SDG&E cut power to big locations of San Diego County and southern Orange County on Friday night to cope with a surge in electrical power need caused by the start of a heat wave that will last well into next week.The rolling interruptions started at 6:40 p.m. and ended soon after 8 p.m., SDG&E said. The blackouts impacted about 58,700 of the energys clients. It was the very first time because 2001 that the California Independent System Operator, which runs the state power grid, had asked SDG&E to enforce rolling failures. CAL-ISO “directed SDG&E to start turning, one-hour service disturbances (turning interruptions) through its service area in San Diego and southern Orange counties,” the energy stated.
The first set of failures struck at around 6:40 p.m. and affected 28,000 consumers, according to Helen Gao, an SDG&E spokesperson.
Through roughly 7:40 p.m, the impacted communities included parts of Escondido, Carmel Valley, Mission Valley, Sorrento, Ocean Beach, Torrey Pines, El Cajon, Solana Beach, Kearny Mesa, Lake Murray, Tierrasanta, and Scripps Ranch. Power also was out in parts of Dana Point and San Clemente in southern Orange County.
SDG&E said power was restored to the first block of clients at roughly the very same time.The energy initiated a second round of failures at around 7:45 p.m. The blackouts occurred on a day when daytime temperature levels varied from the 80s at the coast to 120 degrees at Borrego Springs. The National Weather System states that the county will be unusually warm on Friday night and that the heat wave will continue on Saturday.
CAl-ISO said the heat wave in California plus record heat in the Southwest combined to stress the grid. CAL-ISO spokesperson Anne Gonzales said it didnt appear likely that more rolling interruptions would be needed on Saturday.The power scarcity is being driven by what authorities say is one of the worst statewide heat waves in years, The broiling conditions that began Friday in California may rival the fatal seven-day heat event of July 2006, the National Weather Service stated.
