As California’s climate changes, fire season is becoming a year-long battle against stronger, faster wildfires. During high fire risk weather conditions, SDG&E may use Public Safety Power Shutoffs (PSPS), a last resort tool, to help prevent our electric system from starting a wildfire, keeping our local residents and communities safe.
We evaluate many factors before deciding to shutoff power. These factors may include: wind speeds, vegetation moisture, temperature, humidity, field observations by SDG&E crews and information from fire agencies. We monitor many of these factors using our utility-owned weather network, which includes weather stations near fire-prone areas.
If a PSPS is necessary, we communicate with public safety authorities, first responders and the affected communities. We communicate with our customers in advance of an event – 48 hours, 24 hours and again prior to shutting off power, where conditions allow. In addition to notifying customers directly, outage updates are provided through social media, local news, radio, our website, PSPS app, and some community partner organizations.
