Pacific Gas and Electric Company (PG&E) confirmed that it has implemented the first phase of a Public Safety Power Shutoff (PSPS) across significant portions of its service area in response to a widespread, severe wind event.

The Public Safety Power Shutoff will occur in three phases, with the first phase impacting approximately 513,000 customers beginning at 12 a.m. Wednesday morning. Customer impacts will include: Amador, Butte, Calaveras, Colusa, El Dorado, Glenn, Humboldt, Lake, Marin, Mendocino, Napa, Nevada, Placer, Plumas, Shasta, Sierra, Solano, Sonoma, Tehama, Trinity, Yolo and Yuba.

The second phase of the Public Safety Power Shutoff will occur around 12:00pm on Wednesday afternoon, impacting service to approximately 234,000 customers in the following counties: Alameda, Alpine, Contra Costa, Mariposa, San Joaquin, San Mateo and Santa Clara.

A third phase is being considered for the southernmost portions of PG&E’s service area, impacting approximately 42,000 customers. Specific locations are still to be determined.

The decision to turn off power was based on forecasts of dry, hot and windy weather including potential fire risk. Based on the latest weather forecasts and models, PG&E anticipates that this weather event will last through midday Thursday, with peak winds forecasted from Wednesday morning through Thursday morning and reaching 60 to 70 mph at higher elevations.

“The safety of our customers and the communities we serve is our most important responsibility, which is why PG&E has decided to turn power off to customers during this widespread, severe wind event. We understand the effects this event will have on our customers and appreciate the public’s patience as we do what is necessary to keep our communities safe and reduce the risk of wildfire,” said Michael Lewis, PG&E’s senior vice president of Electric Operations.

How local customers can prepare

As part of these preparedness efforts, PG&E is asking customers to:

Update their contact information at pge.com/mywildfirealerts or by calling 1-866-743- 6589 during normal business hours. PG&E will use this information to alert customers through automated calls, texts, and emails, when possible, prior to, and during, a PSPS.

Plan for medical needs like medications that require refrigeration or devices that need power.

Identify backup charging methods for phones and keep hard copies of emergency contacts.

Build or restock your emergency kit with flashlights, fresh batteries, first aid supplies and cash.

Keep in mind elderly family members, younger children and pets. Information and tips including a safety plan checklist are available at pge.com/psps.

Continue to monitor PG&E’s new weather forecasting web page at pge.com/weather which is a dedicated page with weather forecasting information and a daily 7-day PSPS lookahead.

To support customers in the affected areas, PG&E has opened Community Resource Centers in several locations beginning on Wednesday morning. The centers are located at:
