San Francisco, August 8, 2011 — Pacific Gas and Electric Co. and Sempra Generation, a unit of San Diego-based Sempra Energy, entered into a 25-year contract for 150 MW of renewable power from an expansion of Sempra Generation's Copper Mountain Solar complex in Boulder City, Nev.
The first 92 MW of solar panels at Copper Mountain Solar 2 are slated for installation by January 2013, with the remaining 58 MW slated for completion by 2015. Under the terms of the contract, PG&E has the option to accelerate the commercial operation date of the second phase.
Construction on the 1,100-acre solar plant is expected to begin in early 2012. Copper Mountain Solar 2 will produce enough zero-emission electricity to power about 45,000 homes when fully developed.
Sempra Generation and First Solar have previously teamed-up on the construction of two other large-scale solar projects in Nevada, including Copper Mountain Solar 1. The 48-MW installation was completed in late 2010 and is currently the largest PV solar power plant in the U.S. PG&E is currently delivering the power produced at the plant to its customers.
The power supply contract between Sempra Generation and PG&E is subject to approval by the California Public Utilities Commission.
