Company at a Glance

Tortoise Energy Infrastructure Corp. is a pioneering closed-end investment company investing primarily in equity securities of publicly-traded Master Limited Partnerships (MLPs) operating energy infrastructure assets.

Investment Goals: Yield, Growth and Quality

We seek a high level of total return with an emphasis on current distributions paid to stockholders.

In seeking to achieve yield, we target distributions to our stockholders that are roughly equal to the underlying yield on a direct investment in MLPs. In order to accomplish this, we maintain our strategy of investing primarily in energy infrastructure MLPs with attractive current yields and growth potential.

We seek to achieve distribution growth as revenues of our underlying companies grow with the economy, with the population and through rate increases. This revenue growth generally leads to increased operating profits, and when combined with internal expansion projects and acquisitions, is expected to provide attractive growth in distributions to us. We also seek distribution growth through capital market strategies involving timely debt and equity offerings by Tortoise Energy that are typically primarily invested in MLP issuer direct placements.

We seek to achieve quality by investing in companies operating energy infrastructure assets that are critical to the U.S. economy. Often these assets would be difficult to replicate. We also back experienced management teams with successful track records. By investing in Tortoise Energy, our stockholders have access to a portfolio that is diversified through geographic regions and across product lines, including natural gas, natural gas liquids, crude oil and refined products.

About Energy Infrastructure Master Limited Partnerships

MLPs are limited partnerships whose units trade on public exchanges such as the New York Stock Exchange (NYSE), the NYSE Alternext US and NASDAQ. Buying MLP units makes an investor a limited partner in the MLP. There are currently more than 70 MLPs in the market, mostly in industries related to energy and natural resources.

Tortoise Energy invests primarily in MLPs and their affiliates in the energy infrastructure sector. Energy infrastructure MLPs are engaged in the transportation, storage and processing of crude oil, natural gas and refined products from production points to the end users. Our investments are primarily in mid-stream (mostly pipeline) operations, which typically produce steady cash flows with less exposure to commodity prices than many alternative investments in the broader energy industry. With the growth potential of this sector along with our disciplined investment approach, we endeavor to generate a predictable and increasing distribution stream for our investors.

A Tortoise Energy Investment Versus a Direct Investment in MLPs

Tortoise Energy provides its stockholders an alternative to investing directly in MLPs and their affiliates. A direct MLP investment potentially offers an attractive distribution with a significant portion treated as return of capital, and a historically low correlation to returns on stocks and bonds. However, the tax characteristics of a direct MLP investment are generally undesirable for tax-exempt investors such as retirement plans. Tortoise Energy is structured as a C Corporation – accruing federal and state income taxes, based on taxable earnings and profits. Because of this innovative structure, pioneered by Tortoise Capital Advisors, institutions and retirement accounts are able to join individual stockholders as investors in MLPs.

Additional features of Tortoise Energy include:

One Form 1099 per stockholder at the end of the year, thus avoiding multiple K-1s and multiple state filings for individual partnership investments;
A professional management team, with nearly 100 years combined investment experience, to select and manage the portfolio on your behalf;
The ability to access investment grade credit markets to enhance stockholder return; and
Access to direct placements and other investments not available through the public markets.

Allocation of Portfolio Assets
May 31, 2009 (Unaudited)

June 30, 2009

Dear Fellow Stockholders,

Since the inception of TYG in February 2004, we have maintained that midstream MLPs should generate long-term returns of approximately 10 to 15 percent through a combination of yield, distribution growth and resulting capital appreciation. Over the past 10 years MLPs have achieved annual total returns of 14.2 percent.⁽¹⁾ However, during the 2008 stock market volatility, MLPs experienced exceptionally weak stock market returns, despite positive cash flow. While the MLP market has rebounded thus far in 2009, we believe MLPs remain undervalued compared to long-term spreads and cash flow multiples.

Master Limited Partnership Investment Overview and Outlook

For the quarter ended May 31, 2009, the MLP market, represented by the Wachovia MLP Index, reflected a total return of 21.2 percent compared to 6.1 percent for the prior quarter ended Feb. 28, 2009. The improved performance was driven primarily by resilient MLP business fundamentals, improved capital market access and a rebound from the 2008 sell off.

Our portfolio remains predominantly (approximately 82 percent) invested in long-haul interstate pipeline companies. These companies own interests or operate 150,000 miles of natural gas pipelines, 70,000 miles of petroleum pipelines and operate more than 400 refined product terminals. Without these essential assets, significant portions of our country would not have gasoline or diesel fuel to drive cars or trucks, jet fuel to fly planes or natural gas to heat homes or run electric generating facilities.

These essential assets have provided an attractive yield to investors and that yield has grown due to population growth, expansion projects and acquisitions. We believe those growth drivers should produce growth rates of 4 to 6 percent over the long-term, though growth will likely fall below these levels until the capital markets fully recover. Despite the potential for continued risk in the economy, we believe MLPs should prove more defensive and offer the security of steady distributions and attractive total return profiles versus other yield investments.

Performance Review

Our total return based on market value, including the reinvestment of distributions, was 25.2 percent for the quarter ended May 31, 2009, and 55.1 percent for the six months ended May 31, 2009.

We paid a distribution of $0.54 per common share ($2.16 annualized) to our stockholders on June 1, 2009, unchanged from the previous quarter. This represented an annualized yield of 8.5 percent based on the closing price of $25.28 on May 31, 2009. Based upon our current expectations, we believe our portfolio companies will continue to pay us distributions which will allow quarterly distributions to our stockholders of not less than $0.54 during fiscal year 2009.

On June 19, 2009, we entered into an amendment to our bank credit facility agreement that extends the facility through June 20, 2010. Terms of the amendment provide for an unsecured facility of $70 million. We currently have $18.9 million outstanding on our credit facility.

Additional information about our financial performance and use of leverage is available in the Management’s Discussion of this report.

Organizational Changes

On June 3, 2009, Tortoise Capital Advisors, L.L.C. (Tortoise) the adviser of Tortoise Energy Infrastructure Corp., announced that senior management of Tortoise entered into an agreement with Mariner Holdings, LLC (Mariner) to purchase all of the ownership interests in Tortoise owned by Kansas City Equity Partners (KCEP) and affiliates of KCEP and Fountain Capital Management. As part of the transaction, Mariner will purchase a majority stake in Tortoise, with the intention to provide growth capital and resources. With the provision of such growth capital and resources, Mariner will provide Tortoise with a complementary strategic partner in the asset management business.

The transaction is expected to close in the third calendar quarter of 2009 and is subject to the receipt of certain approvals, including the approval by TYG stockholders of a new investment advisory agreement with Tortoise, and the fulfillment of certain other conditions. A special meeting to vote on the matter has been scheduled for Sept. 11, 2009, and the proxy voting materials have been mailed. Our board has recommended that our stockholders approve the agreement and we encourage you to vote on this proposed agreement.

Conclusion

We maintain that our long-term thesis of yield, growth and quality remains fully intact. As of June 30, 2009, the Wachovia MLP Index yielded 9.3 percent. Combining that yield with a long-term growth rate of 4 to 6 percent implies long-term returns in the 10 to 15 percent range, and this comes from assets that are essential to providing basic energy products that the U.S. economy requires to successfully function.

We pride ourselves on having transparent and user-friendly investor information through our financial reports, our Web site and our Investor Relations services. As always, we welcome investor questions and comments and we thank you for your support of TYG.

Sincerely,

The Managing Directors
Tortoise Capital Advisors, L.L.C.

Management’s Discussion (Unaudited)

Management’s Discussion

The information contained in this section should be read in conjunction with our Financial Statements and the Notes thereto. In addition, this report contains certain forward-looking statements. These statements include the plans and objectives of management for future operations and financial objectives and can be identified by the use of forward-looking terminology such as “may,” “will,” “expect,” “intend,” “anticipate,” “estimate,” or “continue” or the negative thereof or other variations thereon or comparable terminology. These forward-looking statements are subject to the inherent uncertainties in predicting future results and conditions. Certain factors that could cause actual results and conditions to differ materially from those projected in these forward-looking statements are set forth in the “Risk Factors” section of our public filings with the SEC.

Overview

Tortoise Energy Infrastructure Corp’s goal is to provide a growing distribution stream to our investors. We seek to provide our stockholders with an efficient vehicle to invest in the energy infrastructure sector. While we are a registered investment company under the Investment Company Act of 1940, as amended (the “1940 Act”), we are not a “regulated investment company” for federal tax purposes. Our distributions do not typically generate unrelated business taxable income (UBTI) and our stock may therefore be suitable for holding by pension funds, IRAs and mutual funds, as well as taxable accounts. We invest primarily in MLPs through private and public market purchases. MLPs are publicly traded partnerships whose equity interests are traded in the form of units on public exchanges, such as the NYSE or NASDAQ.

Company Update

Market values of our MLP investments increased during 2nd quarter 2009 from their levels at February 28, 2009, having a positive impact on our capital structure and increasing the existing cushion on our leverage coverage ratios. We have entered into an amendment to our bank credit facility that extends through June 20, 2010. Additional information on our leverage is disclosed below and in our Notes to Financial Statements.

While we expect the current year to be challenging for almost every industry, including the energy infrastructure sector, we continue to believe the flow of energy commodities remains critical to our economy and that the long-term prospect for MLPs is attractive.

Critical Accounting Policies

The financial statements are based on the selection and application of critical accounting policies, which require management to make significant estimates and assumptions. Critical accounting policies are those that are both important to the presentation of our financial condition and results of operations and require management’s most difficult, complex, or subjective judgments. Our critical accounting policies are those applicable to the valuation of investments, tax matters and certain revenue recognition matters as discussed in Note 2 in the Notes to Financial Statements.

Determining Distributions to Stockholders

Our portfolio generates cash flow from which we pay distributions to stockholders. Our Board of Directors considers our distributable cash flow (“DCF”) in determining distributions to stockholders. Our Board of Directors reviews the distribution rate quarterly, and may adjust the quarterly distribution throughout the year. Our goal is to declare what we believe to be sustainable increases in our regular quarterly distributions. We have targeted to pay at least 95 percent of DCF on an annualized basis.

Determining DCF

DCF is simply distributions received from investments less expenses. The total distributions received from our investments include the amount received by us as cash distributions from MLPs, paid-in-kind distributions, and dividend and interest payments. The total expenses include current or anticipated operating expenses, leverage costs and current income taxes. Each are summarized for you in the table on page 2 and are discussed in more detail below.

The Key Financial Data table discloses the calculation of DCF and should be read in conjunction with this discussion. The difference between distributions received from investments in the DCF calculation and total investment income as reported in the Statement of Operations, is reconciled as follows: GAAP recognizes that a significant portion of the cash distributions received from MLPs are treated as a return of capital and therefore excluded from investment income, whereas the DCF calculation includes the return of capital; and distributions received from investments in the DCF calculation include the value of dividends paid-in-kind (additional stock or MLP units), whereas such amounts are not included as income for GAAP purposes. The treatment of expenses in the DCF calculation also differs from what is reported in the Statement of Operations. In addition to the total operating expenses as disclosed in the Statement of Operations, the DCF calculation reflects interest expense, recurring agent fees, distributions to preferred stockholders and realized and unrealized gains (losses) on interest rate swap settlements as leverage costs, as well as current taxes paid.

Distributions Received from Investments

Our ability to generate cash is dependent on the ability of our portfolio of investments to generate cash flow from their operations. In order to maintain and grow distributions to our stockholders, we evaluate each holding based upon its contribution to our investment income, our expectation for its growth rate, and its risk relative to other potential investments.

We concentrate on MLPs we believe can expect an increasing demand for services from economic and population growth. We seek well-managed businesses with hard assets and stable recurring revenue streams. Our focus remains primarily on investing in fee-based service providers that operate long-haul, interstate pipelines. We further diversify among issuers, geographies and energy commodities to seek a distribution payment which approximates an investment directly in energy infrastructure MLPs. In addition, most energy infrastructure companies are regulated and utilize an inflation escalator index that factors in inflation as a cost pass-through. So, over the long-term, we believe MLPs’ distributions will outpace inflation and interest rate increases, and produce positive returns. However, during the last year the economy has been retrenching which may lead some MLPs to slow distribution growth or possibly reduce distributions.

Total distributions received from our investments for the 2nd quarter 2009 was approximately $19.3 million, representing a 10 percent decrease as compared to 2nd quarter 2008 and a 1 percent increase as compared to 1st quarter 2009. These changes reflect the result of net portfolio sales over the last 12 months and net distribution increases from our MLP investments.

Expenses

We incur two types of expenses: (1) operating expenses, consisting primarily of the advisory fee; and (2) leverage costs. On a percentage basis, operating expenses before leverage costs and current taxes were an annualized 1.09 percent of average total assets for the 2nd quarter 2009 as compared to 0.96 percent for the 2nd quarter 2008 and 0.99 percent for the 1st quarter 2009. Advisory fees for the 2nd quarter 2009 increased 25 percent from 1st quarter 2009 as a result of increased average managed assets from increasing MLP asset values and the expiration of the 0.10 percent expense reimbursement. If yields on our MLP investments continue to revert more to their historical norm, all else being equal, MLP asset values will increase as will our managed assets and advisory fees. Other operating expenses were relatively unchanged as compared to 1st quarter 2009.

Leverage costs consist of four major components: (1) the direct interest expense on our Tortoise Notes and short-term credit facility; (2) the agent fees, which are the marketing and rating agency costs for the leverage; (3) the realized and unrealized gain or loss on interest rate swap settlements (if any); and (4) distributions to preferred stockholders.

Total leverage costs for DCF purposes were approximately $4.0 million for the 2nd quarter 2009 as compared to $8.1 million for the 2nd quarter 2008 and $4.0 million for the 1st quarter 2009, as detailed below.

2009 2nd Quarter Report

Management’s Discussion (Unaudited)
(Continued)

The decrease in total leverage costs from 2nd quarter 2008 to 2nd quarter 2009 reflects the reduction in average outstanding leverage of approximately $180 million during the period. The average annualized total cost of leverage (total leverage costs divided by average outstanding leverage) was 6.16 percent for the 2nd quarter 2009 as compared to 6.17 percent for the 1st quarter 2009, and 7.30 percent for 2nd quarter 2008.

Our effective cost of fixed-rate leverage as of May 31, 2009 was 6.40 percent including the $170 million aggregate Series A and E Notes (rates fixed into 2012 and 2015, respectively), $70 million notional amount of outstanding auction rate preferred shares (rates fixed through August 2010), and agent fees. This rate does not include balances on our bank line of credit which accrues interest at a variable rate equal to one-month LIBOR plus 2.00 percent. At May 31, 2009, approximately 97 percent of our leverage was at a fixed rate. Our all-in financing rate may vary in future periods as Notes are redeemed or mature, or extended auction rate leverage is reset or refinanced. Additional information on our leverage is disclosed below in Liquidity and Capital Resources and in our Notes to Financial Statements.

Distributable Cash Flow

For 2nd quarter 2009, our DCF was approximately $13.1 million, an increase of 27 percent as compared to 2nd quarter 2008 and a decrease of 2 percent as compared to 1st quarter 2009. The increase from 2nd quarter 2008 is the net result of lower total distributions received from investments which were more than offset by reduced expenses, primarily advisory fees and leverage costs. The decrease from 1st quarter 2009 reflects an increase in distributions received from investments offset by an increase in asset-based advisory fees. We paid a distribution of $12.7 million, or 96.3 percent of DCF, during the quarter. On a per share basis, we declared a $0.54 distribution on May 12, 2009. This is a decrease of $0.0175 or 3.1 percent as compared to 2nd quarter 2008 and unchanged from 1st quarter 2009.

Factoring in portfolio sales in fiscal year 2008 to fund leverage reductions and assuming moderate to no increases in projected distribution income from MLPs and our cost of leverage, we currently expect to pay quarterly distributions to our stockholders of not less than $0.54 per share during the remainder of fiscal year 2009. This represents a current estimate and is subject to change based upon actual results and Board approval.

Liquidity and Capital Resources

We had total assets of $840 million at quarter-end. Our total assets reflect the value of our investments, which are itemized in the Schedule of Investments. It also reflects cash, interest and other receivables and any expenses that may have been prepaid. During 2nd quarter 2009, total assets increased from approximately $719 million to $840 million, an increase of $121 million. This change was primarily the result of an increase in unrealized appreciation of investments of approximately $135 million during the quarter (excluding return of capital on distributions during the quarter) and the use of $13 million in cash to redeem short-term borrowings.

Total leverage outstanding at May 31, 2009 of approximately $247.5 million is comprised of $170 million in senior notes, $70 million in preferred shares and $7.5 million outstanding under the credit facility. Total leverage represented 29.5 percent of total assets at May 31, 2009, slightly below our target ratio of 33 percent and a decrease of 6.7 percent as compared to February 28, 2009. Our leverage ratio is impacted by increases or decreases in MLP values, issuance of equity and/or the sale of securities where proceeds are used to reduce leverage.

Subsequent to quarter-end, we entered into an amendment to our bank credit facility that extends the facility through June 20, 2010. Terms of the amendment provide for an unsecured facility of $70 million. During the extension, outstanding balances generally will accrue interest at a variable rate equal to one-month LIBOR plus 2.00 percent with a fee of 0.25 percent on any unused balance.

We have used leverage to acquire MLPs consistent with our investment philosophy. The terms of our leverage are governed by regulatory and contractual asset coverage requirements that arise from the use of leverage. Under the 1940 Act, we may not pay distributions to our common stockholders if we do not meet a 300 percent asset coverage ratio for debt and 200 percent asset coverage ratio for debt and preferred shares after payment of the distribution, and we may not pay distributions on our preferred shares if we fail to meet a 200 percent asset coverage ratio on our debt. Under the agreement with our bank lenders, if portfolio values decline such that we no longer meet the asset coverage ratios under the 1940 Act, we must repay a portion of our bank line until we meet the coverage requirement. Further, under the terms of our institutional senior notes and preferred shares, if we fail to meet basic maintenance ratios as of any valuation date (generally Fridays) or fail to satisfy the 1940 Act asset coverage as of the last business day of any month, we could be subject to mandatory redemption of the senior notes or preferred shares if such failure is not waived or cured. In some cases we may be delayed in paying common stock or preferred share distributions until such coverage ratios can be met.

As disclosed in Section 18 of the 1940 Act, the 300 percent asset coverage ratio for debt is equal to total assets less all liabilities and indebtedness not represented by debt divided by debt. The 200 percent asset coverage ratio for preferred shares is equal to the same numerator as the 300 percent test divided by the sum of debt and preferred shares. Deferred tax assets are a component of total assets in calculation of these ratios. Our coverage ratios are currently updated each week and available on our web site at www.tortoiseadvisors.com.

Taxation of our Distributions and Deferred Taxes

We invest in partnerships which generally have larger distributions of cash than the accounting income which they generate. Accordingly, the distributions include a return of capital component for accounting and tax purposes. Distributions declared and paid by us in a year generally differ from taxable income for that year, as such distributions may include the distribution of current year taxable income or return of capital.

The taxability of the distribution you receive depends on whether we have annual earnings and profits. If so, those earnings and profits are first allocated to the preferred shares and then to the common shares.

In the event we have earnings and profits allocated to our common shares, all or a portion of our distribution will be taxable at the 15 percent Qualified Dividend Income (“QDI”) rate, assuming various holding requirements are met by the stockholder. The portion of our distribution that is taxable may vary for either of two reasons: first, the characterization of the distributions we receive from MLPs could change annually based upon the K-1s we receive and become less return of capital and more in the form of income. Second, we could sell an MLP investment and realize a gain or loss at any time. It is for these reasons that we inform you of the tax treatment after the close of each year as the ultimate result is undeterminable until the year is over.

For book and tax purposes, distributions to stockholders for the fiscal year ended 2008 were comprised of 100 percent return of capital. We currently expect that a substantial portion of our 2009 distributions will consist of return of capital, although the ultimate determination will not be made until January 2010, after determining our earnings and profits.

The unrealized gain or loss we have in the portfolio is reflected in the Statement of Assets and Liabilities. At May 31, 2009, our investments at value are $836 million, with an adjusted cost of $648 million. The $188 million difference reflects unrealized appreciation that would be realized for financial statement purposes if those investments were sold at those values.

NOTES TO FINANCIAL STATEMENTS (Unaudited)
May 31, 2009

1. Organization

Tortoise Energy Infrastructure Corporation (the “Company”) was organized as a Maryland corporation on October 29, 2003, and is a non-diversified, closed-end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). The Company’s investment objective is to seek a high level of total return with an emphasis on current distributions paid to stockholders. The Company seeks to provide its stockholders with an efficient vehicle to invest in the energy infrastructure sector. The Company commenced operations on February 27, 2004. The Company’s stock is listed on the New York Stock Exchange under the symbol “TYG.”

2. Significant Accounting Policies

A. Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amount of assets and liabilities, recognition of distribution income and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.

B. Investment Valuation

The Company primarily owns securities that are listed on a securities exchange or over-the-counter market. The Company values those securities at their last sale price on that exchange or over-the-counter market on the valuation date. If the security is listed on more than one exchange, the Company will use the price from the exchange that it considers to be the principal exchange on which the security is traded. Securities listed on the NASDAQ will be valued at the NASDAQ Official Closing Price, which may not necessarily represent the last sale price. If there has been no sale on such exchange or over-the-counter market on such day, the security will be valued at the mean between the bid and ask price on such day.

The Company may invest up to 30 percent of its total assets in restricted securities. Restricted securities are subject to statutory or contractual restrictions on their public resale, which may make it more difficult to obtain a valuation and may limit the Company’s ability to dispose of them. Investments in private placement securities and other securities for which market quotations are not readily available will be valued in good faith by using fair value procedures approved by the Board of Directors. Such fair value procedures consider factors such as discounts to publicly traded issues, time until conversion date, securities with similar yields, quality, type of issue, coupon, duration and rating. If events occur that will affect the value of the Company’s portfolio securities before the net asset value has been calculated (a “significant event”), the portfolio securities so affected will generally be priced using a fair value procedure.

An equity security of a publicly traded company acquired in a direct placement transaction may be subject to restrictions on resale that can affect the security’s liquidity and fair value. Such securities that are convertible into or otherwise will become freely tradable will be valued based on the market value of the freely tradable security less an applicable discount. Generally, the discount will initially be equal to the discount at which the Company purchased the securities. To the extent that such securities are convertible or otherwise become freely tradable within a time frame that may be reasonably determined, an amortization schedule may be used to determine the discount.

The Company determines fair value in accordance with Statement of Financial Accounting Standards No. 157, Fair Value Measurements (“SFAS 157”). SFAS 157 defines fair value, establishes a framework for measuring fair value in accordance with U.S. generally accepted accounting principles and expands disclosures about fair value measurements. SFAS 157 is applicable in conjunction with other accounting pronouncements that require or permit fair value measurements, but does not expand the use of fair value to any new circumstances. More specifically, SFAS 157 emphasizes that fair value is a market based measurement, not an entity-specific measurement, and sets out a fair value hierarchy with the highest priority given to quoted prices in active markets and the lowest priority to unobservable inputs. See Note 6 — Fair Value of Financial Instruments for further disclosure.

The Company generally values short-term debt securities at prices based on market quotations for such securities, except those securities purchased with 60 days or less to maturity are valued on the basis of amortized cost, which approximates market value.

C. Security Transactions and Investment Income

Security transactions are accounted for on the date the securities are purchased or sold (trade date). Realized gains and losses are reported on an identified cost basis. Interest income is recognized on the accrual basis, including amortization of premiums and accretion of discounts. Dividends and distribution income is recorded on the ex-dividend date. Distributions received from the Company’s investments in master limited partnerships (“MLPs”) generally are comprised of ordinary income, capital gains and return of capital from the MLPs. The Company allocates distributions between investment income and return of capital based on estimates made at the time such distributions are received. Such estimates are based on historical information available from each MLP and other industry sources. These estimates may subsequently be revised based on actual allocations received from MLPs after their tax reporting periods are concluded, as the actual character of these distributions is not known until after the fiscal year end of the Company.

For the period from December 1, 2007 through November 30, 2008, the Company estimated the allocation of investment income and return of capital for the distributions received from MLPs within the Statement of Operations. For this period, the Company had estimated approximately 13 percent of total distributions as investment income and approximately 87 percent as return of capital.

Subsequent to November 30, 2008, the Company reallocated the amount of investment income and return of capital it recognized based on the 2008 tax reporting information received from the individual MLPs. This reallocation amounted to an increase in pre-tax net investment income of approximately $4,674,000 or $0.200 per share ($2,867,000 or $0.122 per share, net of deferred tax expense); a decrease in unrealized appreciation of investments of approximately $4,961,000 or $0.212 per share ($3,043,000 or $0.130 per share, net of deferred tax benefit) and an increase in realized gains of approximately $287,000 or $0.012 per share ($176,000 or $0.008 per share, net of deferred tax expense) for the period from December 1, 2008 through May 31, 2009.

Subsequent to the period ended February 28, 2009, the Company reallocated the amount of investment income and return of capital reported in the current fiscal year based on its revised 2009 estimates. This reallocation amounted to a decrease in pre-tax net investment income of approximately $134,000 or $0.006 per share ($82,000 or $0.003 per share, net of deferred tax benefit); an increase in unrealized appreciation of investments of approximately $1,301,000 or $0.056 per share ($798,000 or $0.034 per share, net of deferred tax expense) and a decrease in realized gains of approximately $1,168,000 or $0.050 per share ($716,000 or $0.031 per share, net of deferred tax benefit).

D. Distributions to Stockholders

Distributions to common stockholders are recorded on the ex-dividend date. The Company may not declare or pay distributions to its common stockholders if it does not meet asset coverage ratios required under the 1940 Act or the rating agency guidelines for its debt and preferred stock following such distribution. The character of distributions to common stockholders made during the year may differ from their ultimate characterization for federal income tax purposes. For the year ended November 30, 2008 and the period ended May 31, 2009, the Company’s distributions to common stockholders for book purposes were comprised of 100 percent return of capital. For the year ended November 30, 2008, the Company’s distributions to common stockholders for tax purposes were comprised of 100 percent return of capital.

2009 2nd Quarter Report 11

NOTES TO FINANCIAL STATEMENTS (Unaudited)
(Continued)

The tax character of distributions paid for the current year will be determined subsequent to November 30, 2009.

Distributions to preferred stockholders are based on variable rates set at auctions, normally held every 28 days unless a special rate period is designated. The Company may not declare or pay distributions to its preferred stockholders if it does not meet a 200 percent asset coverage ratio for its debt or the rating agency basic maintenance amount for the debt following such distribution. Distributions to preferred stockholders are accrued on a daily basis for the subsequent rate period at a rate determined on the auction date. Distributions to preferred stockholders are payable on the first day following the end of the rate period or the first day of the month if the rate period is longer than one month. For the year ended November 30, 2008 and the period ended May 31, 2009, the Company’s distributions to preferred stockholders for book purposes were comprised of 100 percent return of capital. The tax character of distributions paid for the current year will be determined subsequent to November 30, 2009.

E. Federal Income Taxation

The Company, as a corporation, is obligated to pay federal and state income tax on its taxable income. Currently, the highest regular marginal federal income tax rate for a corporation is 35 percent; however, the Company anticipates a marginal effective rate of 34.5 percent due to expectations of the level of taxable income relative to the federal graduated tax rates, including the tax rate anticipated when temporary differences reverse. The Company may be subject to a 20 percent federal alternative minimum tax on its federal alternative minimum taxable income to the extent that its alternative minimum tax exceeds its regular federal income tax.

The Company invests its assets primarily in MLPs, which generally are treated as partnerships for federal income tax purposes. As a limited partner in the MLPs, the Company reports its allocable share of the MLP’s taxable income in computing its own taxable income. The Company’s tax expense or benefit is included in the Statement of Operations based on the component of income or gains (losses) to which such expense or benefit relates. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. A valuation allowance is recognized if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred income tax asset will not be realized.

F. Organization Expenses, Offering and Debt Issuance Costs

The Company is responsible for paying all organizational expenses, which were expensed as incurred. Offering costs related to the issuance of common and preferred stock are charged to additional paid-in capital when the stock is issued. Debt issuance costs related to long-term debt obligations are capitalized and amortized over the period the debt is outstanding. Offering costs of $9,059 related to the issuance of common stock in September 2008 were recorded to additional paid-in capital during the period ended May 31, 2009.

G. Derivative Financial Instruments

The Company may use derivative financial instruments (principally interest rate swap contracts) in an attempt to manage interest rate risk. The Company has established policies and procedures for risk assessment and the approval, reporting and monitoring of derivative financial instrument activities. The Company does not hold or issue derivative financial instruments for speculative purposes. All derivative financial instruments are recorded at fair value with changes in fair value during the reporting period and amounts accrued under the derivative instruments included as unrealized gains or losses in the accompanying Statement of Operations. Monthly cash settlements under the terms of the derivative instruments and the termination of such contracts are recorded as realized gains or losses in the accompanying Statement of Operations.

H. Indemnifications

Under the Company’s organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the Company. In addition, in the normal course of business, the Company may enter into contracts that provide general indemnification to other parties. The Company’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Company that have not yet occurred, and may not occur. However, the Company has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

I. Recent Accounting Pronouncements

On April 9, 2009, the FASB issued Staff Position No. 157-4, Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly (“FSP 157-4”). FSP 157-4 provides additional guidance for estimating fair value in accordance with SFAS 157 when the volume and level of activity for the asset or liability have significantly decreased. FSP 157-4 also provides guidance on identifying circumstances that indicate a transaction is not orderly. FSP 157-4 is effective for interim and annual reporting periods ending after June 15, 2009. The adoption of FSP 157-4 is not expected to have a significant impact on the Company’s financial statements.

On April 9, 2009, the FASB issued FASB Staff Position (FSP) No. FAS 107-1 and APB 28-1, Interim Disclosures about Fair Value of Financial Instruments, which amends FASB Statement No. 107, Disclosures about Fair Value of Financial Instruments (“FSP 107-1”), to require disclosures about fair value of financial instruments for interim financial statements of publicly traded companies as well as in annual financial statements. FSP 107-1 also amends APB Opinion No. 28, Interim Financial Reporting, to require those disclosures in summarized financial information at interim reporting periods. FSP 107-1 is effective for interim reporting periods ending after June 15, 2009. The adoption of FSP 107-1 is not expected to have a significant impact on the Company’s financial statements.

3. Concentration of Risk

The Company’s investment objective is to seek a high level of total return with an emphasis on current distributions paid to its stockholders. Under normal circumstances, the Company intends to invest at least 90 percent of its total assets in securities of energy infrastructure companies, and to invest at least 70 percent of its total assets in equity securities of MLPs. The Company will not invest more than 10 percent of its total assets in any single issuer as of the time of purchase. The Company may invest up to 25 percent of its assets in debt securities, which may include below investment grade securities. In determining application of these policies, the term “total assets” includes assets obtained through leverage. Companies that primarily invest in a particular sector may experience greater volatility than companies investing in a broad range of industry sectors. The Company may, for defensive purposes, temporarily invest all or a significant portion of its assets in investment grade securities, short-term debt securities and cash or cash equivalents. To the extent the Company uses this strategy, it may not achieve its investment objective.

4. Agreements

The Company has entered into an Investment Advisory Agreement with Tortoise Capital Advisors, L.L.C. (the “Adviser”). Under the terms of the agreement, the Company pays the Adviser a fee equal to an annual rate of 0.95 percent of the Company’s average monthly total assets (including any assets attributable to leverage and excluding any net deferred tax asset) minus accrued liabilities (other than net deferred tax liability, debt entered into for purposes of leverage and the aggregate liquidation preference of outstanding preferred stock) (“Managed Assets”), in exchange for the investment advisory services provided. For the period from March 1, 2006 through February 28, 2009, the Adviser

12 Tortoise Energy Infrastructure Corp.

NOTES TO FINANCIAL STATEMENTS (Unaudited)
(Continued)

waived fees in an amount equal to 0.10 percent of the average monthly Managed Assets of the Company.

The Company has engaged U.S. Bancorp Fund Services, LLC to serve as the Company’s administrator. The Company pays the administrator a monthly fee computed at an annual rate of 0.04 percent of the first $1,000,000,000 of the Company’s Managed Assets, 0.03 percent on the next $1,000,000,000 of Managed Assets and 0.02 percent on the balance of the Company’s Managed Assets.

Computershare Trust Company, N.A. serves as the Company’s transfer agent, dividend paying agent, and agent for the automatic dividend reinvestment and cash purchase plan.

U.S. Bank, N.A. serves as the Company’s custodian. The Company pays the custodian a monthly fee computed at an annual rate of 0.015 percent on the first $100,000,000 of the Company’s portfolio assets and 0.01 percent on the balance of the Company’s portfolio assets.

5. Income Taxes

Deferred income taxes reflect the net tax effect of temporary differences between the carrying amount of assets and liabilities for financial reporting and tax purposes. Components of the Company’s deferred tax assets and liabilities as of May 31, 2009, are as follows:

Deferred tax assets:
Net operating loss carryforwards	$	23,936,851
Capital loss carryforwards		17,500,456
Deferred expense associated with interest rate swap terminations		1,709,958
Accrued expenses		2,120,623
Alternative minimum tax credit carryforward		67,228
		45,335,116
Deferred tax liabilities:
Basis reduction of investment in MLPs		35,664,062
Net unrealized gains on investment securities		69,073,787
		104,737,849
Total net deferred tax liability	$	59,402,733

At May 31, 2009, a valuation allowance on deferred tax assets was not deemed necessary because the Company believes it is more likely than not that there is an ability to realize its deferred tax assets based on the Company’s estimates of the timing of the reversal of deferred tax liabilities. Any adjustments to such estimates will be made in the period such determination is made. The Company’s policy is to record interest and penalties on uncertain tax positions as part of tax expense. No interest or penalties were accrued at May 31, 2009. The tax years ending November 30, 2005 and later remain open to examination by federal and state tax authorities.

Total income tax expense differs from the amount computed by applying the federal statutory income tax rate of 34.5 percent to net investment loss and realized loss and unrealized gains for the period ended May 31, 2009, as follows:

Application of statutory income tax rate	$	73,466,880
State income taxes, net of federal tax benefit		8,837,320
Foreign taxes, net of federal tax benefit		(326,879	)
Change in state income taxes, including reserve for
unrecognized tax benefits for state income taxes		(72,806	)
Total income tax expense	$	81,904,515

Total income taxes are computed by applying the federal statutory rate plus a blended state income tax rate. During the period, the Company re-evaluated its overall federal and state income tax rate, increasing it from 36.77 percent to 38.65 percent, primarily due to the reserve for unrecognized tax benefits.

For the period from December 1, 2008 to May 31, 2009, the components of income tax expense include current foreign tax benefit (for which the federal tax effect is reflected in deferred tax expense) of $532,810, current federal and state income tax expense (net of federal tax benefit) of $5,486,734 and $659,998, respectively, and deferred federal and state income tax expense (net of federal tax benefit) of $68,098,977 and $8,191,616, respectively.

As of November 30, 2008, the Company had a net operating loss for federal income tax purposes of approximately $46,840,000. The net operating loss may be carried forward for 20 years. If not utilized, this net operating loss will expire as follows: $2,883,000, $15,979,000, $22,275,000, $1,067,000 and $4,636,000 in the years ending November 30, 2024, 2025, 2026, 2027 and 2028, respectively. As of November 30, 2008, the Company had a capital loss carryforward of approximately $42,900,000, which may be carried forward 5 years and if not utilized expires in the year ending November 30, 2013. The amount of the deferred tax asset for these items at May 31, 2009 also includes amounts for the period from December 1, 2008 through May 31, 2009. For corporations, capital losses can only be used to offset capital gains and cannot be used to offset ordinary income. As of November 30, 2008, an alternative minimum tax credit of $67,228 was available, which may be credited in the future against regular income tax. This credit may be carried forward indefinitely.

As of May 31, 2009, the aggregate cost of securities for federal income tax purposes was $551,116,891. At May 31, 2009, the aggregate gross unrealized appreciation for all securities in which there was an excess of fair value over tax cost was $310,315,407, the aggregate gross unrealized depreciation for all securities in which there was an excess of tax cost over fair value was $25,615,989 and the net unrealized appreciation was $284,699,418.

6. Fair Value of Financial Instruments

Various inputs are used in determining the value of the Company’s investments. These inputs are summarized in the three broad levels listed below:

	Level 1 —		quoted prices in active markets for identical investments

	Level 2 —		other significant observable inputs (including quoted prices for similar investments, market corroborated inputs, etc.)

	Level 3 —		significant unobservable inputs (including the Company’s own assumptions in determining the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following table provides the fair value measurements of applicable Company assets by level within the fair value hierarchy as of May 31, 2009. These assets are measured on a recurring basis.

		Fair Value Measurements at Reporting Date Using
		Quoted Prices in		Significant
		Active Markets for	Significant Other	Unobservable

2009 2nd Quarter Report 13

NOTES TO FINANCIAL STATEMENTS (Unaudited)
(Continued)

The Company utilizes the beginning of reporting period method for determining transfers into or out of Level 3. Accordingly, this method is the basis for presenting the rollforward in the preceding table. Under this method, the fair value of the asset at the beginning of the period will be disclosed as a transfer into or out of Level 3, gains or losses for an asset that transfers into Level 3 during the period will be included in the reconciliation, and gains or losses for an asset that transfers out of Level 3 will be excluded from the reconciliation.

7. Restricted Securities

Certain of the Company’s investments are restricted and are valued as determined in accordance with procedures established by the Board of Directors, as more fully described in Note 2. The table below shows the number of units held, acquisition date, acquisition cost, fair value per share and percent of net assets which the securities comprise at May 31, 2009.

						Fair		Fair
						Value		Value as
		Number	Acquisition	Acquisition		Per		Percent of

				$	57,500,675				9.8	%

8. Investment Transactions

For the period ended May 31, 2009, the Company purchased (at cost) and sold securities (proceeds received) in the amount of $51,568,911 and $57,453,887 (excluding short-term debt securities), respectively.

9. Long-Term Debt Obligations

The Company has $60,000,000 aggregate principal amount of auction rate senior notes (Series A) and $110,000,000 aggregate principal amount of private senior notes (Series E), (collectively, the “Notes”) outstanding. Holders of the auction rate senior notes are entitled to receive cash interest payments at an annual rate that may vary for each rate period as determined by the auction. In the event that there are not enough bidders in the auction at rates below the maximum rate as prescribed by the terms of the Series A Notes, the auction fails. When an auction fails, the rate paid to continuing or new bidders is set at the maximum rate. A failed auction does not cause an acceleration of, or otherwise have any impact on, outstanding principal amounts due or affect the security’s liquidation preference. In the event of a failed auction, interest continues to be paid at the maximum rates and times determined in the indenture. The maximum rate based on the Series A Notes’ current ratings is 200 percent of the greater of: (i) the applicable AA Composite Commercial Paper Rate or the applicable Treasury Index Rate or (ii) the applicable LIBOR as of the date of the auction.

The Notes are unsecured obligations of the Company and, upon liquidation, dissolution or winding up of the Company, will rank: (1) senior to all of the Company’s outstanding preferred shares; (2) senior to all of the Company’s outstanding common shares; (3) on parity with any unsecured creditors of the Company and any unsecured senior securities representing indebtedness of the Company and (4) junior to any secured creditors of the Company.

The Notes are redeemable in certain circumstances at the option of the Company. The Notes are also subject to a mandatory redemption if the Company fails to meet asset coverage ratios required under the 1940 Act or the rating agency guidelines if such failure is not waived or cured. At May 31, 2009, the Company was in compliance with asset coverage covenants and basic maintenance covenants for its senior notes.

On December 3, 2008, the Company partially redeemed its Series E Notes in the amount of $40,000,000. The Company paid a premium and fees upon redemption of $800,000 and $80,000, respectively. The unamortized balance of allocated capital costs was expensed and resulted in a loss on early redemption in the amount of $134,000, which is included in amortization of debt issuance costs in the accompanying Statement of Operations.

Estimated fair value of the Series A and Series E Notes was calculated using the spread between the AAA corporate finance debt rate and the U.S. Treasury rate with an equivalent maturity date plus the average spread between the current rates of the Notes and the AAA corporate finance debt rate. At May 31, 2009, the total spread was applied to the equivalent U.S. Treasury rate for each series and future cash flows were discounted to determine estimated fair value. The following table shows the maturity date, notional/ carrying amount, estimated fair value, current rate as of May 31, 2009, the weighted-average rate for the period ended May 31, 2009 and the typical rate period for each series of Notes outstanding at May 31, 2009. The Company may designate a rate period that is different than the rate period indicated in the following table.

			Notional/					Weighted-
	Maturity		Carrying		Estimated	Current		Average
Series	Date		Amount		Fair Value	Rate		Rate	Rate Period
Series A	July 15, 2044	$	60,000,000	$	62,326,467	6.75%	⁽¹⁾	6.75%	28 days⁽¹⁾
Series E	April 10, 2015		110,000,000		108,843,840	6.11%		6.11%	Fixed
		$	170,000,000	$	171,170,307

(1) Special rate period effective September 5, 2007 through September 4, 2012.

The rates shown in the table above for Series A do not include commissions paid to the auction agent which are included in agent fees in the accompanying Statement of Operations. At the time the special rate period commenced, the Company paid commissions for Series A Notes in the amount of $240,000, which are being amortized over the special rate period. For each subsequent rate period, the interest rate will be determined by an auction conducted in accordance with the procedures described in the Series A Notes’ prospectus. The Notes are not listed on any exchange or automated quotation system.

10. Preferred Stock

The Company has 15,000 authorized shares of preferred stock, of which 2,800 shares are currently outstanding. The preferred stock has rights determined by the Board of Directors. The holders of preferred stock have voting rights equal to the holders of common stock (one vote per preferred share) and will vote together with the holders of shares of common stock as a single class except on matters affecting only the holders of preferred stock or the holders of common stock.

The preferred stock has a liquidation value of $25,000 per share plus any accumulated but unpaid distributions, whether or not declared. Holders of the preferred stock are entitled to receive cash distribution payments at an annual rate that may vary for each rate period as determined by the auction. In the event that there are not enough bidders in the auction at rates below the maximum rate as prescribed by the terms of the preferred stock, the auction fails. When an auction fails, the rate paid to continuing or new bidders is set at the maximum rate. A failed auction does not cause a mandatory redemption or affect the security’s liquidation preference. In the event of a failed auction, distributions continue to be paid at the maximum rates and times determined in the articles supplementary. The maximum rate on preferred stock based on current ratings is 200 percent of the greater of: (i) the applicable AA Composite Commercial Paper Rate or the applicable Treasury Index Rate or (ii) the applicable LIBOR as of the date of the auction.

The preferred stock is redeemable in certain circumstances at the option of the Company. Under the Investment Company Act of 1940, the Company may not declare dividends or make other distributions on shares of common stock or purchases of such shares if, at the time of the declaration, distribution or purchase, asset coverage with

NOTES TO FINANCIAL STATEMENTS (Unaudited)
(Continued)

respect to the outstanding preferred stock would be less than 200 percent. The preferred stock is also subject to a mandatory redemption if the Company fails to meet asset coverage ratios required under the 1940 Act or the rating agency guidelines if such failure is not waived or cured. At May 31, 2009, the Company was in compliance with asset coverage covenants and basic maintenance covenants for its preferred stock.

Estimated fair value of Auction Preferred I and Auction Preferred II Stock was calculated using the spread between the AA corporate finance debt rate and the U.S. Treasury rate with an equivalent maturity date plus the average spread between the current rates and the AA corporate finance debt rate. At May 31, 2009, the total spread was applied to the equivalent U.S. Treasury rate for each series and future cash flows were discounted to determine estimated fair value. The table below shows the number of shares outstanding, aggregate liquidation preference, estimated fair value, current rate as of May 31, 2009, the weighted-average rate for the period ended May 31, 2009 and the typical rate period for each series of preferred stock outstanding at May 31, 2009. The Company may designate a rate period that is different than the rate period indicated in the table below.

			Aggregate					Weighted-
	Shares		Liquidation		Estimated		Current	Average
Series	Outstanding		Preference		Fair Value		Rate	Rate	Rate Period

(2)		Special rate period effective September 9, 2007 through September 8, 2010.

The rates shown in the table above do not include commissions paid to the auction agent, which are included in agent fees in the accompanying Statement of Operations. At the time the special rate periods commenced, the Company paid commissions for Auction Preferred I Stock and Auction Preferred II Stock in the amount of $175,000 and $178,500, respectively, which are being amortized over the rate periods.

11. Common Stock

The Company has 100,000,000 shares of capital stock authorized and 23,442,791 shares outstanding at May 31, 2009 and November 30, 2008.

12. Credit Facility

On March 20, 2008, the Company entered into an agreement establishing an unsecured credit facility maturing on March 20, 2009. The credit agreement provided for a revolving credit facility of up to $92,500,000 that could be increased to $160,000,000 if certain conditions were met. Under the terms of the credit facility, U.S. Bank, N.A. served as a lender and the lending syndicate agent on behalf of other lenders participating in the credit facility. Outstanding balances generally accrued interest at a variable annual rate equal to one-month LIBOR plus 0.75 percent and unused portions of the credit facility accrued a non-usage fee equal to an annual rate of 0.15 percent.

On March 20, 2009, the Company entered into an extension of its credit facility through June 20, 2009. The terms of the extension provide for an unsecured revolving credit facility of up to $40,000,000. During the extension, outstanding balances accrue interest at a variable rate equal to one-month LIBOR plus 2.00 percent and unused portions of the credit facility accrue a non-usage fee equal to an annual rate of 0.25 percent.

Under the terms of the credit facility, the Company must maintain asset coverage required under the 1940 Act. If the Company fails to maintain the required coverage, it may be required to repay a portion of an outstanding balance until the coverage requirement has been met.

The average principal balance and interest rate for the period during which the credit facility was utilized during the period ended May 31, 2009 was approximately $19,600,000 and 1.78 percent, respectively. At May 31, 2009, the principal balance outstanding was $7,500,000 at an interest rate of 2.32 percent.

13. Subsequent Events

On June 1, 2009, the Company paid a distribution in the amount of $0.54 per common share, for a total of $12,659,107. Of this total, the dividend reinvestment amounted to $1,644,313.

On June 19, 2009, the Company entered into an amendment to its credit facility that extends the credit facility through June 20, 2010. The terms of the amendment provide for an unsecured revolving credit facility of $70,000,000. During the extension, outstanding balances will accrue interest at a variable rate equal to one-month LIBOR plus 2.00 percent and unused portions of the credit facility will accrue a non-usage fee equal to an annual rate of 0.25 percent.
