the aggregate liquidation preference amount of all outstanding Preferred Trust Securities of the Trust. Where a consent of each holder of Junior Subordinated Debentures affected is required, no consent shall be given by the Property Trustee without the prior consent of each holder of the Preferred Trust Securities affected. The Property Trustee shall not revoke any action previously authorized or approved by a vote of the holders of Preferred Trust Securities, except pursuant to the subsequent vote of the holders of Preferred Trust Securities. (Trust Agreement, Section 6.01(b)). If the Property Trustee fails to enforce its rights, as holder, under the Junior Subordinated Debentures or the Trust Agreement, a holder of the Preferred Trust Securities may institute a legal proceeding directly against FPL Group or FPL Group Capital, as the case may be, to enforce the Property Trustee's rights under the Junior Subordinated Debentures or the Trust Agreement without first instituting any legal proceeding against the Property Trustee or anyone else. (Trust Agreement, Section 6.01(a)). The Property Trustee shall notify all holders of Preferred Trust Securities of any notice of default received from the Subordinated Indenture Trustee. The Property Trustee shall not take any action approved by the consent of the holders of Preferred Trust Securities without an opinion of counsel experienced in those matters to the effect that the Trust will be classified as a grantor trust and not as an association taxable as a corporation for United States federal income tax purposes on account of that action. (Trust Agreement, Section 6.01(b)).

        Holders of Preferred Trust Securities may give any required approval at a meeting convened for such purpose or by written consent without prior notice. (Trust Agreement, Section 6.06). The Administrative Trustees will give notice of any meeting at which holders of Preferred Trust Securities are entitled to vote. (Trust Agreement, Section 6.02).

        No vote or consent of the holders of Preferred Trust Securities will be required for the Trust to redeem and cancel Preferred Trust Securities in accordance with the Trust Agreement.

        Notwithstanding that holders of Preferred Trust Securities are entitled to vote or consent under any of the circumstances described above, any Preferred Trust Securities that are owned by FPL Group Capital, FPL Group, any Administrative Trustee or any affiliate of any of them, shall be treated as if they were not outstanding for purposes of such vote or consent. (Trust Agreement, Section 1.01).

        Amendments.    The Trust Agreement may be amended from time to time by a majority of its Administrative Trustees and FPL Group, without the consent of any holders of Preferred Trust Securities or the other trustees under the Trust Agreement in order to:

46


        No amendment described above may materially adversely affect the interests of any holder of Preferred Trust Securities or Common Trust Securities without the applicable consents required pursuant to the following two paragraphs. Any of the amendments of the Trust Agreement described in paragraph (1) above shall become effective when notice of the amendment is given to the holders of Preferred Trust Securities and Common Trust Securities in accordance with the provisions of the Trust Agreement. (Trust Agreement, Section 10.03(a)).

        Except as provided below, any provision of the Trust Agreement may be amended by the Administrative Trustees and FPL Group with:

        Each affected holder of Preferred Trust Securities must consent to any amendment to the Trust Agreement that:

        Form, Exchange and Transfer.    Preferred Trust Securities may be exchanged for other Preferred Trust Securities in any authorized denomination and of like tenor and aggregate liquidation preference. (Trust Agreement, Section 5.04).

        Subject to the terms of the Trust Agreement, Preferred Trust Securities may be presented for exchange as provided above or for registration of transfer, duly endorsed or accompanied by a duly executed instrument of transfer, at the office of the Preferred Trust Security registrar. The Administrative Trustees may designate FPL Group or FPL Group Capital or any affiliate of either of them, as the Preferred Trust Security registrar. The Property Trustee will initially act as the Preferred Trust Security registrar and transfer agent. (Trust Agreement, Section 5.08). No service charge will be made for any registration of transfer or exchange of Preferred Trust Securities, but the Preferred Trust Security registrar may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with the transfer or exchange. A transfer or exchange will be made when

47



the Preferred Trust Security registrar and Administrative Trustees are satisfied with the documents of title and identity of the person making the request. (Trust Agreement, Section 5.04). The Administrative Trustees may at any time designate another transfer agent and registrar or rescind the designation of any transfer agent and registrar or approve a change in the office through which any transfer agent and registrar acts, except that FPL Group will, or will cause the Preferred Trust Security registrar to, maintain an office or agency in The City of New York where Preferred Trust Securities may be transferred or exchanged. (Trust Agreement, Sections 2.07(a) and 5.08).

        The Trust will not be required to:

        Payment on Preferred Trust Securities and Paying Agent.    Unless otherwise stated in a prospectus supplement, payments in respect of the Preferred Trust Securities will be made on the applicable distribution dates by check mailed to the address of the holder entitled thereto as such address appears on the Preferred Trust Security register. (Trust Agreement, Section 4.04). The paying agent shall initially be the Property Trustee and any co-paying agent chosen by the Property Trustee that is acceptable to the Administrative Trustees, FPL Group and, in the case of Preferred Trust Securities issued by FPL Group Capital Trust, FPL Group Capital. The paying agent may resign upon 30 days' written notice to the Administrative Trustees, the Property Trustee, FPL Group and, in the case of Preferred Trust Securities issued by FPL Group Capital Trust, FPL Group Capital. In the event that the Property Trustee shall no longer be the paying agent, the Administrative Trustees shall appoint a successor, which shall be a bank, trust company or affiliate of FPL Group reasonably acceptable to the Property Trustee, FPL Group, and, in the case of Preferred Trust Securities issued by FPL Group Capital Trust, FPL Group Capital, to act as paying agent. (Trust Agreement, Section 5.09).

        Duties of the Trustees.    The Delaware Trustee will act as the resident trustee in the State of Delaware and will have no other significant duties. The Property Trustee will hold the Junior Subordinated Debentures on behalf of the Trust and will maintain a payment account with respect to the Preferred Trust Securities and Common Trust Securities, and will also act as trustee under the Trust Agreement for the purposes of the Trust Indenture Act of 1939. (Trust Agreement, Sections 2.06 and 2.07(b)).

        The Administrative Trustees of the Trust are authorized and directed to conduct the affairs of the Trust and to operate the Trust so that

        In this regard, FPL Group and the Administrative Trustees are authorized to take any action, not inconsistent with applicable law, the certificate of trust or the Trust Agreement, that FPL Group and

48



the Administrative Trustees determine in their discretion to be necessary or desirable for those purposes, as long as the action does not materially adversely affect the interests of the holders of the Preferred Trust Securities. (Trust Agreement, Section 2.07(d)).

        Miscellaneous.    Holders of the Preferred Trust Securities have no preemptive or similar rights. (Trust Agreement, Section 5.13).

        Notices.    Notices to holders of Preferred Trust Securities will be sent by mail to the addresses of those holders as they appear in the security register for those Preferred Trust Securities. (Trust Agreement, Section 6.02).

        Title.    The Property Trustee, the Delaware Trustee, the Administrative Trustees, and the Preferred Trust Security registrar and transfer agent, and any agent of the Property Trustee, the Delaware Trustee, the Administrative Trustees, or the Preferred Trust Security registrar and transfer agent, may treat the person in whose name a Preferred Trust Security is registered as the absolute owner of that Preferred Trust Security for the purpose of receiving distributions and all other purposes, regardless of any notice to the contrary. (Trust Agreement, Section 5.06).

        Governing Law.    The Trust Agreement, the Preferred Trust Securities and the Common Trust Securities will be governed by and construed in accordance with the laws of the State of Delaware, without regard to conflict of laws principles thereunder, except to the extent that the law of any other jurisdiction is mandatorily applicable. (Trust Agreement, Section 10.05).

DESCRIPTION OF PREFERRED TRUST SECURITIES GUARANTEE

        General.    This section briefly summarizes some of the provisions of the Preferred Trust Securities Guarantee Agreement that FPL Group will execute and deliver for the benefit of the holders of the Preferred Trust Securities issued by FPL Group Capital Trust and FPL Group Trust. The terms of these agreements are substantially the same, and they are referred to in this prospectus as the "Preferred Trust Securities Guarantee Agreement." This summary does not contain a complete description of the Preferred Trust Securities Guarantee Agreement. You should read this summary together with the Preferred Trust Securities Guarantee Agreement for a complete understanding of all the provisions. The form of the Preferred Trust Securities Guarantee Agreement has previously been filed with the SEC and is an exhibit to the registration statement filed with the SEC of which this prospectus is a part. In addition, the Preferred Trust Securities Guarantee Agreement will be qualified as an indenture under the Trust Indenture Act of 1939 and is therefore subject to the provisions of the Trust Indenture Act of 1939. You should read the Trust Indenture Act of 1939 for a complete understanding of its provisions.

        The Bank of New York Mellon will act as Preferred Trust Securities Guarantee Trustee under the Preferred Trust Securities Guarantee Agreement and will hold the Preferred Trust Securities Guarantee for the benefit of the holders of the Preferred Trust Securities.

        General Terms of the Preferred Trust Securities Guarantee.    FPL Group will absolutely, irrevocably and unconditionally agree to make the guarantee payments listed below in full to the holders of the Preferred Trust Securities if they are not made by the Trust, as and when due, regardless of any defense, right of set-off or counterclaim that the Trust may have or assert. (Preferred Trust Securities Guarantee Agreement, Section 5.01). The following payments will be subject to the Preferred Trust Securities Guarantee (without duplication):

(Preferred Trust Securities Guarantee Agreement, Section 1.01). FPL Group's obligation to make a guarantee payment may be satisfied by either making a direct payment of the required amounts by FPL Group to the holders of Preferred Trust Securities or causing the Trust to pay such amounts to those holders. (Preferred Trust Securities Guarantee Agreement, Section 5.01).

50


        The Preferred Trust Securities Guarantee will be a guarantee, subject to certain subordination provisions, as to payment with respect to the Preferred Trust Securities, but will not apply to any payment of distributions if and to the extent that the Trust does not have funds legally available to make those payments. (Preferred Trust Securities Guarantee Agreement, Sections 1.01 and 5.05). If neither FPL Group Capital nor FPL Group makes interest payments on the FPL Group Capital Junior Subordinated Debentures held by a Trust and if FPL Group does not make interest payments on the FPL Group Junior Subordinated Debentures held by a Trust, in each case the applicable Trust will not have funds available to pay distributions on the Preferred Trust Securities.

        The following obligations and rights, in combination, have the effect of providing a full and unconditional guarantee of payments due on the Preferred Trust Securities issued by the Trust:

        No single one of the rights and obligations listed above standing alone or operating in conjunction with fewer than all of the other applicable rights and obligations constitutes a full and unconditional guarantee by FPL Group of the Preferred Trust Securities. It is only the combined operation of these rights and obligations that has the effect of providing a full and unconditional, but subordinated, guarantee as to payment by FPL Group of the Preferred Trust Securities.

        Except as otherwise stated in the related prospectus supplement, the covenants in the Preferred Trust Securities Guarantee Agreement would not give holders of the Preferred Trust Securities protection in the event of a highly-leveraged transaction involving FPL Group.

        Security and Ranking.    The Preferred Trust Securities Guarantee will be an unsecured obligation of FPL Group and will rank:

        The Preferred Trust Securities Guarantee Agreement does not limit the amount of other indebtedness, including guarantees, that FPL Group may issue or incur or the amount of preferred or preference stock it may issue.

        The Trust Agreement provides that by accepting Preferred Trust Securities, a holder agrees to the subordination provisions and other terms of the Preferred Trust Securities Guarantee. (Trust Agreement, Section 5.02).

51


        The Preferred Trust Securities Guarantee will be a guarantee of payment and not of collection, that is, the guaranteed party may institute a legal proceeding directly against FPL Group to enforce its rights under the Preferred Trust Securities Guarantee without first instituting a legal proceeding against anyone else. (Preferred Trust Securities Guarantee Agreement, Sections 5.04 and 5.05).

        While FPL Group is a holding company that derives substantially all of its income from its operating subsidiaries, FPL Group's subsidiaries are separate and distinct legal entities and have no obligation to make any payments under the Preferred Trust Securities Guarantee or to make any funds available for such payment. Therefore, the Preferred Trust Securities Guarantee will effectively be subordinated to all indebtedness and other liabilities, including trade payables, debt and preferred stock, incurred or issued by FPL Group's subsidiaries. In addition to trade liabilities, many of FPL Group's operating subsidiaries incur debt in order to finance their business activities. All of this indebtedness will effectively be senior to the Preferred Trust Securities Guarantee. Neither the Subordinated Indenture nor the Preferred Trust Securities Guarantee Agreement places any limit on the amount of liabilities, including debt or preferred stock, that FPL Group's subsidiaries may issue, guarantee or otherwise incur. See "Description of FPL Group Common Stock—Common Stock Terms—Dividend Rights" for a description of contractual restrictions on the dividend-paying ability of some of FPL Group's subsidiaries.

        Events of Default.    An event of default under the Preferred Trust Securities Guarantee Agreement will occur upon failure of FPL Group to perform any of its payment obligations under the Preferred Trust Securities Guarantee Agreement, which failure has not been cured within 90 days of receipt of notice thereof. (Preferred Trust Securities Guarantee Agreement, Section 1.01). Upon an event of default, the holders of the Preferred Trust Securities having a majority of the aggregate liquidation preference of the Preferred Trust Securities have the right to:

        Any holder of the Preferred Trust Securities may enforce the Preferred Trust Securities Guarantee, or institute a legal proceeding directly against FPL Group to enforce the Preferred Trust Securities Guarantee Trustee's rights under the Preferred Trust Securities Guarantee Agreement without first instituting a legal proceeding against the Trust, the Preferred Trust Securities Guarantee Trustee or anyone else. (Preferred Trust Securities Guarantee Agreement, Section 5.04). The holders of the Preferred Trust Securities having a majority of the aggregate liquidation preference of the Preferred Trust Securities may waive any past event of default and its consequences. (Preferred Trust Securities Guarantee Agreement, Section 2.06).

        FPL Group will be required to deliver to the Preferred Trust Securities Guarantee Trustee an annual statement as to its compliance with all conditions under the Preferred Trust Securities Guarantee Agreement. (Preferred Trust Securities Guarantee Agreement, Section 2.04).

        Modification and Assignment.    No consent of holders of Preferred Trust Securities is required for changes to the Preferred Trust Securities Guarantee Agreement that do not materially adversely affect their rights. Except as provided below, changes to the Preferred Trust Securities Guarantee Agreement that materially adversely affect the rights of Preferred Trust Securities require the prior approval of the holders of Preferred Trust Securities having at least a majority of the aggregate liquidation preference amount of the outstanding Preferred Trust Securities. Each affected holder of Preferred Trust Securities must consent to any amendment to the Preferred Trust Securities Guarantee Agreement that impairs

52



the right of such holder to receive guarantee payments under the Preferred Trust Securities Guarantee Agreement or to institute suit for enforcement of any such payment. (Preferred Trust Securities Guarantee Agreement, Section 8.01).

        All guarantees and agreements contained in the Preferred Trust Securities Guarantee Agreement will bind the successors, assigns, receivers, trustees and representatives of FPL Group and will inure to the benefit of the holders of the Preferred Trust Securities then outstanding. (Preferred Trust Securities Guarantee Agreement, Section 8.02).

        Termination of the Preferred Trust Securities Guarantee.    The Preferred Trust Securities Guarantee Agreement will terminate and be of no further force and effect upon:

        However, the Preferred Trust Securities Guarantee will continue to be effective or will be reinstated, as the case may be, if at any time, as result of the subordination provisions or any mistake or any judicial proceeding or otherwise, any holder of Preferred Trust Securities must return any sums paid under the Preferred Trust Securities or the Preferred Trust Securities Guarantee. (Preferred Trust Securities Guarantee Agreement, Section 7.01).

        Governing Law.    The Preferred Trust Securities Guarantee Agreement provides that it is to be governed by and construed in accordance with the laws of the State of New York, without regard to conflict of laws principles thereunder, except to the extent that the law of any other jurisdiction is mandatorily applicable. (Preferred Trust Securities Guarantee Agreement, Section 8.06).

DESCRIPTION OF FPL GROUP AND FPL GROUP CAPITAL
JUNIOR SUBORDINATED DEBENTURES AND
FPL GROUP SUBORDINATED GUARANTEE

        General.    The junior subordinated debentures issued by FPL Group Capital are referred to in this prospectus as the "FPL Group Capital Junior Subordinated Debentures." The junior subordinated debentures issued by FPL Group are referred to in this prospectus as the "FPL Group Junior Subordinated Debentures," and, together with the FPL Group Capital Junior Subordinated Debentures, are referred to as the "Junior Subordinated Debentures." The FPL Group Capital Junior Subordinated Debentures will be issued by FPL Group Capital in one or more series under an Indenture, dated as of March 1, 2004, among FPL Group Capital, FPL Group and The Bank of New York Mellon, as trustee, an Indenture, dated as of September 1, 2006, among FPL Group Capital, FPL Group and The Bank of New York Mellon, as trustee, or another subordinated indenture among FPL Group Capital, FPL Group and The Bank of New York Mellon as specified in the related prospectus supplement. The indenture or indentures pursuant to which FPL Group Capital Junior Subordinated Debentures may be issued, as they may be amended from time to time, are referred to in this prospectus as the "FPL Group Capital Subordinated Indenture." The indenture or indentures pursuant to which FPL Group Junior Subordinated Debentures may be issued, as they may be amended from time to time, are referred to in this prospectus as the "FPL Group Subordinated Indenture." The FPL Group Junior Subordinated Debentures will be issued by FPL Group in one or more series under an indenture or indentures between FPL Group and The Bank of New York Mellon, as trustee. Each of the FPL Group Capital Subordinated Indenture and the FPL Group Subordinated Indenture, as each may be amended and supplemented from time to time, is referred to in this prospectus as the "Subordinated Indenture." The Bank of New York Mellon, as trustee under each Subordinated Indenture, is referred to in this prospectus as the "Subordinated Indenture Trustee." The Subordinated Indenture provides for the issuance from time to time of subordinated debt in an unlimited amount. The Junior Subordinated Debentures and all other subordinated debt issued previously or hereafter under the Subordinated Indenture are collectively referred to in this prospectus as the "Subordinated Indenture Securities."

        This section briefly summarizes some of the terms of the Junior Subordinated Debentures, the Subordinated Guarantee applicable to the FPL Group Capital Junior Subordinated Debentures, and some of the provisions of the Subordinated Indenture. This summary does not contain a complete description of the Junior Subordinated Debentures, the Subordinated Guarantee or the Subordinated Indenture. You should read this summary together with the Subordinated Indenture and the officer's certificates or other documents creating the Junior Subordinated Debentures and the Subordinated Guarantee for a complete understanding of all the provisions and for the definitions of some terms used in this summary. The Subordinated Indenture (which, in the case of the FPL Group Capital Subordinated Indenture, contains the Subordinated Guarantee), the forms of officer's certificate that may be used to create a series of Junior Subordinated Debentures and the forms of the Junior Subordinated Debentures have previously been filed with the SEC, and are exhibits to the registration statement. In addition, each Subordinated Indenture will be qualified under the Trust Indenture Act of 1939 and is therefore subject to the provisions of the Trust Indenture Act of 1939. You should read the Trust Indenture Act of 1939 for a complete understanding of its provisions.

        Each issue of the FPL Group Capital Junior Subordinated Debentures and the FPL Group Junior Subordinated Debentures will constitute a separate series under the respective Subordinated Indenture.

        In connection with the issuance of Trust Securities, the aggregate principal amount of each series will be limited to the sum of the aggregate liquidation preference amount of the related Preferred Trust Securities and the consideration paid by FPL Group for the related Common Trust Securities. The Property Trustee will hold the FPL Group Capital Junior Subordinated Debentures on behalf of FPL

54



Group Capital Trust, or will hold the FPL Group Junior Subordinated Debentures on behalf of FPL Group Trust, as the case may be, as trust assets.

        All FPL Group Capital Junior Subordinated Debentures of one series need not be issued at the same time, and a series may be re-opened for issuances of additional FPL Group Capital Junior Subordinated Debentures of such series. This means that FPL Group Capital may from time to time, without notice to, or the consent of the existing holders of the FPL Group Capital Junior Subordinated Debentures of a particular series, create and issue additional FPL Group Capital Junior Subordinated Debentures of such series. Such additional FPL Group Capital Junior Subordinated Debentures will have the same terms as the previously-issued FPL Group Capital Junior Subordinated Debentures of such series in all respects (except for the payment of interest accruing prior to the issue date of the additional FPL Group Capital Junior Subordinated Debentures or except for the first payments of interest following the issue date of the additional FPL Group Capital Junior Subordinated Debentures) so that the additional FPL Group Capital Junior Subordinated Debentures may be consolidated and form a single series with the previously-issued FPL Group Capital Junior Subordinated Debentures of such series.

        Similarly, all FPL Group Junior Subordinated Debentures of one series need not be issued at the same time, and a series may be re-opened for issuances of additional FPL Group Junior Subordinated Debentures of such series, in the manner described in the paragraph above with respect to FPL Group Capital Junior Subordinated Debentures.

        The FPL Group Capital Junior Subordinated Debentures will be unsecured, subordinated obligations of FPL Group Capital which rank junior to all of FPL Group Capital's Senior Indebtedness. The FPL Group Junior Subordinated Debentures will be unsecured, subordinated obligations of FPL Group which rank junior to all of FPL Group's Senior Indebtedness. The term "Senior Indebtedness" with respect to FPL Group Capital or FPL Group, as the case may be, will be defined in the related prospectus supplement. All Junior Subordinated Debentures issued under a particular Subordinated Indenture will rank equally and ratably with all other Junior Subordinated Debentures issued under that Subordinated Indenture, except to the extent that FPL Group Capital or FPL Group, as the case may be, elects to provide security with respect to any series of Junior Subordinated Debentures without providing that security to all outstanding Junior Subordinated Debentures in accordance with the respective Subordinated Indenture. Junior Subordinated Debentures issued under a particular Subordinated Indenture may rank senior to, pari passu with, or junior to, Junior Subordinated Debentures issued by the same issuer under another Subordinated Indenture. The FPL Group Capital Junior Subordinated Debentures will be unconditionally guaranteed by FPL Group as to payment of principal, and any interest and premium, pursuant to a Subordinated Guarantee of FPL Group, included in the Subordinated Indenture for such FPL Group Capital Junior Subordinated Debentures, which Subordinated Guarantee ranks junior to all of FPL Group's Senior Indebtedness, and may rank senior to, pari passu with, or junior to, FPL Group's obligations under a separate Subordinated Guarantee. See "—Subordinated Guarantee of FPL Group Capital Junior Subordinated Debentures" below.

        Although the FPL Group Capital Junior Subordinated Debentures and the FPL Group Junior Subordinated Debentures are discussed together in this section of the prospectus, FPL Group will have no obligation with respect to the FPL Group Capital Junior Subordinated Debentures except in connection with the Subordinated Guarantee, and FPL Group Capital will have no obligation with respect to the FPL Group Junior Subordinated Debentures.

        Each series of Junior Subordinated Debentures that may be issued under each Subordinated Indenture may have different terms. FPL Group Capital or FPL Group, as the case may be, will include some or all of the following information about a specific series of Junior Subordinated

55



Debentures in the particular prospectus supplement relating to that specific series of Junior Subordinated Debentures:

56


        Except as otherwise stated in the related prospectus supplement, the covenants in the Subordinated Indenture would not give registered owners of Junior Subordinated Debentures protection in the event of a highly-leveraged transaction involving FPL Group Capital, in the case of the FPL Group Capital Junior Subordinated Debentures, or FPL Group.

Subordination.

57


if, in either case, any of the following occurs:

        Upon any distribution of assets of FPL Group Capital, or of FPL Group, as the case may be, to creditors in connection with any insolvency, bankruptcy or similar proceeding, all principal of, and premium, if any, and interest due or to become due on all Senior Indebtedness of FPL Group Capital, or of FPL Group, as the case may be, must be paid in full before the holders of the Junior Subordinated Debentures are entitled to receive or retain any payment from such distribution. (FPL Group Capital Subordinated Indenture, Section 1502; FPL Group Subordinated Indenture, Section 1402).

        While FPL Group Capital is a holding company that derives substantially all of its income from its operating subsidiaries, FPL Group Capital's subsidiaries are separate and distinct legal entities and have no obligation to make any payments on the FPL Group Capital Subordinated Indenture Securities or to make any funds available for such payment. Therefore, FPL Group Capital Subordinated Indenture Securities will effectively be subordinated to all indebtedness and other liabilities, including trade payables, debt and preferred stock, incurred or issued by FPL Group Capital's subsidiaries. In addition to trade liabilities, many of FPL Group Capital's operating subsidiaries incur debt in order to finance their business activities. All of this indebtedness will effectively be senior to the FPL Group Capital Subordinated Indenture Securities. The FPL Group Capital Subordinated Indenture does not place any limit on the amount of liabilities, including debt or preferred stock, that FPL Group Capital's subsidiaries may issue, guarantee or otherwise incur. See "Description of FPL Group Common Stock—Common Stock Terms—Dividend Rights" for a description of contractual restrictions on the dividend-paying ability of FPL Group Capital.

        While FPL Group is a holding company that derives substantially all of its income from its operating subsidiaries, FPL Group's subsidiaries are separate and distinct legal entities and, other than FPL Group Capital, have no obligation to make any payments on the FPL Group Subordinated Indenture Securities or to make any funds available for such payment. Therefore, FPL Group Subordinated Indenture Securities will effectively be subordinated to all indebtedness and other liabilities, including trade payables, debt and preferred stock, incurred or issued by FPL Group's

58



subsidiaries. In addition to trade liabilities, many of FPL Group's operating subsidiaries incur debt in order to finance their business activities. All of this indebtedness will effectively be senior to the FPL Group Subordinated Indenture Securities. The FPL Group Subordinated Indenture does not place any limit on the amount of liabilities, including debt or preferred stock, that FPL Group's subsidiaries may issue, guarantee or otherwise incur. See "Description of FPL Group Common Stock—Common Stock Terms—Dividend Rights" for a description of contractual restrictions on the dividend-paying ability of some of FPL Group's subsidiaries.

        Subordinated Guarantee of FPL Group Capital Junior Subordinated Debentures.    Pursuant to the Subordinated Guarantee, FPL Group will unconditionally and irrevocably guarantee the payment of principal of and any interest and premium, if any, on the FPL Group Capital Junior Subordinated Debentures, when due and payable, whether at the stated maturity date, by declaration of acceleration, call for redemption or otherwise, in accordance with the terms of such FPL Group Capital Junior Subordinated Debentures and the FPL Group Capital Subordinated Indenture. The Subordinated Guarantee will remain in effect until the entire principal of and any premium, if any, and interest on the FPL Group Capital Junior Subordinated Debentures has been paid in full or otherwise discharged in accordance with the provisions of the FPL Group Capital Subordinated Indenture. (FPL Group Capital Subordinated Indenture, Article Fourteen).

        The Subordinated Guarantee will be subordinate and junior in right of payment to all Senior Indebtedness of FPL Group. (FPL Group Capital Subordinated Indenture, Section 1402). No payment of the principal (including redemption and sinking fund payments) of, or interest, or premium, if any, on, the FPL Group Capital Junior Subordinated Debentures may be made by FPL Group under the Subordinated Guarantee until all holders of Senior Indebtedness of FPL Group have been paid in full (or provision has been made for such payment), if any of the following occurs:

        Upon any distribution of assets of FPL Group to creditors in connection with any insolvency, bankruptcy or similar proceeding, all principal of, and premium, if any, and interest due or to become due on all Senior Indebtedness of FPL Group must be paid in full before the holders of the FPL Group Capital Junior Subordinated Debentures are entitled to receive or retain any payment from such distribution. (FPL Group Capital Subordinated Indenture, Section 1403).

        While FPL Group is a holding company that derives substantially all of its income from its operating subsidiaries, FPL Group's subsidiaries are separate and distinct legal entities and have no obligation to make any payments under the Subordinated Guarantee or to make any funds available for such payment. Therefore, the Subordinated Guarantee will effectively be subordinated to all indebtedness and other liabilities, including trade payables, debt and preferred stock, incurred or issued by FPL Group's subsidiaries. In addition to trade liabilities, many of FPL Group's operating subsidiaries incur debt in order to finance their business activities. All of this indebtedness will effectively be senior to the Subordinated Guarantee. The FPL Group Capital Subordinated Indenture does not place any limit on the amount of liabilities, including debt or preferred stock, that FPL Group's subsidiaries may issue, guarantee or otherwise incur. See "Description of FPL Group Common Stock—Common Stock Terms—Dividend Rights" for a description of contractual restrictions on the dividend-paying ability of some of FPL Group's subsidiaries.

        Payment and Paying Agents.    Except as stated in the related prospectus supplement, on each interest payment date FPL Group Capital, or FPL Group, as the case may be, will pay interest on each Junior Subordinated Debenture to the person in whose name that Junior Subordinated Debenture is registered as of the close of business on the record date relating to that interest payment date. However, on the date that the Junior Subordinated Debentures mature, FPL Group Capital, or FPL Group, as the case may be, will pay the interest to the person to whom it pays the principal. Also, if FPL Group Capital, or FPL Group, as the case may be, has defaulted in the payment of interest on any Junior Subordinated Debenture, it may pay that defaulted interest to the registered owner of that Junior Subordinated Debenture:

        Unless otherwise stated in the related prospectus supplement, the principal, premium, if any, and interest on the Junior Subordinated Debentures at maturity will be payable when such Junior Subordinated Debentures are presented at the main corporate trust office of The Bank of New York Mellon, as paying agent, in The City of New York. FPL Group Capital and FPL Group with respect to the FPL Group Capital Junior Subordinated Debentures and FPL Group with respect to the FPL Group Junior Subordinated Debentures may change the place of payment on the Junior Subordinated Debentures, appoint one or more additional paying agents, including itself, and remove any paying agent. (Subordinated Indenture, Section 602).

        Transfer and Exchange.    Unless otherwise stated in the related prospectus supplement, Junior Subordinated Debentures may be transferred or exchanged at the main corporate trust office of The Bank of New York Mellon, as security registrar, in The City of New York. FPL Group Capital, or FPL Group, as the case may be, may change the place for transfer and exchange of the Junior Subordinated Debentures and may designate one or more additional places for that transfer and exchange.

        Except as otherwise stated in the related prospectus supplement, there will be no service charge for any transfer or exchange of the Junior Subordinated Debentures. However, FPL Group Capital, or FPL Group, as the case may be, may require payment of any tax or other governmental charge in connection with any transfer or exchange of the Junior Subordinated Debentures.

        FPL Group Capital, or FPL Group, as the case may be, will not be required to transfer or exchange any Junior Subordinated Debenture selected for redemption. Also, FPL Group Capital, or FPL Group, as the case may be, will not be required to transfer or exchange any Junior Subordinated Debenture during a period of 15 days before selection of Junior Subordinated Debentures to be redeemed. (Subordinated Indenture, Section 305).

        Unless otherwise stated in the related prospectus supplement, if Junior Subordinated Debentures are issued in connection with the issuance of Trust Securities and are subsequently distributed to holders of Preferred Trust Securities in a dissolution of the Trust, the Junior Subordinated Debentures will be issued in fully registered certificated form in the denominations and integral multiples thereof in which the Preferred Trust Securities have been issued, and they may be transferred or exchanged as described above. (Trust Agreement, Section 9.04).

        Defeasance.    FPL Group Capital and FPL Group may, at any time, elect to have all of their obligations discharged with respect to all or a portion of any Subordinated Indenture Securities of FPL Group Capital. FPL Group may, at any time, elect to have all of its obligations discharged with respect to all or a portion of any Subordinated Indenture Securities of FPL Group. To do so, FPL Group

60



Capital or FPL Group, with respect to FPL Group Capital Junior Subordinated Debentures, or FPL Group with respect to the FPL Group Junior Subordinated Debentures, must irrevocably deposit with the Subordinated Indenture Trustee or any paying agent, in trust:

        Option to Defer Interest Payments.    If so specified in the related prospectus supplement, FPL Group Capital, or FPL Group, as the case may be, will have the option to defer the payment of interest from time to time on the Junior Subordinated Debentures for one or more periods. In the event the Junior Subordinated Debentures are issued in connection with Preferred Trust Securities and FPL Group Capital, or FPL Group, as the case may be, decides to exercise the option to defer the payment of interest as provided in the related prospectus supplement, distributions on the Preferred Trust Securities would be deferred during any optional deferral period. Interest would, however, continue to accrue on the Junior Subordinated Debentures. Unless otherwise provided in the related prospectus supplement, during any optional deferral period, or for so long as an "Event of Default" under the Subordinated Indenture resulting from a payment default (or a payment default under the Preferred Trust Securities Guarantee if the Junior Subordinated Debentures are issued in connection with Preferred Trust Securities) has occurred and is continuing, neither FPL Group nor FPL Group Capital, with respect to FPL Group Capital Junior Subordinated Debentures, or FPL Group, with respect to FPL Group Junior Subordinated Debentures may:

61


62


        The exceptions in clauses (h) and (i) above are not applicable to an optional deferral period on the FPL Group Junior Subordinated Debentures.

        FPL Group and FPL Group Capital have reserved the right to amend the FPL Group Capital Subordinated Indenture, dated as of September 1, 2006, without the consent or action of the holders of any Subordinated Indenture Securities issued after October 1, 2006, including the Junior Subordinated Debentures, to modify the exceptions to the restrictions described in clause (f) above to allow payments with respect to any preferred trust securities or debt securities, or any guarantee thereof (including the Subordinated Guarantee), executed and delivered by FPL Group, FPL Group Capital or any of their subsidiaries, in each case that rank equal in right of payment to such junior subordinated debentures or the related guarantee, as the case may be, so long as the amount of payments made on account of such securities or guarantees is paid on all such securities or guarantees then outstanding on a pro rata basis in proportion to the full payment to which each series of such securities or guarantees is then entitled if paid in full.

        Unless otherwise provided in the related prospectus supplement, (i) before an optional deferral period ends, FPL Group Capital, or FPL Group, as the case may be, may further defer the payment of interest and (ii) after any optional deferral period and the payment of all amounts then due, FPL Group Capital, or FPL Group, as the case may be, may select a new optional deferral period. Unless otherwise provided in the related prospectus supplement, no optional deferral period may exceed the period of time specified in that prospectus supplement. No interest period may be deferred beyond the maturity of the Junior Subordinated Debentures. If the Junior Subordinated Debentures are issued in connection with Preferred Trust Securities, FPL Group Capital, or FPL Group, as the case may be, will give the Trust and the Subordinated Indenture Trustee notice of its election of an optional deferral period prior to the earlier of (i) one business day before the record date for the distribution on the Preferred Trust Securities which would occur if FPL Group Capital, or FPL Group, as the case may be, did not make the election to defer or (ii) the date the Administrative Trustees are required to give notice to any securities exchange or any other applicable self-regulatory organization of the record date for such a distribution. The Property Trustee shall send notice of that election to the holders of Preferred Trust Securities.

        Additional Interest.    If the Junior Subordinated Debentures are issued in connection with the issuance of Trust Securities and if the Trust is required to pay any taxes, duties, assessments or governmental charges imposed by the United States or any other taxing authority on income derived from the interest payments on the Junior Subordinated Debentures, then, so long as any Preferred Trust Securities remain outstanding, FPL Group Capital, or FPL Group, as the case may be, will pay as interest on the Junior Subordinated Debentures any additional interest that may be necessary in order that the net amounts received and retained by the Trust after the payment of those taxes, duties, assessments or governmental charges will be the same as the Trust would have had if such taxes, duties, assessments or other governmental charges had not been imposed. (Subordinated Indenture, Section 313).

        Redemption.    The redemption terms of the Junior Subordinated Debentures, if any, will be set forth in a prospectus supplement. Unless set forth differently in a prospectus supplement, and except with respect to Junior Subordinated Debentures redeemable at the option of the holder, Junior Subordinated Debentures will be redeemable upon notice between 30 and 60 days prior to the redemption date. If less than all of the Junior Subordinated Debentures of any series or any tranche thereof are to be redeemed, the Subordinated Indenture Trustee will select the Junior Subordinated Debentures to be redeemed. In the absence of any provision for selection, the Subordinated Indenture Trustee will choose a method of random selection as it deems fair and appropriate. (Subordinated Indenture, Sections 403 and 404).

63


        Junior Subordinated Debentures selected for redemption will cease to bear interest on the redemption date. The paying agent will pay the redemption price and any accrued interest once the Junior Subordinated Debentures are surrendered for redemption. (Subordinated Indenture, Section 405). If only part of a Junior Subordinated Debenture is redeemed, the Subordinated Indenture Trustee will deliver a new Junior Subordinated Debenture of the same series for the remaining portion without charge. (Subordinated Indenture, Section 406).

        Any redemption at the option of FPL Group Capital, or FPL Group, as the case may be, may be conditional upon the receipt by the paying agent, on or prior to the date fixed for redemption, of money sufficient to pay the redemption price. If the paying agent has not received such money by the date fixed for redemption, neither FPL Group Capital nor FPL Group, in the case of FPL Group Capital Junior Subordinated Debentures, nor FPL Group, in the case of FPL Group Junior Subordinated Debentures, will be required to redeem such Junior Subordinated Debentures. (Subordinated Indenture, Section 404).

        If the Junior Subordinated Debentures are issued in connection with the issuance of Trust Securities, for so long as the Trust is the holder of all of the related Junior Subordinated Debentures the proceeds of any redemption of Junior Subordinated Debentures will be used by the Trust to redeem Preferred Trust Securities and Common Trust Securities in accordance with their terms. (Trust Agreement, Section 4.02(a)).

        Subject to applicable law, including United States federal securities laws, FPL Group or its affiliates, including FPL Group Capital, may at any time and from time to time purchase outstanding Junior Subordinated Debentures by tender, in the open market or by private agreement.

        Consolidation, Merger, and Sale of Assets.    Under the FPL Group Capital Subordinated Indenture, neither FPL Group Capital nor FPL Group may, and under the FPL Group Subordinated Indenture, FPL Group may not, consolidate with or merge into any other entity or convey, transfer or lease its properties and assets substantially as an entirety to any entity, unless:

64


        Events of Default.    Each of the following is an event of default under the Subordinated Indenture with respect to the Subordinated Indenture Securities of any series:

65


        In the case of the third event of default listed above, the Subordinated Indenture Trustee may extend the grace period. In addition, if holders of a particular series have given a notice of default, then holders of at least the same percentage of Junior Subordinated Debentures of that series, together with the Subordinated Indenture Trustee, may also extend the grace period. The grace period will be automatically extended if FPL Group Capital or FPL Group, in the case of the FPL Group Capital Subordinated Indenture, or FPL Group, in the case of the FPL Group Subordinated Indenture, has initiated and is diligently pursuing corrective action in good faith. (Subordinated Indenture, Section 801). An event of default with respect to the Subordinated Indenture Securities of a particular series will not necessarily constitute an event of default with respect to Subordinated Indenture Securities of any other series issued under the Subordinated Indenture.

        Remedies.    If an event of default applicable to the Subordinated Indenture Securities of one or more series, but not applicable to all outstanding Subordinated Indenture Securities, exists, then either (i) the Subordinated Indenture Trustee or (ii) the registered owners of at least 33% in aggregate principal amount of the Subordinated Indenture Securities of each of the affected series may declare the principal of and accrued but unpaid interest on all the Subordinated Indenture Securities of that series to be due and payable immediately. (Subordinated Indenture, Section 802).

        If the event of default is applicable to all outstanding Subordinated Indenture Securities, then either (i) the Subordinated Indenture Trustee or (ii) the registered owners of at least 33% in aggregate principal amount of all outstanding Subordinated Indenture Securities of all series, voting as one class, and not the registered owners of any one series, may make a declaration of acceleration. (Subordinated Indenture, Section 802). However, the event of default giving rise to the declaration relating to any series of Subordinated Indenture Securities will be automatically waived, and that declaration and its consequences will be automatically rescinded and annulled, if, at any time after that declaration and before a judgment or decree for payment of the money due has been obtained:

        Other than its obligations and duties in case of an event of default under the Subordinated Indenture, the Subordinated Indenture Trustee is not obligated to exercise any of its rights or powers under the Subordinated Indenture at the request or direction of any of the registered owners of the Subordinated Indenture Securities, unless those registered owners offer reasonable indemnity to the Subordinated Indenture Trustee. (Subordinated Indenture, Section 903). If they provide this reasonable

66



indemnity, the registered owners of a majority in principal amount of any series of Subordinated Indenture Securities will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Subordinated Indenture Trustee, or exercising any trust or power conferred on the Subordinated Indenture Trustee, with respect to the Subordinated Indenture Securities of that series. However, if an event of default under the Subordinated Indenture relates to more than one series of Subordinated Indenture Securities, only the registered owners of a majority in aggregate principal amount of all affected series of Subordinated Indenture Securities, considered as one class, will have the right to make that direction. Also, the direction must not violate any law or the Subordinated Indenture, and may not expose the Subordinated Indenture Trustee to personal liability in circumstances where its indemnity would not, in the Subordinated Indenture Trustee's sole discretion, be adequate. (Subordinated Indenture, Section 812).

        A registered owner of a Subordinated Indenture Security has the right to institute a suit for the enforcement of payment of the principal of or premium, if any, or interest on that Subordinated Indenture Security on or after the applicable due date specified in that Subordinated Indenture Security. (Subordinated Indenture, Section 808). No registered owner of Subordinated Indenture Securities of any series will have any other right to institute any proceeding under the Subordinated Indenture, or exercise any other remedy under the Subordinated Indenture, unless:

        Each of FPL Group Capital and FPL Group in the case of the FPL Group Capital Subordinated Indenture, and FPL Group in the case of the FPL Group Subordinated Indenture, is required to deliver to the Subordinated Indenture Trustee an annual statement as to its compliance with all conditions and covenants applicable to it under the Subordinated Indenture. (Subordinated Indenture, Section 606).

        Enforcement of Certain Rights by Holders of Preferred Trust Securities.    If the Junior Subordinated Debentures were issued in connection with the issuance of Trust Securities and if there is an event of default with respect to Junior Subordinated Debentures held by the Trust, a holder of Preferred Trust Securities may enforce the Subordinated Indenture directly against FPL Group Capital in the case of the FPL Group Capital Subordinated Indenture, or FPL Group, in the case of the FPL Group Subordinated Indenture, to the same extent, and upon the same conditions, as if the holder of Preferred Trust Securities held a principal amount of Junior Subordinated Debentures equal to the aggregate liquidation amount of its Preferred Trust Securities. (Subordinated Indenture, Section 610).

67


        Subject to their right to bring suit to enforce their right to payment, the holders of Preferred Trust Securities would not be able to institute any proceeding with respect to the Subordinated Indenture unless the Subordinated Indenture Trustee has failed to do so for 60 days after a request of the holders of at least a majority of the aggregate liquidation amount of outstanding Preferred Trust Securities. Upon such failure, the holders of a majority of the aggregate liquidation amount of the outstanding Preferred Trust Securities would have the right to directly institute proceedings for enforcement of all other rights of the Subordinated Indenture Trustee against FPL Group Capital in the case of the FPL Group Capital Subordinated Indenture, or FPL Group in the case of the FPL Group Subordinated Indenture, to the fullest extent permitted by law. (Subordinated Indenture, Sections 807, 808 and 812).

        Modification and Waiver.    Without the consent of any registered owner of Subordinated Indenture Securities, FPL Group, the Subordinated Indenture Trustee and, in the case of the FPL Group Capital Subordinated Indenture, FPL Group Capital, may amend or supplement the Subordinated Indenture for any of the following purposes:

68


        The registered owners of a majority in aggregate principal amount of the Subordinated Indenture Securities of all series then outstanding may waive compliance by FPL Group Capital or FPL Group in the case of the FPL Group Capital Subordinated Indenture, or by FPL Group in the case of the FPL Group Subordinated Indenture, with certain restrictive provisions of the Subordinated Indenture. (Subordinated Indenture, Section 607). The registered owners of a majority in principal amount of the outstanding Subordinated Indenture Securities of any series may waive any past default under the Subordinated Indenture with respect to that series, except a default in the payment of principal, premium, if any, or interest and a default with respect to certain restrictive covenants or provisions of the Subordinated Indenture that cannot be modified or amended without the consent of the registered owner of each outstanding Subordinated Indenture Security of that series affected. (Subordinated Indenture, Section 813). If the Trust holds Subordinated Indenture Securities of any series, the Trust may not waive compliance, or any default in compliance, by FPL Group Capital or FPL Group with any covenant or term contained in, or any past default under, the Subordinated Indenture or the Subordinated Indenture Securities of such series, without the approval of at least a majority (or such greater percentage required by the Trust Agreement) in aggregate liquidation preference amount of the outstanding Preferred Trust Securities. (Subordinated Indenture, Sections 607 and 813).

        In addition to any amendments described above, if the Trust Indenture Act of 1939 is amended after the date of the Subordinated Indenture in a way that requires changes to the Subordinated Indenture or in a way that permits changes to, or the elimination of, provisions that were previously required by the Trust Indenture Act of 1939, the Subordinated Indenture will be deemed to be amended to conform to that amendment of the Trust Indenture Act of 1939 or to make those changes, additions or eliminations. FPL Group Capital and FPL Group in the case of the FPL Group Capital Subordinated Indenture, or FPL Group in the case of the FPL Group Subordinated Indenture, and the Subordinated Indenture Trustee may, without the consent of any registered owners, enter into supplemental indentures to make that amendment. (Subordinated Indenture, Section 1201).

        Except for any amendments described above, the consent of the registered owners of a majority in aggregate principal amount of the Subordinated Indenture Securities of all series then outstanding, considered as one class, is required for all other modifications to the Subordinated Indenture. However, if less than all of the series of Subordinated Indenture Securities outstanding are directly affected by a proposed supplemental indenture, then the consent only of the registered owners of a majority in aggregate principal amount of outstanding Subordinated Indenture Securities of all directly affected series, considered as one class, is required. But, if FPL Group Capital or FPL Group, as the case may be, issues any series of Subordinated Indenture Securities in more than one tranche and if the

69



proposed supplemental indenture directly affects the rights of the registered owners of Subordinated Indenture Securities of less than all of those tranches, then the consent only of the registered owners of a majority in aggregate principal amount of the outstanding Subordinated Indenture Securities of all directly affected tranches, considered as one class, will be required. However, none of those amendments or modifications may:

        A supplemental indenture that changes or eliminates any provision of the Subordinated Indenture that has expressly been included only for the benefit of one or more particular series or tranches of Subordinated Indenture Securities, or that modifies the rights of the registered owners of Subordinated Indenture Securities of that particular series or tranche with respect to that provision, will not affect the rights under the Subordinated Indenture of the registered owners of the Subordinated Indenture Securities of any other series or tranche. If Junior Subordinated Debentures were issued in connection with the issuance of Trust Securities, so long as any Preferred Trust Securities are outstanding, the Subordinated Indenture Trustee may not consent to any supplemental indenture without the prior consent of (i) the holders of a majority in aggregate liquidation preference of all outstanding Preferred Trust Securities affected or (ii), in the case of changes described in clauses (1) through (9) immediately above, 100% in aggregate liquidation preference of all such outstanding Preferred Trust Securities affected. (Subordinated Indenture, Section 1202).

70


        The Subordinated Indenture provides that, in order to determine whether the registered owners of the required principal amount of the outstanding Subordinated Indenture Securities have given any request, demand, authorization, direction, notice, consent or waiver under the Subordinated Indenture, or whether a quorum is present at the meeting of the registered owners of Subordinated Indenture Securities, (a) in the case of the FPL Group Capital Subordinated Indenture, Subordinated Indenture Securities owned by FPL Group Capital, FPL Group or any other obligor upon the Subordinated Indenture Securities or any affiliate of FPL Group Capital, FPL Group or of that other obligor (unless FPL Group Capital, FPL Group, that affiliate or that obligor owns all Subordinated Indenture Securities outstanding under the Subordinated Indenture, determined without regard to this provision) and (b) in the case of the FPL Group Subordinated Indenture, Subordinated Indenture Securities owned by FPL Group or any other obligor upon the Subordinated Indenture Securities or any affiliate of FPL Group or of that other obligor (unless FPL Group, that affiliate or that obligor owns all Subordinated Indenture Securities outstanding under the Subordinated Indenture, determined without regard to this provision), will be disregarded and deemed not to be outstanding. (Subordinated Indenture, Section 101).

        If FPL Group Capital or FPL Group, in the case of the FPL Group Capital Subordinated Indenture, or FPL Group, in the case of the FPL Group Subordinated Indenture, solicits any action under the Subordinated Indenture from registered owners of Subordinated Indenture Securities, each of FPL Group Capital or FPL Group in the case of the FPL Group Capital Subordinated Indenture, or FPL Group in the case of the FPL Group Subordinated Indenture, may, at its option, by signing a written request to the Subordinated Indenture Trustee, fix in advance a record date for determining the registered owners of Subordinated Indenture Securities entitled to take that action. However, neither FPL Group Capital nor FPL Group will be obligated to do this. If FPL Group Capital or FPL Group in the case of the FPL Group Capital Subordinated Indenture, or FPL Group in the case of the FPL Group Subordinated Indenture, as the case may be, fixes such a record date, that action may be taken before or after that record date, but only the registered owners of record at the close of business on that record date will be deemed to be registered owners of Subordinated Indenture Securities for the purposes of determining whether registered owners of the required proportion of the outstanding Subordinated Indenture Securities have authorized that action. For these purposes, the outstanding Subordinated Indenture Securities will be computed as of the record date. Any action of a registered owner of any Subordinated Indenture Security under the Subordinated Indenture will bind every future registered owner of that Subordinated Indenture Security, or any Subordinated Indenture Security replacing that Subordinated Indenture Security, with respect to anything that the Subordinated Indenture Trustee, FPL Group Capital or FPL Group in the case of the FPL Group Capital Subordinated Indenture, or the Subordinated Indenture Trustee or FPL Group in the case of the FPL Group Subordinated Indenture, do, fail to do, or allow to be done in reliance on that action, whether or not that action is noted upon that Subordinated Indenture Security. (Subordinated Indenture, Section 104).

        Resignation and Removal of Subordinated Indenture Trustee.    The Subordinated Indenture Trustee may resign at any time with respect to any series of Subordinated Indenture Securities by giving written notice of its resignation to FPL Group Capital and FPL Group in the case of the FPL Group Capital Subordinated Indenture, or FPL Group in the case of the FPL Group Subordinated Indenture. Also, the registered owners of a majority in principal amount of the outstanding Subordinated Indenture Securities of one or more series of Subordinated Indenture Securities may remove the Subordinated Indenture Trustee at any time with respect to the Subordinated Indenture Securities of that series, by delivering an instrument evidencing this action to the Subordinated Indenture Trustee, FPL Group Capital and FPL Group in the case of the FPL Group Capital Subordinated Indenture, and to the Subordinated Indenture Trustee and FPL Group in the case of the FPL Group Subordinated Indenture. However, if Junior Subordinated Debentures were issued in connection with the issuance of Trust Securities, so long as any Preferred Trust Securities remain outstanding, the Trust

71



cannot deliver an instrument evidencing this action without the consent of the holders of a majority in aggregate liquidation preference of Preferred Trust Securities outstanding. (Subordinated Indenture, Section 910). The resignation or removal of the Subordinated Indenture Trustee and the appointment of a successor trustee will not become effective until a successor trustee accepts its appointment.

        Except with respect to a Subordinated Indenture Trustee appointed by the registered owners of Subordinated Indenture Securities, the Subordinated Indenture Trustee will be deemed to have resigned and the successor will be deemed to have been appointed as trustee in accordance with the Subordinated Indenture if:

        Notices.    Notices to registered owners of Subordinated Indenture Securities will be sent by mail to the addresses of those registered owners as they appear in the security register for those Subordinated Indenture Securities. (Subordinated Indenture, Section 106).

        Title.    The person in whose name a Subordinated Indenture Security is registered may be treated as the absolute owner of that Subordinated Indenture Security, whether or not that Subordinated Indenture Security is overdue, for the purpose of making payments and for all other purposes, regardless of any notice to the contrary. (Subordinated Indenture, Section 308).

        Governing Law.    The Subordinated Indenture and the Subordinated Indenture Securities will be governed by, and construed in accordance with, the laws of the State of New York, without regard to conflict of laws principles thereunder, except to the extent that the law of any other jurisdiction is mandatorily applicable. (Subordinated Indenture, Section 112).

72

        This prospectus may be used in connection with any offering of securities through any of these methods or other methods described in the applicable prospectus supplement.

        Through Underwriters or Dealers.    If FPL Group, FPL Group Capital and/or the Trust uses underwriters in the sale of the Offered Securities, the underwriters will acquire the Offered Securities for their own account. The underwriters may resell the Offered Securities in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The underwriters may sell the Offered Securities directly or through underwriting syndicates represented by managing underwriters. Unless otherwise stated in the prospectus supplement relating to the Offered Securities, the obligations of the underwriters to purchase those Offered Securities will be subject to certain conditions, and the underwriters will be obligated to purchase all of those Offered Securities if they purchase any of them. If FPL Group, FPL Group Capital and/or the Trust uses a dealer in the sale, FPL Group, FPL Group Capital and/or the Trust will sell the Offered Securities to the dealer as principal. The dealer may then resell those Offered Securities at varying prices determined at the time of resale.

        Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

        Through Agents.    FPL Group, FPL Group Capital and/or the Trust may designate one or more agents to sell the Offered Securities. Unless otherwise stated in a prospectus supplement, the agents will agree to use their best efforts to solicit purchases for the period of their appointment.
