Californian utility San Diego Gas & Electric (SDG&E) has finalised three new renewable power purchase agreements (PPAs) for 47MW of solar energy.
Two of the projects top 20MW – one being built by E.ON Climate and Renewables in Kern County, another by Silverado Power in San Diego County.
A smaller 7MW solar plant, also in San Diego County, will be built by Northlight Power.
SDG&E said that in 2012, for the second year in a row, it had surpassed the 20% mark in renewable power in proportion to overall power sales.
In 2011 and 2012 the company said it signed 36 PPA renewable energy contracts worth a total of 1,750MW of generation capacity.
“After starting with less than 1% energy in 2002, SDG&E put an aggressive course of action in place to obtain competitively priced renewable power for our customers to meet California's renewable requirements,” said James Avery, SDG&E senior vice president of power supply.
“This has resulted in a well-balanced renewable portfolio that encompasses a broad spectrum of energy sources including solar, wind, biomass, biogas and geothermal energy.”
