Public Safety Power Shutoff (PSPS)

What is a PSPS Event?

When there are potentially dangerous weather conditions in fire-prone areas, power companies may call a Public Safety Power Shutoff (PSPS) event. During these events, power companies will proactively turn off power in high fire risk areas to reduce the threat of wildfires.

Elevated weather conditions can cause vegetation or other items to be blown into power lines possibly creating a wildfire. Under these situations, power companies may temporarily shut off power to customers to keep the community safe. Power companies consider a number of factors and conditions before declaring a PSPS. These include, but are not limited to:

  • High winds (including Red Flag Warnings declared by the National Weather Service)
  • Low humidity
  • Dry vegetation that could serve as fuel
  • On-the-ground observations
  • Fire threat to electric infrastructure
  • Public safety risk
