08/16/2021

PG&E’s Emergency Operations Center is Open and Company Meteorologists and Operations Professionals are Monitoring the Situation

The Majority of Affected Customers Would Be in Butte and Shasta Counties; PG&E Is Sending 48-Hour Notices to Customers Who Might Be Affected

SAN FRANCISCO--(BUSINESS WIRE)-- Pacific Gas and Electric Company (PG&E) opened its emergency operations center today, and the company’s meteorologists and operations professionals are monitoring a potential dry offshore wind event forecasted to start Tuesday evening (Aug. 17). Given this wind event and current conditions including extreme to exceptional drought and extremely dry vegetation, PG&E has begun sending 48-hour advance notifications to customers in targeted areas where PG&E may need to proactively turn power off for safety to reduce the risk of wildfire from energized power lines.

Potential Public Safety Power Shutoff Tuesday Night

The potential PSPS event starting Tuesday night could affect approximately 39,000 customers in small portions of 16 counties in the Sierra Nevada foothills, the North Coast, the North Valley and the North Bay mountains. While the majority of customers—about 27,000—are in Butte and Shasta counties, we are also notifying customers who may experience safety shutoffs in portions of 14 other counties: Glenn, Humboldt, Lake, Lassen, Mendocino, Napa, Plumas, Sierra, Solano, Sonoma, Tehama, Trinity, Yolo and Yuba.

The potential PSPS event is approximately 48 hours away and conditions may change. PG&E’s in-house meteorologists, as well as its Wildfire Safety Operations Center and Emergency Operations Center, continue to closely monitor conditions. We will share additional customer notifications as conditions evolve.

Customer notifications—via text, email and automated phone call—began Sunday evening, approximately two days prior to the potential shutoff. PG&E employees will pay individual, in-person visits when possible to customers enrolled in the company’s Medical Baseline program who do not verify that they have received these important safety communications, with a primary focus on customers who rely on electricity for critical life-sustaining equipment.

Public Safety Power Shutoffs: What PG&E Customers Should Know

Why PG&E Calls a PSPS Event

We initiate Public Safety Power Shutoffs (PSPS) when the weather forecast is for such severe weather that people’s safety, lives, homes and businesses may be in danger of wildfires.

As each weather situation is unique, we carefully review a combination of factors when deciding if power must be turned off. These factors include:

  • Low humidity levels, generally 30% and below.
  • A forecast of high winds, particularly sustained winds above 20 miles per hour and wind gusts above 30-40 miles per hour.
  • Condition of dry material on the ground and low moisture content of vegetation.
  • A Red Flag Warning declared by the National Weather Service.
  • Real-time ground observations from our Wildfire Safety Operations Center and from our crews working across the service territory.

This year, our decision-making process is evolving to also account for the presence of trees tall enough to strike power lines when determining if a PSPS event is necessary.

Every wildfire season is different, and the ongoing drought and the conditions will determine the number of times we will need to shut off power, without compromising safety.

This set of criteria is a first step which may lead to further analysis from our meteorology team to determine if a Public Safety Power Shutoff (PSPS) event is necessary.
