Key Dates


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 is a 500 megawatt (MW) natural gas-fired, simple cycle electrical generating facility. The WCEP is a peaking facility designed to meet electric generation load during periods of high demand, and provide the fast-start capabilities needed to provide in-basin voltage support as needed and to help integrate renewable energy resources into the grid.

The WCEP uses reclaimed water for cooling and site landscape irrigation. The Rowland Water District supplies reclaimed water for the project from the San Jose Creek Wastewater Reclamation Plant. This water is supplied to the WCEP site via a pipeline connection to an existing reclaimed water pipeline at the corner of Bixby Drive and Chestnut Street. Potable water for drinking and sanitary uses is provided through a pipeline connection to a Rowland Water District water main in Bixby Drive, immediately adjacent to the project site. 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.

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.
