Calpine to Supply 400 Megawatts to PG&E

LCG, Oct. 18, 200--Calpine Corp. and Pacific Gas & Electric Co. have signed a two-year agreement under which the independent power producer will furnish PG&E with 400 megawatts of firm capacity beginning next July 1.

Calpine said the power would be produced by its Northern California generating facilities, which could include its new 500 megawatt Sutter Energy Center and its Geysers geothermal complex purchased from PG&E.

The contract is possibly the first between an independent power producer and a regulated utility since state regulators dropped the misguided ban against bilateral power supply contracts between California's three investor-owned utilities and merchant power companies.

"Calpine's entering into this agreement with PG&E clearly demonstrates how new merchant plants and open competition can provide Californians relief from high energy prices," said Bill Ross, manager of market development. "Two of Calpine's new energy centers in northern California will be entering production just in time to help alleviate anticipated energy shortages next summer."

The value of the PG&E deal was not disclosed.
