SAN DIEGO (KGTV) -- California's energy operator have issued a statewide Flex Alert ahead of anticipated high temperatures this coming weekend.
The California Independent System Operator (ISO) is calling for voluntary electricity conservation, from 3 p.m. to 10 p.m. on Friday, Aug. 14.
"With high temperatures in the forecast, the power grid operator is predicting an increase in electricity demand, primarily from residential air conditioning use," the ISO said in a statement.
In San Diego, an Excessive Heat Warning will be in effect from noon Friday until 8pm Monday from the inland areas to the deserts. The heat will peak on Friday and Saturday with temperatures ranging 5 to 15 degrees above normal.
The above-normal temperatures and humidity will stick around through most of next week.
"Consumers are urged to conserve electricity, especially during the late afternoon and early evening, when the grid is most stressed due to higher demand and solar energy production falling. Consumers are also asked to turn off unnecessary lights, use major appliances before 3 p.m. and after 10 p.m., and set air conditioner thermostats to 78 degrees or higher," the ISO said.
• Set thermostat at 78° or higher
• Cool with fans and draw drapes
• Turn off unnecessary lights and appliances
• Use major appliances in morning or late evening
