The California Independent System Operator (CAISO), the largest electricity grid in California, broke its own solar generation record on Tuesday of this week. The 8,030 megawatts put out at 1:06pm on Tuesday, July 12 were approximately double the 2014 high, and ~2,000 megawatts (MW) higher than last year’s record. Additionally, CAISO only accounts for ~80% of California’s electricity grid — just the Pacific Gas and Electric, Southern California Edison, and San Diego Gas and Electric jurisdictions. Smaller municipal utilities like Sacramento Municipal Utility District aren’t included.
