Calpine Completes Phase II of Pastoria Energy Center

LCG, July 7, 2005--Calpine Corporation announced yesterday that operations have commenced for Phase II of its Pastoria Energy Center, located south of Bakersfield, California. Phase I of the project, with a capacity of 250 MW, began delivering power to Southern California in early May. Phase II adds another 500 MW of gas-fired, electric generating capacity for serving electric loads in Southern California.

The Pastoria Energy Station is an efficient, combined-cycle facility that produces a relatively limited quantity of air emissions, including greenhouse gases.

At the end of May, Calpine's Metcalf Energy Center, located in San Jose, California, began operations. Similar to the Pastoria Energy Station, the Metcalf Energy Center is a 600 MW, combined-cycle power plant. The Pastoria and Metcalf plants provide a significant increase in power supplies to meet California's growing demand for electricity. Following the completion of the two projects, Calpine's California assets will total over 5,750 MW.
