General Description of Project

In December 2003, the California Energy Commission approved the Inland Empire Energy Center (IEEC) project, an 810 megawatt (MW) combined-cycle facility located on approximately 46 acres in the City of Menifee, in Riverside County. The project site is bordered by McLaughlin Road to the south, San Jacinto Road to the east, Antelope Road to the west, and the Burlington Northern Santa Fe railway to the north.

In June 2005, the Energy Commission approved an amendment to change the power generation configuration for the originally proposed General Electric Company (GE) 7FB combustion turbine generator and one steam turbine generator to a new configuration using two GE S107H systems. Each GE S107H System has a steam turbine and gas turbine configured on a common shaft line driving a single generator.

The project connects the on-site switchyard to the existing Southern California Edison Valley substation located approximately one-mile east of the project site via a 500 kilovolt (kV) transmission line. The project also includes an 18-inch, 4.7-mile pipeline for the disposal of non-reclaimable wastewater. Sanitary wastewater is discharged to a 33-inch sewer line in McLaughlin Road. Natural gas is delivered to the facility via a Menifee Road 20-inch pipeline that connects to the existing Sempra Energy transmission lines located approximately one-mile east of the project site.

Unit 1 commissioning activities were completed in January of 2009, with Unit 2 completed in June 2010.

In 2009, the Energy Commission approved a petition to amend to transfer ownership of the 0.9 mile overhead 500-kV transmission line, connecting the Inland Empire Energy Center facility to the Valley Substation, to Southern California Edison.

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.
