Project Description

The Blythe Energy Project (BEP) is located in the city of Blythe, eastern Riverside County, approximately 5 miles from downtown Blythe.

BEP is a nominal 520-megawatt combined-cycle, natural gas-fired facility consisting of two combustion turbine generators, Units 1 and 2. The project incorporates selective catalytic reduction to reduce project emissions. Associated facilities include a 600-foot, 160/230 kilovolt electric overhead transmission line that interconnects to Western Area Power Administration’s (Western) existing Blythe Substation; a 0.8-mile natural gas fuel supply line that connects with the SoCal Gas Pipeline and an 11.5-mile natural gas fuel supply line that connects with the El Paso Gas Facility in Ehrenberg, Arizona; and onsite water supply wells and wastewater evaporation ponds.

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

On October 11, 2006, the California Energy Commission (CEC) approved a Post-Certification Amendment (TN 38159) for the 67-mile 230-kV generation intertie transmission line that allows BEP to deliver the full BEP electrical output to the California Independent System Operator-controlled electrical transmission system. The transmission line began operation on April 1, 2010.

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