Southern California Edison works out revised deal for Copper Mountain 4 solar project

Southern California Edison on Aug. 4 filed with the Federal Energy Regulatory Commission an amended transmission owner upgrade agreement worked out with the California ISO (CAISO) covering a 92-MW solar project of Copper Mountain Solar 4 LLC.

The agreement describes the project as: “All equipment and facilities comprising the Interconnection Customer’s 92 MW solar photovoltaic Copper Mountain Solar 4 generating facility in Boulder City, Nevada, as disclosed by the Interconnection Customer in its Interconnection Request, as may have been amended during the Interconnection Study process, which consists of (i) of a solar photovoltaic facility, with a total maximum net electrical output to the CAISO Controlled Grid of 92 MW (ii) the associated infrastructure, (iii) meters and metering equipment, and (iv) appurtenant equipment, as further described in the GIA.”

The Copper Mountain Solar 4 project is to be interconnected at the San Diego Gas and Electric Merchant 230-kV Switchyard. The proposed commercial operation date is Sept. 1, 2016.

A project developer contact is: Copper Mountain Solar 4 LLC c/o David Grazda Director-Asset Management, Sempra U.S. Gas & Power, 488 8th Ave. HQ11S3 San Diego, CA 92101, Phone: (619) 696-4425.

Said the Sempra website about the most recent phase of this larger project to go on-line: “Copper Mountain Solar 3 is jointly owned by Sempra U.S. Gas & Power and Consolidated Edison Development. It is the third phase of the landmark Copper Mountain Solar complex, currently one of the largest photovoltaic (PV) solar facilities in the U.S. Situated on about 1,400 acres of land, Copper Mountain Solar 3 taps into the intense desert sun in Boulder City, Nevada to produce clean energy and a stronger local economy. The 250-megawatt (MW) facility was completed in 2015, generating enough clean electricity to power about 80,000 homes. The project provided a boost to the local economy, creating about 500 construction jobs at peak and four positions to operate the facility. The renewable power from the facility is sold to the Southern California Public Power Authority.”

The 58-MW Copper Mountain Solar 1 was completed in December 2010, and the 150-MW Copper Mountain Solar 2 was completed in 2012 (92 MW portion) and 2015 (the remaining 58 MW).
