California heat brings energy conservation 'Flex Alert'

Posted: Updated:

SAN DIEGO (CNS) - The manager of the state's power grid extended a statewide Flex Alert through Thursday, urging residents to conserve energy in response to high temperatures, power plant outages and reductions in transmission-line capacity.
   
The alert by the California Independent System Operator asks residents to cut back their power use, especially during peak hours of 2 to 9 p.m. The alert was initially issued only for Wednesday, but Cal-ISO later extended it through today.
   
"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.
   
The agency recommended that people conserve energy by setting thermostats at 78 or higher; using fans and closing drapes; turning off unnecessary lights and appliances; and using major appliances only in the morning or late evening.
   
Today's highs are forecast to be in the high 80s in San Diego, the high 90s in San Diego County valleys, and more than 115 in San Diego County deserts.
