GENERAL DESCRIPTION OF PROJECT

On March 5, 2002, the California Energy Commission (Energy Commission) approved a license (Original License) for the Henrietta Peaker Power Plant (HPP), a 95 megawatt (MW) natural-gas fired simple-cycle peaking facility in Henrietta, Kings County (GWF Henrietta Peaker).

The facility 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 Lemoore. 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 Energy Commission approved a petition 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 (GWF), the Energy Commission approved the project owner’s petition 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.

On April 13, 2016, ownership of the HPP was transferred GWF Energy LLC to AltaGas San Joaquin Energy Inc., and operational control of the HPP was transferred from Star West Generation Management Company to AltaGas Tracy Operations 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.
