Californians are being asked to conserve power between 2 p.m. and 9 p.m. due to high temperatures. The alert was initially issued only for today, but the California Independent System Operator Corp. later extended it through Thursday.

"Electricity supplies statewide are expected to be tight because of high summer temperatures driving up demand, power plant outages and transmission line import capacity reductions," according to Cal-ISO. "Power imports may be limited today because of high temperatures in neighboring states."


Cal-ISO officials said conservation is especially important in the late afternoon, when air-conditioning use tends to push electricity use to its highest point of the day.

According to the National Weather Service, temperatures are expected to reach 76 in San Diego, 82 at Camp Pendleton, 81 in Vista and 82 in Chula Vista.
