FOLSOM, Calif. — The California Independent System Operator has issued a statewide Flex Alert, a call for voluntary electricity conservation, from 3 to 10 p.m. on Oct. 15.

With high temperatures in the forecast, the power grid operator predicts an increase in electricity demand, primarily from air conditioning use.

The residents of California are urged to conserve electricity, especially during these peak hours.

Conservation tips include:
• Before 3 p.m., “pre-cool” buildings by setting air conditioning thermostats lower than usual; also, charge electronic devices and electric vehicles; and run dishwashers, washers and dryers, and other major appliances.

• After 3 p.m., set the thermostat at 78° or higher

• Cool with fans and draw drapes

• Turn off unnecessary lights and defer use of appliances
