The Pastoria Energy Facility (PEF) is located in southeastern Kern County near the unincorporated communities of Grapevine and Lebec about 30 miles south of Bakersfield.
PEF is a nominal 750 MW combined-cycle, natural gas-fired facility consisting of three GE Energy 7FA gas turbines. Associated facilities include a 1.38-mile, 230 kilovolt (kV) electric overhead transmission line that interconnects to Southern California Edison’s Pastoria Substation; an 11.65-mile natural gas fuel supply line that connects with the Kern-Mojave Pipeline; and a 0.15-mile water supply pipeline that connects to the Wheeler-Ridge-Maricopa Water Storage District’s pipeline network. Access to the facility is via a 0.85-mile road that connects with Edmonston Pump Plant Road.
In June 13, 2001, the California Energy Commission (CEC) approved an ownership change (TN 20962) from Enron North America Corporation to Calpine Corporation.
On July 25, 2001, the CEC approved a Post-Certification Amendment (PCA) (TN 21721) to convert from aqueous to anhydrous ammonia to control facility emissions.
The Pastoria Energy Facility Expansion Project, a simple cycle addition (05-AFC-01C) was approved on November 8, 2006. However, the project was never built, and the license expired on December 18, 2011.
On February 24, 2012, the CEC approved a PCA (TN 63773) to modify the project by replacing certain components in the Advanced Gas Path on two of the three existing combustion turbines with parts that are designed to operate at new, higher firing temperatures. These replaced components will improve the turbine heat rate and generate power more efficiently.
On December 30, 2013, the CEC approved a PCA (TN 201427) to install a second brine crystallizer to PEF’s Zero Liquid Discharge system. The addition of a second crystallizer allows the plant to process water more efficiently.
Power Plant Certification and Exemption Processes
As required by the Warren-Alquist Act, the Energy Commission monitors Commission-certified energy projects throughout construction, operation, and closure to ensure compliance with the conditions of certification imposed by the Commission’s Final Decision for approving the projects.
