A 5.7 magnitude earthquake centered south of San Diego was felt as far north as Los Angeles this week, but there were no reports of power outages or damage to grid equipment caused by the tremor. The quake that struck Monday evening was the largest of about two dozen tremors that hit southern Imperial and San Diego counties near the U.S.-Mexican border over the span of a few days. But despite the size of Monday’s tremor, the San Diego area came through it virtually unscathed. “At this time we do not have any reports of outages or damages,” San Diego Gas & Electric spokesperson April Sharp said the day after the quake. Sempra Generation’s 625 MW Termoelectrica de Mexicali sustained no damage, according to spokesperson Scott Crider. “We came through this one unscathed.” He added after the last earthquake it took several weeks to repair damage. The other tremors, which ranged in magnitude from 3.2 to 4.1 and also were concentrated in the same general area, are believed to be aftershocks of the 7.2 magnitude quake that rocked much of Southern California two months ago. When that quake struck April 4, one power station, InterGen’s 1,065 MW La Rosita plant, was affected. The four-unit facility, located about 38 miles from the epicenter, suffered some damage in its switchyard. It was not impacted by the most recent quake. “La Rosita did not suffer any ill effects as a result of the earthquake,” InterGen spokesperson Corbie Kiernan stated. The quake was reportedly felt as far north as parts of Los Angeles, but as was the case closer to the border, no power issues were reported. “We did not experience any outages as a result of the earthquake near San Diego and our system is functioning normally,” said Los Angeles Department of Water & Power spokesperson Gale Harris. A California Independent System Operator spokesperson also stated it had received no reports of outages or damages to the energy grid.
