California Sets New Record for Solar Power Generation of Over 2,000 MW

LCG, June 14, 2013--The California Independent System Operator (ISO) announced that a new record was set for solar power output of 2,071 MW at 12:59 p.m. on June 07, 2013. According to the ISO, the peak demand was approximately 36,000 MW, and solar generation provided more than five percent of the demand for electricity.

The California ISO President and CEO stated, "This new record is remarkable considering the amount has more than doubled since last September when solar peaked at 1,000 megawatts. We are excited by this trend and expect to hit more record peaks on a regular basis."

California leads the nation in solar power. California's Renewables Portfolio Standard (RPS) was originally established by legislation in 2002, and subsequent amendments have led to requirement for California?s electric utilities to have 33 percent of their retail sales served by eligible renewable energy resources in 2020 and all subsequent years. Interim targets for the utilities are 20 percent of retail sales by December 31, 2013, and 25 percent by December 31, 2016.
