NRG, Dynegy Acquire Two Plants from Nevada Power
LCG, Nov. 20, 2000--NRG Energy Inc. and Dynegy Inc. announced jointly this morning that they will purchase two Las Vegas-area power plants with a combined capacity of 1,330 megawatts from the Nevada Power Co. subsidiary of Sierra Pacific Resources.The 740 megawatt Clark Generating Station located in southeastern Las Vegas consists of 10 natural gas-fired units that can burn fuel oil as a backup.The 605 megawatt Reid Gardner Generating Station, located 52 miles northeast of Las Vegas, consists of four baseload coal-fired units. Three 110 megawatt units are wholly owned by Nevada Power while a fourth 275 megawatt unit is jointly owned by Nevada Power and the California Department of Water Resources.NRG and Dynegy will acquire Nevada Power's 85 percent interest in the fourth Reid Gardner unit and the California water agency will retain its 15 percent interest.The sale of generation assets is a regulatory condition of the 1999 merger between Sierra Pacific Power Co. and Nevada Power Co. that formed Sierra Pacific Resources. Last month, NRG was named the successful bidder for Sierra Pacific's 50 percent interest in the 522 megawatt coal-fired North Valmy Generating Station and 100 percent interest in 25 megawatts of peaking units in northern Nevada.The acquisition of Clark and Reid Gardner includes a transitional power purchase agreement for Nevada Power to purchase energy and ancillary services until March 1, 2003 under a contract the companies say will help provide price stability for its customers throughout the transition to an open market in Nevada.The transaction is subject to approvals from the Federal Trade Commission, the Federal EnergyRegulatory Commission and the Nevada Public Utilities Commission. It is expected to close duringthe second quarter of 2001, the companies said.
