PSPS UPDATE: PG&E Has Shut Off Power for Safety During Dry Northerly Wind Event, Affecting About 8,400 Customers in Small Portions of Eight Counties

Safety Shutoffs Began Wednesday, August 30 at 2:00 a.m. PT

Weather All Clears Anticipated in the Afternoon Wednesday, August 30, Allowing Power Restoration to Begin

OAKLAND, Calif. — Pacific Gas and Electric Company (PG&E) confirms that it is in the process of implementing a Public Safety Power Shutoff (PSPS) affecting about 8,400 customers in two tribal areas and small portions of eight counties. The first wave of targeted safety shutoffs began Wednesday, August 30 around 2:00 a.m. Pacific Time with the last wave of targeted safety shutoffs expected to be completed around 5:30 a.m. PT.  According to PG&E meteorologists, the primary period of concern is early Wednesday morning, where wind gusts up to 45 mph are expected to spread southward down the western Sacramento Valley and adjacent terrain. Relative humidity values may fall to 10%-20% in the Sacramento Valley. This has prompted the National Weather Service to issue a Red Flag Warning for the greater Sacramento Valley with the highest threat mainly along and west of Interstate 5.  As a result of this wind event, combined with low humidity and extremely dry vegetation, PG&E began notifying customers – via text, email, and automated phone call—on Monday, August 28 approximately two days prior to the potential shutoffs. PG&E then sent one-day advance notifications on Tuesday, August 29 to customers in areas where PG&E anticipated needing to proactively turn off power for safety to reduce the risk of wildfire from energized power lines. PG&E also contacted customers, as well as agencies, tribes, and counties, in the hours prior to the de-energization process.

  • Tehama County: 3,249 customers, 352 Medical Baseline customers 
  • Yolo County: 30 customers, 1 Medical Baseline customer 

Restoration is Expected to Begin later on Wednesday, August 30  PG&E anticipates notifying customers on Wednesday afternoon when the weather system has passed and will provide continuous updates on when to expect the power to turn back on. Once conditions are clear, PG&E electric crews will begin patrolling and checking de-energized lines for hazards or damage to make sure it is safe to restore power. Restoration steps include: 

  • Inspect: PG&E crews will work to visually inspect for potential weather-related damage to the lines, poles, and towers. 
  • Repair: Where equipment damage is found, PG&E crews work to isolate the damaged area from the rest of the system so other parts of the system can be restored. 
  • Restore: Once the poles, towers, and lines are safe to energize, PG&E’s Control Center can complete the process and restore power to affected areas. 
  • Notification: Customers are notified that power has been restored. 

How Customers Can Prepare

  • Use a cell phone or hard-wired phone. Cordless phones do not work without electricity. 
  • Use battery-operated flashlights, not candles, which may pose a fire hazard. 
  • Unplug or turn off all electric and heat-producing appliances (e.g., air conditioners, washers and dryers, ovens, stoves, irons) to avoid overloading circuits. Overloaded circuits can be a fire hazard once power is restored. 
  • Unplug televisions and computers that were in use when the power went out. 
  • Leave a single lamp on to alert you when power returns. 
  • Keep refrigerator and freezer doors closed, and place extra containers of ice inside to preserve food. A full freezer will remain colder longer. 
  • Notify your alarm company if you have an alarm system. Equipment can be affected by outages. 
  • Turn your appliances back on one at a time when conditions return to normal. 
  • Reset clocks, thermostats, and other programmed equipment after power is restored. 

Generator Safety  Backup power can be a vital part of any emergency preparedness plan in the event of a power outage. PG&E’s residential and business customers can review key considerations, safety tips, financing, and retailer information by visiting  Customer Support  On Wednesday, eight Community Resource Centers (CRCs) in five counties will open to support customers affected by this event. View the most current list of CRCs at CRCs open at 8 a.m. and close at 10 p.m. for the remainder of the shutoff.  During a PSPS, PG&E opens CRCs where community members can access resources, including:  

  • A safe location to meet their basic power needs, such as charging medical equipment and electronic devices.  
  • Up-to-date information about the PSPS. 
  • Water, snacks, and other essential items to reduce hardships to our customers. 

Why PG&E Calls a PSPS Event  The sole purpose of a PSPS is to reduce the risk of major wildfires during severe weather. While a PSPS is an important wildfire safety tool, PG&E understands that losing power disrupts lives.  We initiate a PSPS event 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 19 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 was declared by the National Weather Service  
  • Real-time observations from our network of more than 1,500 weather stations.  

Our decision-making process also accounts for the presence of trees tall enough to strike powerlines.  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 that may lead to further analysis from our meteorology team to determine if a PSPS event is necessary.  Here’s Where to Learn More

PG&E’s Commitment to Wildfire Safety  Using advanced technologies and rebuilding the electric system from the underground up, we are preventing wildfires, improving reliability, and reducing costs over the long term. We are building the energy grid of the future that our customers deserve while also taking immediate steps to keep customers safe.  Our wildfire prevention work relies on layers of protection to make our system safer and more resilient while positioning us to better serve our customers in the short and long term. These tools help us respond to our state’s evolving climate challenges:   

  • Our 10,000-mile Undergrounding Program is the largest effort in the U.S. to underground powerlines as a wildfire risk reduction measure.  
  • In addition to undergrounding, we are strengthening the electric system with stronger poles and covered powerlines in and near high fire-risk areas. 
  • Enhanced Powerline Safety Settings (EPSS) decrease ignitions and provide wildfire protection to all customers living in high fire-risk areas.  
  • We continue to reduce the impact of Public Safety Power Shutoffs (PSPS). While there were no weather-driven PSPS outages in 2022, it continues to be a top focus for our team. 
  • We are managing trees and other vegetation located near powerlines that could cause a power outage and/or ignition. 
  • We are also investing in advanced tools and technologies like artificial intelligence and drones that help us automate fire detection and response.
