Triumvirate to Build 633 Megawatt Houston Plant

LCG, Nov. 7, 2000--A partnership between a U.S. energy company and a German independent power producer announced yesterday that it had formed a joint venture with another U.S. firm to build, operate and manage a 633 megawatt natural gas-fired merchant power plant 30 miles southwest of Houston, Texas.

Avista Corp. and Steag AG of Germany were joined by NRG Energy Inc. in the Brazos Valley project. Avista-Steag will own 51 percent of the plant and NRG the remaining 49 percent. Financial data were not disclosed.

Eberhard Schmidt, speaking for Avista-Steag, said "The Brazos Valley project represents an important step toward increasing the efficiency of the Electric Reliability Council of Texas generation fleet, 63 percent of which is between 21 and 40 years of age."

Schmidt added "One estimate puts total ERCOT generation shortfall at over 10,000 megawatts in the year 2005 at a 15 percent reserve margin. This project will help reverse that trend."

Construction of the Brazos Valley plant is scheduled to begin early next year with commercial operation expected in January 2003.
