“With high temperatures in the forecast, the power grid operator predicts an increase in electricity demand, primarily from air conditioning use,” CAISO said in a statement.

Californians are urged to voluntarily follow conservation measures including turning off unnecessary lights, delaying the use of major appliances until after 10 p.m. and setting air conditioner thermostats to 78 degrees or higher.

The Flex Alert comes as the Bay Area is expected to see high temperatures soaring into the 80s and 90s along the coast and into the 100s inland on Thursday and Friday, with conditions remaining mild overnight. The National Weather Service has declared a Heat Advisory for the region from 11 a.m. Thursday through 9 p.m. Friday.

Along with the heat, expected strong offshore winds has increased the danger for wildfires. A Red Flag Warning has been declared for the North Bay and East Bay hills and valleys, along with the Santa Cruz Mountains through 11 a.m. Friday.
