The Hanford Energy Park Emergency Peaker Project (HEPP) is facility located approximately three miles south of the City of Hanford, Kings County.
The HEPP is a 95-megawatt natural-gas fired simple-cycle peaking facility consisting of two aero-derivative General Electric LM6000 combustion turbine-generator sets operating in simple-cycle mode equipped with dry, low oxides of nitrogen combustors and steam injection capability. The HEPP presently uses up to 150 acre-feet per year of groundwater from a well located on the project owner’s adjacent cogeneration plant for plant cooling and other uses.
On March 24, 2010, the California Energy Commission (CEC) approved a Post-Certification Amendment (PCA) (TN 56497) amending the license to allow the conversion of the GWF Hanford Peaker to a combined-cycle facility known as the GWF Hanford Combined-Cycle Power Project. The project was never converted.
On November 17, 2014, the CEC approved a PCA (TN 203379) requesting the revocation of the 2010 Amended Final Decision for the GWF Henrietta Combined-Cycle Power Plant, and the reinstatement and extension of the original 2001 Hanford Energy Park Emergency Peaker Project certification.

Power Plant Certification and Exemption Processes
The CEC has the exclusive authority to certify all thermal power plants 50 megawatts (MW) and larger and related facilities proposed for construction in California. The Application for Certification (AFC) process is a certified regulatory program under the California Environmental Quality Act (CEQA). As a certified regulatory program, the CEC does not prepare environmental impact reports (EIRs) in an AFC proceeding, but instead prepares environmental assessment documents that are functionally equivalent to EIRs. A certificate issued by the CEC is in lieu of any permit, certificate, or similar document otherwise required by any state, local or regional agency, or federal agency to the extent permitted by federal law, and supersedes any applicable statute, ordinance, or regulation of any state, local, or regional agency, or federal agency to the extent permitted by federal law.
