On April 29, 2005, Pastoria Energy LLC filed an Application for Certification (AFC) for the 160 megawatt (MW) expansion of the Pastoria Energy Facility. This expansion (PEFE) project, seeks approval from the Energy Commission to construct and operate an additional 160 MW unit at its existing power plant site. The previously approved 750 MW Pastoria Energy Facility (PEF) was analyzed and licensed December 20, 2000, as part of the Energy Commission's facility licensing proceeding, Docket # 99-AFC-7. The first unit of the original project is scheduled to go on line in May 2005.

The expansion project is proposed to be located on existing 30 acre site at the Tejon Ranch in Kern County. The site is about 30 miles south of Bakersfield and about 6.5 miles east of Interstate 5 near the base of the Tehachapi Mountains, in Township 10 North, Range 18 West, and is approximately 0.85 mile north of the California Aqueduct and about 1.3 miles north of the Edmonston Pumping Plant (California Department of Water Resources). The facility address is 39789 Edmonston Pumping Plant Road, Lebec, CA.

The proposed expansion incorporates one additional natural gas-fired, F-Class combustion turbine generator (CTG) operating in simple cycle mode into the original three-unit phase 1, for a total of four units. The plant will continue to use Best Available Control Technology (BACT) to minimize gas turbine emissions. The PEFE applicant plans to use Selective Catalytic Reduction for pollution control with aqueous ammonia as the reagent in the catalytic reduction process. The PEFE project will not require any changes to the existing facility's fuel or water supplies, nor will it require upgrading of the transmission system.

Energy Commission Facility Certification Process

The California Energy Commission is the lead agency (for licensing thermal power plants 50 megawatts and larger) under the California Environmental Quality Act (CEQA) and has a certified regulatory program under CEQA. Under its certified program, the Energy Commission is exempt from having to prepare an environmental impact report. Its certified program, however, does require environmental analysis of the project, including an analysis of alternatives and mitigation measures to minimize any significant adverse effect the project may have on the environment.
