Key Dates


On August 17, 2001, Inland Empire Energy Center, LLC (IEEC) filed an Application for Certification with the California Energy Commission (Energy Commission) seeking approval to construct and operate the Inland Empire Energy Center. On March 11, 2005, the Energy Commission received a petition from IEEC to amend the Energy Commission Decision for the Inland Empire Energy Center Power Project.The amended project is located on approximately 46-acres in the city of Menifee, within 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.

The new configuration consists of two GE 107H combined-cycle systems (H System). The H System represents GE's latest gas turbine technology providing superior fuel economy and environmental performance. The net energy center power output, after taking away auxiliary loads of 20 MW, is approximately 790 MW. 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 new 500 kV transmission line. The project also includes the construction of a new 18-inch, 4.7-mile pipeline for the disposal of non-reclaimable wastewater. Sanitary wastewater would be discharged to an existing 33-inch sewer line in McLaughlin Road. The project will use up to 5,000 acre feet per year of recycled water as it is available; initially, raw water would supplement the use of recycled water until it is widely available.

Natural gas is delivered to the facility via Menifee Road pipeline; a new 20-inch pipeline that connects to the existing Sempra Energy transmission lines located approximately one-mile east of the project site.

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.
