PG&E Implements Largest Planned Power Shutoffs in Eight Years Amid Escalating Fire Danger
By Drooid · · How we work
Core Event
Pacific Gas & Electric Co. (PG&E) activated a Public Safety Power Shutoff (PSPS) affecting roughly 90,000 customers across 29 California counties. By late afternoon, about 80,000 remained without power, with additional outages expected the next day.
Context: Red-Flag Weather and Wildfire Threats
The shutdown coincided with a Red Flag Warning from the National Weather Service for the North Bay interior mountains. Forecasters projected strong offshore winds, low humidity and temperatures in the high 90s °F, creating conditions conducive to rapid fire spread. The warning was expected to remain in effect through the following morning, with gusts up to 45 mph on western Sierra slopes and up to 60 mph in some valleys.
Scope and Impact
- Customer reach: Approximately 90,000 customers were notified; about 80,000 were without power at the peak.
- Geographic spread: Outages stretched from northern Lassen County to San Luis Obispo, concentrating in Sonoma, Napa, Lake, Mendocino and Solano counties.
- Critical services: Over 5,500 “Medical Baseline” customers and six tribal governments were on the impact list.
- Community resources: More than 40 resource centers were identified for charging devices, snacks, water and Wi-Fi.
Operational Responses and Resources
The shutdown disabled roughly 75 fire-monitoring cameras operated by ALERTCalifornia in Sonoma, Napa, Lake and Mendocino counties. A generator intended to keep the cameras online failed to start, causing a temporary loss of live feeds. PG&E spokesperson Megan McFarland confirmed the outage resulted directly from the power shutoff. Cal Fire’s Mendocino Unit remained fully operational, relying on field crews and other detection methods.
Local fire agencies responded to a concurrent 5-acre brush fire in Lake County, achieving 50 % containment by mid-afternoon and full containment by evening. Additional strike teams, hand crews and aircraft were staged for the heightened fire-weather scenario.
Official Statements & Responses
- PG&E described the PSPS as a “last-resort” measure to prevent lines or equipment from igniting wildfires.
- The El Dorado County Fire Protection District urged safe generator use, recommending placement at least 20 feet from any house opening.
- NWS meteorologists noted the red-flag conditions were driven by strong winds, low humidity and unusually warm temperatures for the season, projecting the warning would likely expire by late Friday as winds calm and humidity rises.
- Cal Fire spokesperson Sherri Wise said the agency can still operate effectively without the cameras, relying on community reports and on-ground observations.
Verbatim Quotes
- “When generators are being used, that they’re used at least 20 feet away from any opening in the house, to prevent carbon monoxide poisoning, and not to use any generators within the house or next to the house because of the fire danger that they could pose,” — Jacob Poganski
- “The cameras are a really great tool for us,” — Sherri Wise
What’s Next
The NWS forecast a cooling trend early the following week, with rain later that week expected to lower fire risk after the dry spell that began in early September. PG&E indicated the PSPS plan remains subject to change as weather evolves, and the utility will continue updating its outage map and resource-center listings.
