When will a shutoff occur?

PG&E determines the shutoff in coordination with the National Weather Service to reduce the risk of PG&E lines staring a fire. Criteria is:

  • Temperatures over 80 degrees
  • Humidity less than 20% and poor overnight recovery from heat
  • Winds over 25 mph

PG&E will send an email to all registered customers 48 hours before a planned shutoff and again 24 hours before shutoff.  Shutoff involves turning off a transmission line. Transmission lines will shut down the area with a high fire danger and likely the surrounding communities.  You may wish to consider following the company's Twitter and Facebook pages.
