             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Plan Administrator
Employees' Savings Plan and Employee
 Stock Ownership Plan of Consumers Energy Company

We have audited the accompanying statements of net assets available for benefits
of Employees' Savings Plan and Employee Stock Ownership Plan of Consumers Energy
Company as of December 31, 2004 and 2003, and the related statement of changes
in net assets available for benefits for the year ended December 31, 2004. These
financial statements are the responsibility of the Plan's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. We were not engaged to perform an
audit of the Plan's internal control over financial reporting. Our audits
included consideration of internal control over financial reporting as a basis
for designing audit procedures that are appropriate in the circumstances, but
not for the purpose of expressing an opinion on the effectiveness of the Plan's
internal control over financial reporting. Accordingly, we express no such
opinion. An audit also includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan at
December 31, 2004 and 2003, and the changes in its net assets available for
benefits for the year ended December 31, 2004, in conformity with U.S. generally
accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying supplemental schedule of assets
(held at end of year) as of December 31, 2004, is presented for purposes of
additional analysis and is not a required part of the financial statements but
is supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. This supplemental schedule is the responsibility of the
Plan's management. The supplemental schedule has been subjected to the auditing
procedures applied in our audits of the financial statements and, in our
opinion, are fairly stated in all material respects in relation to the financial
statements taken as a whole.

1. DESCRIPTION OF PLAN

The following description of the Employees' Savings Plan and Employee Stock
Ownership Plan of Consumers Energy Company (the Plan) provides only general
information. Participants should refer to the Plan document for a complete
description of the Plan's provisions.

GENERAL

The Plan is a defined contribution plan designed to encourage and assist
employees of CMS Energy Corporation and its subsidiaries, which are at least 80%
owned and have adopted the Plan (the Company or Employer) in saving for the
future. The Plan is a voluntary program that allows eligible participants to
invest their contributions in various investment funds. All regular employees of
the Company as defined by the Plan, may participate in the Plan. The Plan is
subject to the provisions of the Employee Retirement Income Security Act of 1974
(ERISA).

CONTRIBUTIONS

Participants in the Plan may elect to make pre-tax or after-tax contributions 
up to 25% of their eligible compensation, as defined by the Plan. If a
participant's annual salary is equal to or more than $90,000, the most that can
be contributed by the Employer on behalf of the participant to the Plan is
12.5%. All percentage contributions are subject to certain dollar limitations as
set forth in the Internal Revenue Code (the Code).

The Company will make matching employer contributions in an amount equal to $.50
for each $1.00 contributed by a participant, up to a maximum of 6% of the
participant's eligible compensation.

Effective September 1, 2002, the matching employer contributions to the Plan
were suspended. The matching employer contributions resumed on the first pay
attributable to work on or after January 1, 2005.

Effective September 1, 2002 all participant balances became eligible for
reallocation at the discretion of the participant.

Effective September 1, 2002, incentive contributions to the Plan were
eliminated.

Effective September 1, 2004, the savings portion of the Plan was amended to
provide that authorized but unissued shares of common stock of CMS Energy
Corporation or other securities convertible to such common stock may be used to
satisfy allocations elected by participants.

1. DESCRIPTION OF PLAN (CONTINUED)

PARTICIPANT ACCOUNTS

Each participant's account is credited with the participant's contributions,
matching employer contributions and allocations of Plan earnings. The benefit to
which a participant is entitled is the benefit that can be provided from the
vested value of the participant's account.

VESTING

Participants are immediately vested in their contributions plus actual earnings
thereon. Vesting in the matching employer contributions and the incentive
contributions of their accounts are based on years of service. A participant
becomes 10% vested for each of the first two years of service with the Company,
and 20% for each of the next four years of service.

PARTICIPANT LOANS

Participants may borrow from their fund accounts up to a maximum of $50,000 or
50% of their vested account balance, whichever is less. Loan terms range up to
five years for a general purpose loan or up to 15 years for the purchase of a
primary residence. The loans are secured by the balance of the participant's
account and bear interest at a rate commensurate with local prevailing rates as
determined quarterly by the Plan administrator. Principal and interest are paid
ratably through payroll deductions.

PAYMENT OF BENEFITS

Upon termination of service, death, disability or retirement, a participant may
receive a lump-sum amount equal to the vested value of his or her account.

FORFEITURES AND ADMINISTRATIVE EXPENSES

Forfeitures result from matching employer contributions and incentive
contributions remaining in the Plan for terminated participants' nonvested
account balances. Forfeitures generated are added to a forfeiture reserve
account and are available to offset matching employer contributions. Such
amounts forfeited in 2004 and 2003 were $55,386 and $59,392, respectively, and
are treated as a reduction of the Employer's contribution. As of December 31,
2004, the cumulative unallocated forfeitures were $158,358; as of December 31,
2003 they were $103,042. Expenses related to the administration and investment
management of the Plan are charged against the assets of the investment funds
offered to plan participants. Brokerage fees, commissions, stock transfer taxes
and other expenses in connection with the purchases, sales and distributions of

1. DESCRIPTION OF PLAN (CONTINUED)

FORFEITURES AND ADMINISTRATIVE EXPENSES (CONTINUED)

securities for each investment fund are charged to the fund that incurred the
cost. Fees for obtaining loans are charged to the participant that requested the
loan.

PLAN TERMINATION

Although it has not expressed the intention to do so, the Company has reserved
the right to terminate the Plan at any time by resolution of its Board of
Directors. The value of the participant accounts will be determined as of the
effective date of the termination and be distributed as provided by the Plan.

2. SIGNIFICANT ACCOUNTING POLICIES

INVESTMENT VALUATION AND INCOME RECOGNITION

Except for the investment contracts, the Plan's investments are stated at fair
value which equals the quoted market price on the last business day of the plan
year. The shares of registered investment companies are valued at quoted market
prices which represent the net asset values of shares held by the Plan at
year-end. The fair value of the participation units owned by the Plan in the
common trust fund accounts are based on quoted redemption values on the last
business day of the plan year. The participant loans are valued at their
outstanding balances, which approximate fair value.

Investment contracts are recorded at their contract values, which represent
contributions and reinvested income, less any withdrawals plus accrued interest,
because these investments have fully benefit-responsive features. For example,
participants may ordinarily direct the withdrawal or transfer of all or a
portion of their investment at contract value. However, withdrawals influenced
by Company-initiated events, such as in connection with the sale of a business,
may result in a distribution at other than contract value. There are no reserves
against contract values for credit risk of contract issues or otherwise.
Contract value approximates fair value. The average yield for these contracts
was 6.11% in 2004 and 6.20% in 2003. The crediting interest rate for these
investment contracts ranged from approximately 5.40% to 6.99% in 2004 and 5.40%
to 7.10% in 2003. Rates on contracts remain fixed for the life of each contract.

Upon completion of the recordkeeping transfer to Fidelity Investments, as
described in Note 3, Investments, the valuation of participant accounts was
changed to daily pricing from monthly pricing.

                          Notes to Financial Statements

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

USE OF ESTIMATES

The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to make estimates that affect
the amounts reported in the financial statements and accompanying notes. Actual
results could differ from those estimates.

3. INVESTMENTS

As of January 3, 2003, Fidelity Investments became the trustee and recordkeeper
for the Plan. After December 31, 2002, Consumers Energy Company ceased
recordkeeping services for the Plan. As of the close of business on December 31,
2002, Comerica Bank of Detroit, Michigan ceased providing trustee services to
the Plan and the Plan assets were transferred to Fidelity Investments.

During 2004, the Plan's investments (including investments purchased and sold,
as well as held, during the year) appreciated (depreciated) in fair value as
determined by quoted market prices as follows:

4. CONTINGENCY

CMS Energy Corporation is a named defendant, along with Consumers Energy
Company, CMS Marketing, Services and Trading Company and certain named and
unnamed officers and directors, in two lawsuits brought as purported class
actions on behalf of participants and beneficiaries of the Plan. The two cases,
filed in July 2002 in the U.S. District Court for the Eastern District of
Michigan, were consolidated by the trial judge and an amended consolidated
complaint was filed. Plaintiffs allege breaches of fiduciary duties under ERISA
and seek restitution on behalf of the Plan with respect to a decline in value of
the shares of the CMS Energy Corporation Common Stock held in the Plan.
Plaintiffs also seek other equitable relief and legal fees. In March 2004, the
judge granted in part, but denied in part, CMS Energy Corporation's motion to
dismiss the complaint. The judge has conditionally granted plaintiffs' motion
for class certification. A trial date has not been set, but is expected to be no
earlier than

4. CONTINGENCY (CON'T)

mid-2006. CMS Energy Corporation and Consumers Energy Company will defend
themselves vigorously in this litigation but cannot predict its outcome.

5. INCOME TAX STATUS

The Plan has received a determination letter from the Internal Revenue Service
dated April 24, 2002, stating that the Plan is qualified under Section 401(a) of
the Code and, therefore, the related trust is exempt from taxation. Once
qualified, the Plan is required to operate in conformity with the Code to
maintain its qualification. The Plan administrator believes the Plan is being
operated in compliance with the applicable requirements of the Code and,
therefore, believes that the Plan is qualified and the related trust is tax
exempt.

6. RISKS AND UNCERTAINTIES

The Plan invests in various investment securities. Investment securities are
exposed to various risks such as interest rate, market and credit risks. Due to
the level of risk associated with certain investment securities, it is at least
reasonably possible that changes in the values of investment securities will
occur in the near term and that such changes could materially affect
participants' account balances and the amounts reported in statements of net
assets available for benefits.

7. SUBSEQUENT EVENTS

Effective March 28, 2005, the Company amended the savings portion of the Plan to
reduce the amount paid out in a lump sum without the consent of the participant
upon termination from $5,000 to $500 based on changes to the federal laws
relating to treatment of de minimis distributions from a qualified plan and for
administrative ease.

Effective September 30, 2005, the matching employer contribution for union
employees will increase from $.50 for each $1.00 contributed by a participant to
$.60 for each $1.00 contributed by a participant. The maximum portion of the
participant's eligible compensation eligible for the match remains at 6%.
