Forecasts Indicate Potential for Historic Wind Event This Weekend; Approximately 850,000 Customers Notified that They May Be Impacted Beginning Saturday Evening

May Need to Proactively Turn Off Power for Safety in Portions of 36 Counties; Mutual Aid Request for 1,000 Personnel for Restoration Phase

Release Date: October 25, 2019
Contact: PG&E External Communications (415) 973-5930

SAN FRANCISCO, Calif.— Pacific Gas and Electric Company (PG&E) today said it continues to monitor a potentially powerful and widespread dry, hot and windy weather event expected to begin impacting the service area Saturday between 6 and 10 p.m. and lasting until midday Monday.

PG&E will need to turn off power for safety several hours before the potentially damaging winds arrive. It's important to note that as this weather system sweeps from north to south over a period of two days, PG&E customers across Northern and Central California will feel the effects of hot, dry winds at different times, which means outage times will vary, as well.

The potential Public Safety Power Shutoff (PSPS) is expected to affect approximately 850,000 customers and may impact portions of 36 counties across portions of Humboldt, the Sierra foothills, Western Sacramento Valley, North Bay, and across the greater Bay area, Monterey Bay and northern Central Coast on Saturday, Oct. 26. Customers in the southern-most portion of PG&E's service area in Kern County could have power shut off for safety on Sunday, Oct. 27.

Predictive data models indicate the weather event could be the most powerful in California in decades, with widespread dry Northeast winds between 45-60 miles per hour (mph) and peak gusts of 60-70 mph in the higher elevations.

Winds of this magnitude pose a higher risk of damage and sparks on the electric system and rapid wildfire spread. The fire risk is even higher because vegetation on the ground has been dried out by recent wind events.

Given the forecast and conditions, PG&E is advising its customers of the potential for a widespread PSPS lasting several days, intended to prevent a catastrophic wildfire. As this intense weather event approaches the service area in the next 24 hours, PG&E's forecasts will offer sharper detail, noting that the scope may continue to change on the number of customers who will be affected.

Shutoffs Could be Widespread and Extended

As experienced earlier in October, portions of most counties in PG&E's 70,000-square-mile service area could be temporarily de-energized, potentially including all Tier 2 and Tier 3 fire risk regions. Customers can view the fire threat maps on the California Public Utilities Commission website to know whether they live in one of these high fire-risk regions.

Customers should prepare for a shutoff lasting 48 hours or longer, given the long duration of the wind event. Power cannot be restored until the dangerous weather has passed, safety inspections of de-energized lines are complete, and damage to the system has been repaired.

"We understand that a longer shutoff would be very difficult for our customers. We are already working to minimize the length, including amassing a force of field personnel from PG&E, plus contractors and other utility companies, to be ready to tackle the inspection, repair and restoration process as soon as the weather passes," said PG&E Corporation CEO and President Bill Johnson.

Customer Notifications

The company provides direct notifications to affected customers who have given their contact information to PG&E 48 hours in advance of the potential shutoff, and again at 24 hours and four hours before shutoff.

PG&E has not determined whether to move forward with a shutoff, but will continue to monitor weather conditions and provide more definitive information on the potential timing and scale of shutoffs as weather models are updated.

Forecasts and Criteria for Shutoff

"The upcoming wind event has the potential to be one of the strongest in the last several years. It's also likely to be longer than recent wind events, which have lasted about 12 hours or less," said Scott Strenfel, Principal Meteorologist with PG&E.

PG&E's meteorology team is part of a group of fire weather experts and data scientists at the company who work closely with the National Weather Service and the National Interagency Fire Center's (NIFC) Geographic Area Coordination Center.

The company carefully reviews a combination of many criteria before taking steps to shut off power for safety, including but not limited to:

  • Low humidity levels, generally 20 percent and below.
  • Forecasted sustained winds generally above 25 mph and wind gusts in excess of approximately 45 mph, depending on location and site-specific conditions such as temperature, terrain, vegetation and local climate.
  • Moisture content: Condition of dry fuel on the ground and live vegetation (dead and live fuel moistures).
  • On-the-ground, real-time observations from PG&E's Wildfire Safety Operations Center and field crews.
  • A Red Flag Warning declared by the National Weather Service.
  • Information from the NIFC and National Weather Service, including high risk days and locations considered "critical burn environments."

Working to Minimize the Shutoffs

To help speed inspections and repairs, the company has requested mutual aid of 1,000 workers from other energy companies, including ATCO Energy in Alberta, Xcel Energy in Minnesota and Florida Power & Light. These crews are expected to be staged and briefed on the restoration plan by Sunday evening. If weather progresses as expected, restoration could begin in some portions of the affected area as early as Monday afternoon.

The company and its mutual aid partners will prioritize areas that can be safety restored to bring the maximum number of customers back online as quickly as possible.

PG&E is also working to minimize customer impact wherever possible through a combination of sectionalizing the grid and providing emergency backup power generation resources that will be able to quickly re-energize customers in portions of some cities.

How Customers Can Prepare

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

  • Update their contact information 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 Public Safety Power Shutoff.
  • 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 numbers.
  • Build or restock your emergency kit with flashlights, fresh batteries, first aid supplies and cash.
  • Keep in mind family members who are elderly, younger children and pets.
  • Learn more about wildfire risk and what to do before, during and after an emergency to keep your family safe at PG&E's Safety Action Center.

To support customers in the affected areas, PG&E will open Community Resource Centers which provide restrooms, bottled water, electronic device charging and air-conditioned seating. Mobile resource stations (vans), when available, will provide bottled water, phone-charging and latest information for customers. PG&E is working with counties and cities on locations and will provide the list including operating hours prior to initiating the PSPS.
