GWF Energy LLC is seeking approval of a "Four-Month" Application for Certification from the California Energy Commission for the construction and operation of the Henrietta Peaker Project. The project is to the south of and contiguous with Pacific Gas and Electric Company's Henrietta Substation, which is approximately 20 miles southwest of Hanford, in unincorporated Kings County, California.

The project is a nominal 91.4-megawatt, simple-cycle power plant, on a seven-acre fenced site within a 20-acre parcel The project will consist of the power plant, an onsite 70-kilovolt (kV) switchyard, and approximately 550 feet of new 70-kV transmission line. Natural gas for the facility will be delivered via approximately 2.2 miles of new 12-inch pipeline that will connect to the existing Southern California Gas Company (SoCalGas) Line 800 transmission pipeline, approximately one mile south of the intersection of 25th Avenue and the Avenal Cutoff.

The project will use two General Electric LM6000 PC Sprint combustion turbine generators (CTGs), each with a base load nominal output of 46.9 MW at annual average conditions.

GWF Energy LLC will construct, own, and operate the Henrietta Power Project. GWF Energy LLC is 50 percent owned by PSEG California Corporation and 50 percent owned by Harbinger GWF LLC. PSEG California Corporation is owned by PSEG Global USA Inc. Harbinger GWF LLC is owned by Harbert Cogen, Inc.

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.
