California's Largest Utilities Hit 18% Renewables in 2010
March 8, 2011
California's three large investor-owned utilities (IOUs) collectively served 18% of their 2010 retail electricity sales with renewable power in 2010, according to the California Public Utilities Commission (CPU). The three are: Pacific Gas and Electric Company with 17.7%; Southern California Edison with 19.4%; and San Diego Gas and Electric Company with 11.9%. The previous year, they totaled 15% of sales from renewables.
The CPUC's Renewables Portfolio Standard (RPS) program, one of the most ambitious in the United States, requires IOUs, community choice aggregators, and electric service providers operating in California to obtain 20% of their retail sales from renewable energy sources by 2010. However, CPUC implemented flexible compliance rules that allow companies to bank excess renewable energy and defer deficits in any year for up to three years when using an allowable justification. The CPUC estimates that the IOUs will reach 20% before the end of 2012. CPUC will make a compliance determination after the California Energy Commission issues a Verification Report verifying the renewable energy claims. See the CPUC RPS website.
