FAQs for Power Shutoffs


A Public Safety Power Shutoff is the name that the utility Pacific Gas and Electric (PG&E) uses to describe a proactive shutoff of electricity.  PG&E may declare a PSPS if some of the following weather conditions exist:

  • A Red Flag Warning
  • Low humidity levels
  • Forecasted sustained winds generally above 25 miles per hour and wind gusts in excess of approximately 45 miles per hour
  • Dry fuel conditions


If your electricity has been shut down due to a PSPS, PG&E has opted to preemptively shut off electrical transmission along power lines that the utility has deemed to be unsafe due to current weather conditions.

As defined by the National Weather Service, a Red Flag Warning means any combination of warm temperatures, very low humidities, dry fuels, the possibility of dry lightning strikes and strong winds that are expected to produce an increased risk of fire danger.

In order for PG&E to restore power after a PSPS event, first the utility is required to inspect the lines to determine if they have been damaged in the course of the shutoff. To accomplish this, PG&E uses helicopters and ground teams. The time to inspect the lines can vary, but in most cases, power will be restored within 12 daylight hours after severe weather has passed.
