When we all conserve, outages are preventable


  • 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. This summer, discover simple ways to conserve energy, save money and help ease the burden on the power grid.

Find your block and possible rotating outage period


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.

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.
