This week, California experienced its first blackouts in nearly 20 years. On August 19, the California Independent System Operator (“CAISO”) issued another state-wide flex alert, calling on the public to reduce energy use to prevent rotating power outages. As the state’s heat wave enters its seventh day, the temperature in California today will again reach dangerous levels and will continue to strain the system. While the exact cause of the recent blackouts is under investigation, Assemblyman Jim Patterson pointed to the unreliability of renewable power and the state’s reduced dependence on natural gas.
CAISO called the events this week a “perfect storm,” caused by the heat wave and corresponding spike in demand, simultaneous loss of some sources of power, and inability to import out-of-state electricity. When the sun sets, electricity generated by solar facilities drops, removing thousands of megawatts of solar power from the system while demand, fueled by the record-breaking heat, remains high.
Despite allegations that renewables are unreliable, there is no indication
