REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Trustees and Participants in the

Reliant Energy, Inc. Union Savings Plan:

We have audited the accompanying statements of net assets available for benefits of the Reliant Energy, Inc. Union Savings Plan (the “Plan”) as of December 31, 2007 and 2006, and the statement of changes in net assets available for benefits for the year ended December 31, 2007. 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 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 audit 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, as well as 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 as of December 31, 2007 and 2006, and the changes in net assets available for benefits for the year ended December 31, 2007 in conformity with accounting principles generally accepted in the United States of America.

Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The accompanying supplemental schedule, listed in the Table of Contents, is presented for the purpose of additional analysis and is not a required part of the basic 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. The 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 basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

RELIANT ENERGY, INC. UNION SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS

1.		DESCRIPTION OF THE PLAN
		General - The Reliant Energy, Inc. Union Savings Plan (the “Plan”) is a defined contribution plan sponsored by Reliant Energy, Inc. covering substantially all of the eligible bargaining unit employees of Reliant Energy, Inc. or a subsidiary or an affiliate of Reliant Energy, Inc. (collectively, the “Company”) that has adopted the Plan, and whose employment is covered by a collective bargaining agreement that provides for participation in the Plan. The following description of the Plan is provided for general information purposes only. Participants should refer to the Plan document for a more complete description of the Plan provisions. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”).
		Effective January 22, 2007, the Plan was amended to change the definition of eligible compensation pertaining to employee contributions, change contribution percentages, change provisions for employer matching contributions and add the ability to make Roth contributions for certain bargaining unit employees in accordance with the terms of their new collective bargaining agreement.
		Eligibility - Under the provisions of the Plan, represented employees are eligible to participate in the Plan if provided in the terms of their respective collective bargaining agreements. Represented employees who participate or who are eligible to participate in the Plan immediately preceding January 1, 2006, continue to participate or be eligible to participate in the Plan on or after January 1, 2006. From and after January 1, 2006, except as specified in the participants’ respective collective bargaining agreement, each eligible employee who is not a participant and who began service with the Company on or after January 1, 2006, was initially eligible to participate in the Plan as soon as practicable following the later of January 1, 2006 or the date the employee first began service with the Company. Any participant who terminates service and subsequently recommences service with the Company will again become eligible to participate in the Plan as soon as practicable following the first date the employee recommences service; provided, however, that each such participant who was a grandfathered employee of a specific bargaining unit, as defined in the plan document, prior to such termination of service, will not be a grandfathered employee on or after such re-employment date.
		Contributions - Participants may elect to contribute a percentage of their compensation on a pre-tax and/or after-tax basis as permitted under the terms of their respective collective bargaining agreements, and/or up to the Internal Revenue Code (the “Code”) section 401(a) (17) limit. The annual eligible compensation limit was $225,000 and $220,000 for 2007 and 2006, respectively. Active participants who are, or will be, age 50 or older during a calendar year are eligible to make additional pre-tax contributions (“Catch-Up Contributions”) to the Plan for that year in excess of the annual pre-tax contribution limit up to a maximum amount permitted by the Code. The total amount of participant pre-tax contributions was limited to $15,500 and $15,000 in 2007 and 2006, respectively. The maximum Catch-Up Contribution amount was $5,000 for 2007 and 2006. The Company makes matching contributions in accordance with the terms of the participants’ respective collective bargaining agreement. Some collective bargaining agreements provide for a discretionary Company contribution each pay period and an annual discretionary Company contribution. At December 31, 2007 and 2006, the Plan had an annual discretionary Company contributions receivable of $597,947 and $523,478, respectively. Plan participants who are eligible for these annual discretionary Company contributions do not have to contribute to the Plan to receive the Company contribution.

		The Plan adopted a qualified Roth contribution program for certain represented employees. Under this program, participants may elect to treat all or a portion of compensation that would otherwise be eligible to defer as pre-tax contributions as designated Roth contributions, as defined in section 402A(c)(1) of the Code.
		Participant Accounts - Individual accounts are maintained for each Plan participant. Each participant’s account is credited with the participant’s contributions, the Company’s matching contributions, allocations of Company discretionary contributions, if applicable, any rollover contributions made by the participant and Plan earnings, and may be charged with an allocation of administrative expenses. Participant accounts are funded as soon as administratively possible. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.
		Investments - Participants direct the investment of their contributions, Company matching contributions (if any) and Company payroll discretionary contributions (if any) into various investment options offered by the Plan. The Company’s annual discretionary contribution, if applicable, may be made in cash or Company stock. If the contribution is made in Company stock, participants can transfer this contribution to any available investment option.
		Vesting - Participants are fully vested in their contributions as of their participation date. Participants vest in Company contributions according to their respective collective bargaining agreements.
		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. During the period from July 1, 2006 to December 31, 2006, as a result of Hurricanes Katrina, Rita, and Wilma, and in response to new federal laws and IRS guidance, the Plan was amended to provide loans of up to $100,000 or 100% of the participant’s vested account balance for certain eligible participants entitled to disaster relief. Eligible participants may also request a one-year delay of the scheduled repayment date. The loans are secured by the balance in the participant’s account and bear interest at rates commensurate with local prevailing rates as determined under the Plan. Principal and interest are paid ratably through payroll deductions.
		Payment of Benefits - On termination of service, a participant or beneficiary may elect to receive either a lump-sum amount equal to the value of the participant’s vested interest in his or her account, or monthly, quarterly, semi-annual or annual installments not to exceed ten years.
		Forfeited Accounts - At December 31, 2007 and 2006, forfeited nonvested accounts totaled $59,968 and $42,940, respectively. These accounts will be used to reduce future Company contributions. During 2007, Company contributions were reduced by $67 from forfeited nonvested accounts.

2.		SIGNIFICANT ACCOUNTING POLICIES
		Basis of Financial Presentation - The accompanying financial statements of the Plan are prepared under the accrual basis of accounting in conformity with accounting principles generally accepted in the United States of America.
		Fully Benefit-Responsive Investment Contracts - The Plan accounts for fully benefit-responsive contracts according to Financial Accounting Standards Board Staff Position, FSP AAG INV-1 and SOP 94-4-1, Reporting of Fully Benefit-Responsive Investment Contracts Held by Certain Investment Companies Subject to the AICPA Investment Company Guide and Defined-Contribution Health and Welfare Pension Plans (the “FSP”). As described in the FSP, investment contracts held by a defined contribution plan are required to be reported at fair value. However, contract value is the relevant measurement attribute for that portion of the net assets available for benefits of a defined contribution plan attributable to

		fully benefit-responsive investment contracts because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan. The Plan invests in investment contracts through participation in the Vanguard Retirement Savings Trust (the “RST”), a common/collective trust fund. As required by the FSP, the Statement of Net Assets Available for Benefits presents the fair value of the RST as well as the adjustment of the portion of the RST related to fully benefit-responsive contracts from fair value to contract value. The Statement of Changes in Net Assets Available for Benefits is prepared on a contract value basis. The effect on the 2007 and 2006 financial statements was an increase and decrease to the fair value of investments of $148,723 and $157,183, respectively.
		Use of Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and changes therein, as of the date of the financial statements. Actual results could differ from those estimates.
		Market Risk - The Plan provides for investments in various investment securities, including CenterPoint Energy, Inc. common stock (closed to new investment) and the Company’s common stock, that are exposed to certain risks such as interest rate, credit, and overall market volatility. Due to the level of risk, changes in the value of investment securities could occur in the near term, and these changes could materially affect the amounts reported in the Statements of Net Assets Available for Benefits.
		Administrative Expenses - Administrative expenses of the Plan are paid by either the Plan or the Plan’s sponsor as provided in the Plan document.
		Payment of Benefits - Benefits are recorded when paid.
		Investment Valuation and Income Recognition - The Plan’s investments are stated at fair value. Shares of registered investment companies (mutual funds) are valued at quoted market prices which represent the net asset value of shares held by the Plan at the end of the year. Units of the RST are valued at net asset value at the end of the year, which approximates fair value. The common stock funds are valued at the year-end unit closing price (comprised of the year-end market price plus uninvested cash position). Participant loans are valued at cost which approximates fair value.
		Purchases and sales of investments are recorded on a trade-date basis. Interest income is accrued when earned. Dividend income is recorded on the ex-dividend date. Capital gain distributions are included in dividend income.
		Recent Accounting Pronouncement - In September 2006, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 157 (“SFAS 157”), Fair Value Measurements. SFAS 157 defines fair value, outlines a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007. The Plan is currently evaluating the impact of adopting SFAS 157.
3.		ASSETS TRANSFERRED FROM THE PLAN
		During 2007, assets of approximately $1.2 million transferred out of the Plan as a result of net plan-to-plan transfers of participant account balances to the Reliant Energy, Inc. Savings Plan.

4.		INVESTMENTS
		Plan assets are held at Vanguard Fiduciary Trust Company (the “Trustee”). The following presents investments that represent 5% or more of the Plan’s net assets:

		December 31,
		2007				2006
Mutual Funds:
American Funds EuroPacific Growth Fund		$	6,367,200			$
Fidelity Securities Fund: Fidelity Dividend Growth Fund							5,591,923
Neuberger Berman Genesis Trust			10,396,501				8,976,202
Vanguard 500 Index Fund Investor Shares			11,784,798				11,493,437
Common/Collective Trust Funds:
Vanguard Retirement Savings Trust *			19,506,791				16,491,898
Common Stock Funds:
Reliant Energy Common Stock Fund			9,010,865				6,534,468

During 2007, the Plan’s investments, including gains and losses on investments bought and sold, as well as held during the year, appreciated in value as follows:

Mutual funds		$	2,103,907
Common stocks			4,993,670
		$	7,097,577

5.		PLAN TERMINATION
		Although it has not expressed any intention to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of a plan termination, participants would become 100% vested in their accounts.
6.		RELATED PARTY TRANSACTIONS
		The Plan invests in shares of mutual funds and a common/collective trust fund managed by an affiliate of the Trustee, as well as in shares of common stock of the Company. The Plan also provides for loans to participants. Transactions in such investments qualify as party-in-interest transactions which are exempt from the prohibited transaction rules.

7.		TAX STATUS
		The Plan obtained its latest determination letter dated July 23, 2007, in which the Internal Revenue Service stated that the Plan was in compliance with the applicable requirements of the Code. The plan administrator believes that the Plan is currently designed and being operated in compliance with the applicable requirements of the Code. Therefore, no provision for income taxes has been included in the Plan’s financial statements.
8.		SUBSEQUENT EVENTS
		The Plan was amended, effective January 1, 2008, to determine eligible compensation for the purpose of annual discretionary contributions, to include compensation earned while participating in another qualified plan sponsored by the Company. The payroll discretionary company contribution of 2% will be limited to the Social Security wage base for each calendar year. The amendment also allows unclaimed benefits to be used to reinstate any previously forfeited benefits or to reduce Company contributions.
