Calpine Drops Plans for Frisco-area Temporary Plants

LCG, Nov. 8, 2000--Calpine Corp. has dropped plans to build three temporary power plants of about 90 megawatts each near the San Francisco Bay north of its San Jose headquarters, according to an official of the California Energy Commission.

Claudia Chandler, an assistant executive director with the Energy Commission, said the state agency had received a letter from Calpine withdrawing its applications for authority to build the plants in San Mateo and Brisbane on the San Francisco Peninsula and Newark in the lower East Bay.

Chandler was unable to explain the reason for Calpine's decision and all the company would say was the withdrawal was caused by a "high degree of regulatory uncertainty." The Energy Commission is the siting authority for power plants built in the state and heretofore has given great weight to opposition by environmentalists and local "not in my back yard" interests.

Chandler said Calpine's permit application for a fourth temporary plant to be built in Santa Clara is still pending approval, as is an application by El Paso Merchant Energy Co. to build a 51 megawatt plant at the San Francisco International Airport.

The discontinued plants as well as the El Paso plant at the airport would pump their output into the Pacific Gas & Electric Co. system. The Santa Clara plant would be hooked up to the city's municipal utility.
