Statewide Flex Alert

Prepare for Possible Rotating Outages

The California Independent System Operator (ISO) issued a statewide Flex Alert, a call for voluntary electricity conservation, today and extending through Wednesday, August 19. The Flex Alerts are in effect from 3 p.m. to 10 p.m. each day.

A persistent, record-breaking heatwave in California and the western states is causing a strain on supplies. Consumers should be prepared for likely rolling outages during the late afternoons and early evenings through Wednesday. There is not a sufficient amount of energy to meet the high amounts of demand during the heatwave.

Rotating outages caught more than 270,000 Californians off guard over the weekend, with some areas losing electricity for up to an hour.

The California Independent System Operator (CAISO) has a suggested energy management plan on its FlexAlert website. Additional information can be found here.

Flex Alerts

A Flex Alert is issued by the ISO when the electricity grid is under stress because of generation or transmission outages, or from persistent hot temperatures.

Consumers should voluntarily conserve electricity to help avoid more serious steps to protect the power grid, including local rotating outages.
