This proposed 95-megawatt (MW) simple-cycle natural gas-fired power plant at the Hanford Energy Park (HEP) in Hanford, Kings County, California, is designated the Hanford Energy Park Peaker (HEPP). GWF Power Systems Company, Inc. (GWF) is applying to the California Energy Commission to construct and operate the HEPP plant at the HEP, immediately adjacent to the existing GWF Hanford cogeneration plant just north of Idaho Avenue, between the existing GWF facility to the west and the Burlington Northern & Santa Fe Railway tracks to the east.

The project owner is GWF Power Systems Company, Inc., 4300 Railroad Avenue, Pittsburg, California 94565, Tel. (925) 431-1444, Fax. (925) 431-0515.

GWF Power Systems Company, Inc. will construct, own, and operate the HEPP plant. GWF is wholly owned by National Energy Partners (NEP). NEP is a partnership owned equally by Harbert Cogen, Inc. and PSEG Global USA Inc. The HEPP plant will be a 95-MW net (May-October operations) natural gas-fired simple cycle power plant, with a 115-kilovolt (kV) switchyard and approximately 1.2 miles of 115-kV transmission line. The plant will consist of two (2) General Electric LM6000 PC Sprints gas turbine generators that will generate 95-MW under annual average atmospheric conditions. The LM6000 PC Sprints is a single gas turbine utilized to drive an electric generator. The modular power plant is equipped with a self-contained cooling system and inlet-air filtration system as well as air inlet and exhaust silencers. The control system is fully computerized and will be operated from the adjacent control room in GWF's Hanford cogeneration plant. The LM6000 PC Sprints are modular in design and will be installed with enclosures around the CTG and generator on foundations designed to Seismic Zone 3 standards and conforming to site soil conditions. The other structures are the air-inlet stack and the SCR and oxidation catalyst. These structures will be designed to conform with Seismic Zone 3 standards.

Small Power Plant Exemption Evaluation Process

The SPPE process allows projects between 50 and 100 MW to proceed with local approval rather than requiring an Energy Commission license. This exemption from the Energy Commission licensing process can be applied to projects that would not create a substantial adverse impact on the environment or energy resources. The Energy Commission acts as the lead agency under the California Environmental Quality Act (CEQA) and will prepare an Initial Study and Mitigated Negative Declaration that examines public health and safety, along with environmental impacts of the proposed project, including all related facilities such as electric transmission lines, natural gas and water pipelines. If the exemption is granted, the applicant would still need to secure the appropriate licenses and permits from relevant local, state, and federal agencies.
