Project Description

The Henrietta Peaker Power Plant (HPP) is located adjacent to Pacific Gas & Electric’s 70 kilovolt (kV) Henrietta Substation approximately one mile south of Highway 198 on 25th Avenue southeast of the City of Lemoor, Kings County.

HPP is a nominal 95-megawatt (MW) natural-gas fired, simple-cycle peaking facility consisting of two GE LM6000 natural gasfired combustion turbine generator (CTG) units.

HPP was placed in service on July 1, 2002, and initially operated under terms and conditions of a Power Purchase Agreement (PPA) with the California Department of Water Resources (DWR). The DWR PPA was subsequently novated and replaced by a PPA with Pacific Gas and Electric (PG&E) for operation of the HPP in simple cycle mode. The HPP currently operates under the terms and conditions of the PG&E PPA.

The HPP is approved to use up to 158 acre-feet per year of water for plant operations. The source of this water is from the federal Valley Project and State Water Project allocations purchased through Kings County. The project also utilizes a permanent, single-pass reverse osmosis system for water deionizing treatment.

On March 24, 2010, the California Energy Commission (CEC) approved a Post-Certification Amendment (PCA) (TN 56498) allowing the conversion of the simple-cycle Henrietta Peaker Project to the 120 MW GWF Henrietta Combined-Cycle Power Plant by adding two once-through steam generators to recover heat from the exhaust of the existing turbines and produce steam to power a new 25 MW steam turbine generator. The project was never converted.

On November 17, 2014, GWF Energy, LLC , the CEC approved a PCA (TN 203380) requesting the revocation of the 2010 Amended Final Decision for the GWF Henrietta Combined-Cycle Power Plant, and the reinstatement of the original 2002 certification to operate the facility as the simple-cycle Henrietta Peaker Project, allowing the continued operation of the Henrietta Peaker Project in compliance with the original 2002 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.
