MINNEAPOLIS (July 25, 2001) - NRG Energy, Inc. (NYSE: NRG) today reported record net income and earnings per share for the six-month period ending June 30, 2001. Earnings per share increased 26 percent to $0.44 for the six months from $0.35 in 2000. Earnings per share for the second quarter of 2001 were $0.25 versus $0.28 in the second quarter of 2000. Net income increased 61 percent to $84.3 million year-to-date 2001 compared to $52.3 million during the previous comparable period. Total revenues grew to $1.37 billion for the six-month period from $845.0 million in 2000, an increase of 62 percent. "NRG's strong results overall for the first two quarters of 2001 keep us on track to meet our aggressive growth and financial objectives for this year and we remain comfortable with earnings guidance for the year of $1.35 per share," said David H. Peterson, chairman, president and chief executive officer. "NRG continues to deliver for our shareholders by expanding our highly diversified and well-positioned business platform in attractive markets in the United States and in select markets internationally." Peterson went on to say, "We are focused on creating value for NRG shareholders through our strong acquisition program, continuing success in augmenting returns through our outstanding power marketing area, a construction program that will bring more than 6,600 MW of efficient and environmentally responsible generating capacity online by the end of 2003, and NRG's world-class development efforts leveraged through strategic relationships." During the second quarter, NRG closed on the following projects that have achieved commercial operation:

PROJECT NAME NET MW INCREASE LOCATION Indian River, Vienna, etc. 1,081 Del., Penn., and Md., USA Audrain 640 Missouri, USA Csepel, Schkopau & MIBRAG 748 Germany and Hungary COBEE & Bulo Bulo 135 Bolivia Chowchilla II 49 California, USA
In addition to acquisitions and development, NRG's evolving power marketing operation is proving to be a competitive strength. NRG has one of the industry's most diversified generation portfolios. This diversity, in terms of geographic markets, fuels and dispatch profiles, allows NRG to follow the electric load in a given market. NRG's strategy is to maximize returns and minimize risks in uncertain markets through its diverse portfolio and not to depend on any single fuel, technology, or market to generate its return and growth requirements. The company also manages risk through the prudent use of long-term power sales and fuel-purchase contracts to lock in margins. "NRG benefits from the diversity of our portfolio in a number of ways," said Peterson. "NRG has enjoyed the earnings upside from significant coal-fired generating assets during periods of high natural gas prices. NRG also has about 20 percent of our assets located in select overseas markets. We are careful, experienced developers and operators of generation facilities and will continue to close well-structured transactions overseas as an important adjunct to our earnings diversity." Other events of note occurring in the second quarter of 2001 include an NRG debt offering of $690 million in senior notes, comprised of $350 million of 7.75 percent notes due 2011 and $340 million of 8.625 percent notes due 2031. In May, NRG also closed on a $2 billion construction/acquisition revolver that is an innovative piece of NRG's overall financing strategy. NRG is a leading global energy company engaged primarily in the acquisition, development, construction, ownership and operation of power generating facilities. The company's operations utilize such diverse fuel sources as natural gas, oil, coal and coal seam methane, biomass, landfill gas, refuse-derived fuel, and hydro.

3 including obtaining competitive contracts and construction delays; and factors affecting the availability or cost of capital, such as changes in interest rates and market perceptions of the power generation industry, NRG or any of its subsidiaries.
