Calpine Buys 500 Megawatt Project from PG&E

LCG, July 11, 2001--Calpine Corp. and PG&E National Energy Group said jointly yesterday that Calpine has completed the acquisition of the 500 megawatt Otay Mesa power project in San Diego County, Calif. for an undisclosed sum.

The Otay Mesa project has been in development by the PG&E unit for three years, and was finally approved by the California Energy Commission in April. Calpine will begin construction this summer, with commercial operation penciled in for mid-2003.

Under terms of the sale, Calpine will build, own and operate the facility and PG&E National Energy Group will contract for up to 250 megawatts of output under a 10-year tolling arrangement. Calpine will market the balance of the output through its energy services group.

"This project will directly address the electricity supply imbalance that currently exists in San Diego County," said Ron Walter, Calpine's senior vice president for business development. "Otay Mesa is an important component needed to ensure price stability and power reliability for San Diego and all of California."

The project is located within a 46-acre property on the eastern portion of Otay Mesa, near the base of the San Ysidro Mountains, approximately 1.5 miles from the United States-Mexico border.
