Southern California Ed wins okay for three power deals with large solar projects

The California Public Utilities Commission at its March 12 meeting, in a unanimous vote, approved a single resolution covering three solar power purchase agreements (PPAs) worked out by Southern California Edison (SCE).

The utility won commission approval of three PPAs with Silver Ridge Power8minutenergy Renewables LLC and Copper Mountain Solar 4 LLC. This resolution approves cost recovery for the long-term agreements between SCE and:

  • Silver Ridge Power and 8minutenergy Renewables for the Mount Signal Solar Farm II and Mount Signal Solar Farm V projects. The Mount Signal II and V projects are located in southern Imperial County, approximately two miles west of the City of Calexico, California, and will have a capacity of about 154 MW and 252 MW respectively; and
  • Copper Mountain Solar 4 for the Copper Mountain project. It is located in Boulder City, Nevada, and will have a capacity of 94 MW.

All three photovoltaic projects resulted from SCE’s 2013 renewable portfolio standard (RPS) solicitation and all three PPAs were executed in July 2014. Mount Signal II has a targeted commercial operation date of June 1, 2020. Mount Signal V’s commercial operations target is Feb. 1, 2019. Copper Mountain is Jan. 1, 2020. The generation from all three projects could count towards SCE’s RPS requirements in Compliance Period 2017-2020.

The Mount Signal II and V facilities are being developed by Silver Ridge Power and 8minutenergy. Silver Ridge Power is experienced in developing, financing, constructing, and operating large scale PV projects. 8minutenergy is an experienced developer in California focusing on land acquisition and interconnection for solar projects. The joint team completed development of the 200-MW Mount Signal Solar Farm I project that began generating in May 2014. The Copper Mountain facility is being developed by Sempra U.S. Gas & Power, a wholly-owned subsidiary of Sempra Energy. Sempra U.S. Gas & Power has successfully developed a number of power plants throughout the United States.

The Mount Signal II and V solar facilities will interconnect at San Diego Gas and Electric’s (SDG&E) Imperial Valley substation. The Copper Mountain facility will interconnect at the Merchant Substation, which is jointly owned by SDG&E and NV Energy.
