NRG Energy to Combine with Texas Genco Creating the Leading Competitive Power Generation Company in the United States

Transaction Valued at $5.8 Billion

PRINCETON, NJ and HOUSTON, TX, October 2, 2005 — NRG Energy, Inc. (NYSE: NRG) and Texas Genco LLC have entered into a definitive agreement for NRG to acquire all the outstanding equity of Texas Genco LLC for approximately $5.8 billion, comprised of approximately $4 billion in cash and $1.8 billion in common and preferred stock. In addition, NRG will assume approximately $2.5 billion of Texas Genco debt.

The combination of NRG and Texas Genco will create the premier wholesale power generation company in the United States. With Texas Genco, NRG will have the broadest geographic reach and an unmatched portfolio of quality power generation assets of any independent power producer, with a significant presence in the key competitive wholesale power markets in the United States. The combined company will also be a leading fuel diversified energy provider. Further, this combination is expected to drive substantially greater earnings and cash flow per share for NRG that will enhance the Company’s financial strength and flexibility and enable it to pursue additional growth opportunities.

“Texas Genco is an ideal strategic fit with NRG,” said ▇▇▇▇▇ ▇▇▇▇▇, NRG’s President and Chief Executive Officer. “The strengths of its people and its assets align closely with our own, bolstering NRG’s platform for growth and our ability to drive value for our shareholders.”

“This is an exciting combination for our employees, shareholders and the communities in which we operate,” said Texas Genco Chairman and Chief Executive Officer ▇▇▇▇ ▇▇▇▇▇. “Like NRG, we at Texas Genco have an unwavering focus on safety, teamwork, operational excellence, and value creation. I am confident that the combined company will set new standards and achieve new heights.”

Financial and Strategic Benefits:

Purchase Price Drivers: The purchase price paid for Texas Genco was based on their near term substantially hedged portfolio and a conservative view on longer term gas prices. The $8.3 billion enterprise value divided by Texas Genco’s expected earnings in 2006 results in a purchase price multiple below NRG’s current trading multiple. Furthermore, the $8.3 billion purchase price includes the present value of approximately $500 million in after tax cash benefits that are expected to result from the increased tax basis of the Texas Genco assets that occur at transaction closing.

Immediate Accretion to Earnings and Cash Flow: Post closing, NRG expects the transaction to be immediately and significantly accretive to both earnings per share and cash flow per share.

Stability and Growth of Earnings and Cash Flow: Texas Genco has sold forward, on average, 82%,of its available baseload capacity over the next four years, providing a stable source of earnings and cash flow to the combined entity.

Strong, Flexible Capital Structure: The transaction is expected to be financed through a combination of debt and equity that will enable the company to achieve a net debt to total capital ratio within NRG’s target range of 45-55% by year end 2006. Additionally, Texas Genco’s collateral program will meaningfully enhance the Company’s liquidity position and hedging capacity. NRG intends to refinance the first lien debt of both companies. Upon completion of the transaction, the Company expects to have approximately 141.1 million common shares outstanding, of which approximately 35.4 million shares will be divided among and held independently by each of the current owners of Texas Genco.

The equity component of the consideration is valued at approximately $1.8 billion, and consists of approximately 35.4 million shares of common stock, plus approximately nine million additional shares of common stock, which can be delivered at NRG’s option in either common stock or the equivalent in cash or preferred stock.

▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Senior Funding, Inc. and Citigroup Global Markets, Inc. have provided committed financing to NRG in support of financing the cash portion of the transaction.

Enhanced Platform for Growth in Key Market Regions: Texas Genco is the second-largest generation company within ERCOT, one of the nation’s largest and fastest growing power markets. Texas Genco’s plants, including its 44% interest in the South Texas Project nuclear generating facility, provide approximately 14% of the aggregate net generation capacity in the ERCOT market, a state that has been a pioneer in the establishment of a competitive wholesale electric power market.

With Texas Genco, NRG will have a U.S. generation portfolio of approximately 23,920 MW of capacity that is fuel, dispatch and geographically diverse. The Company will have a strong asset position in all of the key competitive wholesale markets in the United States, including the Northeast, South Central, California and Texas.

Industry Restructuring: This transaction represents the first important step in the necessary and long-awaited restructuring of the wholesale power generation industry.

“This transaction represents a major milestone for our Company and our industry. With Texas Genco, we will further increase our financial strength and flexibility and enhance our geographic breadth, technical expertise and diversity of fuel sources,” ▇▇▇▇▇ continued. “We believe these advantages will enable NRG to make even more of a difference as our country faces up to the challenging energy environment that currently exists. With Texas Genco, NRG can better provide low cost, stable and reliable energy solutions to the regions we serve.”

High Quality Asset Base that Is Well-Positioned Environmentally: Approximately 48% of Texas Genco’s approximately 11,000 MW net generating portfolio consists of three low-cost,

efficient solid-fuel baseload plants. Given that generation units are generally dispatched in order of lowest cost and that approximately 73% of the net generation capacity in the ERCOT market is from higher-cost natural gas-fired units, Texas Genco’s baseload units operate nearly 100% of the time they are available. In additional to having excess SO₂ allowances, since 1999, Texas Genco has invested over $700 million for NO_x emissions controls at its plants, resulting in a fleet that operates at one of the lowest NO_x emission rates in the country. The following table provides specifics on Texas Genco’s generating sites:
