Project Description

The Walnut Creek Energy Park (WCEP) site, an 11.48-acre parcel, is located at 911 Bixby Drive in the City of Industry, Los Angeles County, in an area zoned for industrial uses. The WCEP was certified by the California Energy Commission (CEC) in February 2008 and began commercial operation in May 2013.

The WCEP is a 500-megawatt (MW) natural gas-fired, simple cycle electrical generating facility, designed to meet electric generation load during periods of high demand (peak demand). WCEP also provides the fast-start capabilities needed to provide in-basin voltage support as needed and to help integrate renewable energy resources into the grid. WCEP operates five GE LMS100 simple-cycle gas turbines, each with an electrical generator and emissions equipment. As a simple-cycle configuration, there are no heat recovery steam generators, duct burners, or steam turbines.

The WCEP uses reclaimed water from the Rowland Water District for cooling and site landscape irrigation. Potable water for drinking and sanitary uses is also provided by the Rowland Water District. Sanitary wastewater is discharged to a Los Angeles County Sanitation District trunk sewer line that runs in a utility easement within the project site. Process wastewater is also discharged to this sanitary sewer line through a connecting pipeline to the trunk sewer line. The WCEP is connected to Southern California Edison's electrical system at the existing Walnut Substation, which is located approximately 250 feet south of the project site. Natural gas is supplied to the WCEP via a pipeline connection to a Southern California Gas Company high-pressure gas pipeline that runs in a utility easement within the WCEP parcel.

On March 16, 2021, Walnut Creek Energy, LLC filed a petition with the CEC seeking to modify the fuel and ammonia mixture for improved combustion efficiency, to result in a net increase in output of 17.4 MW.

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.
