MINNEAPOLIS, June 25, 2001 (BUSINESS WIRE)—NRG Energy, Inc. (NYSE: NRG) acquired 1,081 megawatts (MW) of baseload electric generating plants from Delmarva Power and Light, a subsidiary of Wilmington, Del.-based Conectiv (NYSE: CIV). As part of the agreement, NRG entered into both short- and long-term purchase power contracts with Delmarva Power to provide energy and capacity for the Delmarva Peninsula.

"We are pleased to have a strong presence in the PJM market--a vibrant, relatively mature and well-functioning market for electricity," said David H. Peterson, chairman, president and CEO of NRG Energy. "This acquisition gives us a strong base from which to expand into a top three generator in this market."

The generating facilities acquired last Friday include those owned by Delmarva Power. The assets include the Indian River and Vienna Generating Stations and a partial interest in the Keystone and Conemaugh stations. A parcel of land in Dorchester County, Md. was also included in the purchase.

''Since we signed the purchase agreement in January 2000, it has been a long and difficult period of uncertainty for the employees who run these plants and we are glad to welcome them to NRG Energy,'' said Craig A. Mataczynski, president and chief executive officer of NRG North America. ''We look forward to welcoming the employees from the New Jersey-based plants in the near future.''

NRG has extended its signed purchase agreement for an additional 794 MW of assets it intends to acquire from Conectiv subsidiary, Atlantic City Electric Company. These assets include the BL England and Deepwater Generating Stations as well as additional partial ownership interests in Conemaugh and Keystone Stations. NRG expects to receive New Jersey Board of Public Utilities (NJBPU) approval in the third quarter 2001 for the purchase of these assets. Previously disclosed earnings guidance of $1.35 per share remains unchanged.
