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

As required by the Warren-Alquist Act, the Energy Commission monitors Commission-certified energy projects throughout construction, operation, and closure to ensure compliance with the conditions of certification imposed by the Commission’s Final Decision for approving the projects.
