Potential Sunday/Oct. 25 PSPS Event

Forecasted Highest Winds and Driest Conditions of the Season Mean PG&E May Need to Proactively Turn Off Power for Safety to Approximately 466,000 Customers Across Northern and Central California - Seite 2

Customer Notification and Impact

The potential PSPS event is still two days away. PG&E in-house meteorologists as well as staff in its Wildfire Safety Operation Center and Emergency Operation Center will continue to monitor conditions closely, and additional customer notifications will be issued as we move closer to the potential event.

Customer notifications—via text, email and automated phone call—began late this afternoon, approximately two days prior to the potential shutoff. Customers enrolled in the company’s Medical Baseline program who do not verify that they have received these important safety communications will be individually visited by a PG&E employee with a knock on their door when possible. A primary focus will be given to customers who rely on electricity for critical life-sustaining equipment.

It is very possible that customers may be affected by a power shutoff even though they are not experiencing extreme weather conditions in their specific location. This is because the electric system relies on power lines working together to provide electricity across cities, counties and regions.
