SAN FRANCISCO, Calif. September 7, 2020 – Pacific Gas and Electric Company (PG&E) has begun the process of power de-energization of numerous electrical lines as part of a Public Safety Power Shutoff (PSPS) due to severe weather conditions. The PSPS event will affect customers in portions of 22 counties in the northern Sierra foothills, northern Sacramento Valley, and elevated North Bay terrain. This PSPS event is based on forecasts of widespread, severely dry conditions and strong, gusty winds that create critical fire weather with high ignition risk. These conditions are expected to continue through Wednesday morning.

The power shutoff is expected to impact approximately 172,000 customers in portions of 22 counties and 7 tribal communities, including: Alpine, Amador, Butte, Calaveras, El Dorado, Humboldt, Kern, Lake, Lassen, Mariposa, Napa, Nevada, Placer, Plumas, Shasta, Sierra, Siskiyou, Sonoma, Tehama, Trinity, Tuolumne and Yuba.

PG&E will be able to use temporary generation and islanding to enable about 69,000 customers and several medical facilities to stay energized.

For a list of affected customer counts and cities per county, see www.pge.com/pspsupdates.

We are working to improve our PSPS program by making events smaller in size, shorter in length and smarter for our customers. Although the National Weather Service has placed 1.5 million customers across our service territory under Red Flag Warning conditions, we have been able to limit public safety PSPS de-energization to less than 12% of those customers now under Red Flag Warning risk. While PSPS is an important wildfire safety tool, we understand the burden PSPS places on our customers especially for those with medical needs and customers sheltering-at-home in response to the novel coronavirus (COVID-19). We are working to reduce the number of customers affected and the length of time they are without power.

Timeline for safety shutoffs

The process to shut off power began at around 9 p.m. today, Monday, Sept. 7, 2020.

  • Forecasts indicate the peak period of Diablo winds should occur beginning at 10 p.m. on Monday through Wednesday morning.
  • Once the high winds subside, PG&E will inspect the de-energized lines to ensure they were not damaged during the wind event, and then restore power. PG&E will safely restore power in stages as quickly as possible, with the goal of restoring power to nearly all customers within 12 daylight hours after severe weather has passed.

Customer notifications—via text, email and automated phone call—began late Saturday afternoon, approximately 48 hours 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 to deliver the warning if possible, starting with customers who rely on electricity for critical life-sustaining equipment.
