SDG&E cut power to large areas of San Diego County and southern Orange County on Friday night to handle a surge in electricity need caused by the start of a heat wave that will last well into next week.The rolling failures 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 consumers. It was the very first time because 2001 that the California Independent System Operator, which runs the state power grid, had actually asked SDG&E to impose rolling failures. CAL-ISO “directed SDG&E to start turning, one-hour service disturbances (rotating blackouts) through its service area in San Diego and southern Orange counties,” the energy stated.
The first set of outages hit at around 6:40 p.m. and impacted 28,000 consumers, according to Helen Gao, an SDG&E spokesperson.
Through roughly 7:40 p.m, the affected neighborhoods 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 brought back to the very first block of clients at roughly the exact same time.The utility initiated a second round of blackouts at around 7:45 p.m. The failures took place on a day when daytime temperature levels ranged from the 80s at the coast to 120 degrees at Borrego Springs. The National Weather System says that the county will be abnormally warm on Friday night and that the heat wave will continue on Saturday.
CAl-ISO stated the heat wave in California plus record heat in the Southwest combined to worry the grid. CAL-ISO representative Anne Gonzales stated it didnt appear likely that more rolling interruptions would be needed on Saturday.The power shortage is being driven by what officials state is among the worst statewide heat waves in years, The broiling conditions that started Friday in California may equal the fatal seven-day heat event of July 2006, the National Weather Service stated.
