Sempra gets OK for power purchase agreements with Burbank, Los Angeles

The cities of Los Angeles and Burbank have approved a 20-year agreement to purchase 250 MW of solar power from Sempra U.S. Gas & Power’s proposed Copper Mountain Solar 3 project to be constructed in Boulder City, Nev., about 40 miles southeast of Las Vegas.

The Copper Mountain Solar 3 agreement provides the Los Angeles Department of Water and Power (LADWP) with the bulk of the power produced by the solar power plant – 210 MW – through an agreement with the Southern California Public Power Authority (SCPPA).

SCPPA is a joint powers authority consisting of 11 municipal utilities and one irrigation district that finances power and transmission resources on behalf of its members. LADWP is one of the members as is the city of Burbank. Burbank will purchase the remaining 40 MW.

Power will be delivered from the plant to Southern California through a substation and transmission lines operated by LADWP.

Construction on the 1,370-acre Copper Mountain Solar 3 project is expected to begin next month. At the height of construction, it will create approximately 300 new jobs. When completed in late 2015, the project will deliver enough clean electricity to power about 80,000 homes annually.

Copper Mountain Solar 3 and its two adjacent Copper Mountain Solar facilities in the Nevada desert will combine to create one of the largest solar power complexes in the Southwest.

Copper Mountain Solar 3 is the fourth utility-scale renewable energy project that Sempra U.S. Gas & Power has developed in Boulder City. When Copper Mountain Solar 3 is completed, the Boulder City solar projects will have a combined capacity exceeding 450 MW. Sempra U.S. Gas & Power has an additional 700 MW of solar power under development in Arizona and California.

Sempra U.S. Gas & Power, LLC is a leading developer of renewable energy and natural gas solutions. The company operates solar, wind and natural gas power plants that generate enough electricity for nearly 1 million homes, along with natural gas storage and pipelines, and distribution utilities.

Sempra U.S. Gas & Power is a unit of Sempra Energy, a Fortune 500 energy services holding company with 2011 revenues of $10 billion. The Sempra Energy companies’ nearly 17,500 employees serve about 31 million consumers worldwide.
