Sempra, Con Edison mark completion of 250-MW Copper Mountain Solar phase

Various dignitaries on April 30 joined project owners Sempra U.S. Gas & Power and Consolidated Edison Development to dedicate the 250-MW Copper Mountain Solar 3 facility in Boulder City, Nev.

Situated on 1,400 acres, Copper Mountain Solar 3 is the third phase of the Copper Mountain Solar complex, currently among the largest photovoltaic (PV) solar power installations in the U.S. The entire complex, which also includes the recently completed 58-MW second phase (Copper Mountain Solar 2), is capable of generating more than 450 MW.

“Copper Mountain Solar is an excellent example of economic diversification through the advancement of clean energy generation, further solidifying Nevada as a sustainable energy leader,” said Paul Thomsen, director of the Nevada Governor’s Office of Energy. “Sempra U.S. Gas & Power and Consolidated Edison Development have made a significant investment in Nevada, demonstrating cooperation, collaboration and leadership in the west’s energy industry.”

“Copper Mountain Solar 3 is our largest solar project to date, and we are pleased to be joined by state and local leadership, as well as members of the Boulder City community, to celebrate this significant milestone,” said Patti Wagner, president and CEO of Sempra U.S. Gas & Power. “We look forward to continued partnership and collaboration with Boulder City as we prepare to break ground on the next phase of the Copper Mountain Solar complex, Copper Mountain Solar 4, later this year.”

“ConEdison Development is proud of the relationship it has cultivated with Sempra U.S. Gas & Power and we’re honored to dedicate the 250-megawatt Copper Mountain Solar plant,” said Mark Noyes, senior vice president and chief operating officer of ConEdison Development. “We look forward to continue working with Sempra U.S. Gas & Power to building a cleaner environment and greener future.”

Construction on Copper Mountain Solar 3 began in 2013 and was completed in early 2015. The completion of Copper Mountain Solar 3 brings Sempra U.S. Gas & Power’s jointly-owned operating solar power portfolio up to 660 MW.  

Sempra U.S. Gas & Power is a leading developer of renewable energy and natural gas solutions with power plants that generate enough electricity for nearly 600,000 homes. Sempra U.S. Gas & Power companies also operate natural gas storage facilities, pipelines and distribution utilities. The company is a subsidiary of Sempra Energy (NYSE: SRE).

Con Edison Development has built a robust pipeline of renewable energy projects and opportunistically grown its portfolio to more than 550 MW as of year-end 2014. Con Edison Development is a subsidiary of Consolidated Edison (NYSE: ED), one of the nation’s largest investor-owned energy companies, with approximately $13 billion in annual revenues and $44 billion in assets.

The California Public Utilities Commission at its March 12 meeting 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. The Copper Mountain facility is being developed by Sempra U.S. Gas & Power, the commission noted.
