California Generates More Than 5% of Electricity from Utility-scale Solar

March 27, 2015 By Linda Hardesty

EIACalifornia has become the first state with more than 5 percent of its annual utility-scale electricity generation from utility-scale solar power, according to the Energy Information Administration.

California’s utility-scale (1 MW or larger) solar plants generated a record 9.9 million MWh of electricity in 2014, an increase of 6.1 million MWh from 2013. California’s utility-scale solar production in 2014 was more than three times the output of the next-highest state, Arizona, and more than all other states combined.

Several large plants were phased into operation in California during 2014, including two 550 MW solar photovoltaic plants, Topaz and Desert Sunlight (Phases 1 and 2), as well as the 377 MW Ivanpah (Phases 1, 2, and 3) and the 250 MW Genesis solar thermal plants. In total, nearly 1,900 MW of new utility-scale solar capacity was added, bringing the state’s utility-scale capacity for all solar technologies to 5,400 MW by the end of 2014.

California has promoted solar power through a series of state policies, including a renewable portfolio standard (RPS) that requires electricity providers to obtain 33 percent of the power they sell from eligible renewable sources by 2020. In 2014, the state obtained 22 percent of its electricity from nonhydropower renewables including wind, solar and biomass.

California also created incentives, including rebates and net-metering policies, to encourage rooftop and other small-scale solar capacity, whose generation is not captured in the above figure. By the end of 2014, more than 2,300 MW of small-scale solar capacity was installed on homes and businesses, according to the California Public Utilities Commission.
