When we all conserve, rotating outages are preventable

A rotating outage is an electric power outage that rotates from area to area, so no single neighborhood is down for very long. It’s designed to reduce demand and maintain power-grid reliability. Brief outages protect against longer and larger outages.

  • The California Independent System Operator (CAISO) decides when rotating outages are necessary to reduce demand on the power grid.
  • You may be notified by text, email and/or phone before PG&E enacts a rotating outage in your area. Outages typically last 1-2 hours.
  • Remember—all outage start times are estimates. They're meant as guidelines, not definitive schedules.
  • You can help prevent outages. Discover simple ways to conserve energy, save money and help ease the burden on the power grid.

Flex Alerts

Flex Alerts are part of a statewide program, also run by the CAISO. The purpose of a Flex Alert is to encourage customers to conserve as much energy as they can during a designated period. The CAISO typically calls a Flex Alert when statewide forecasts are trending higher than average. If customers conserve energy, rotating outages can be prevented.

Rotating outages: what to expect

NOTE: Shutoff times can be postponed or cancelled

When demand for electricity is higher than supply, such as during a heat wave, Californians might be asked to use less energy. If enough people conserve electricity at once, rotating outages can be cancelled or postponed by an hour or more.
