Key Dates


The original Blythe Energy Project (BEP) was licensed by the Energy Commission on March 21, 2001 and started commercial operation in December of 2003. The Blythe Energy Project Transmission Line (BEPTL) modifications project was certified on October 11, 2006, amending the Energy Commission Decision and modifying the generation facility to develop two new transmission lines and add a substation for the existing BEP located in the City of Blythe, Riverside County.

The BEPTL is a 67 mile 230-kV generation intertie transmission line to allow for delivery of the full BEP electrical output to the California Independent System Operator (CAISO)-controlled electrical transmission system.

The BEP is directly connected to the Buck Boulevard Substation, owned by Western Area Power Administration (Western), which in turn is connected to the Blythe Substation and the Southern California Edison Company (SCE) transmission system via the Metropolitan Water District’s Julian Hinds Substation.

The original BEP Application for Certification was reviewed by Energy Commission staff and the Western, the lead Federal agency. The subsequent major amendment (BEPTL) review was conducted by Energy Commission staff, Bureau of Land Management (BLM), and Western. BLM and Western acted as co-lead federal agency participants in the amendment review process and for National Environmental Policy Act (NEPA) compliance. The two federal agencies, the BLM and Western, had control over portions of the existing BEP transmission system and a portion of the proposed right-of-way for the transmission lines. The Energy Commission and BLM were notified in February 2008 that Western would no longer be a participant in the BEPTL Project; therefore, Western no longer has an action to address under NEPA, or any other involvement with the project.

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.
