As part of its ongoing efforts to further reduce wildfire risks, Pacific Gas and Electric Company (PG&E) has implemented a number of new and enhanced wildfire mitigation tools to keep customers and communities safe.
Despite the impacts of COVID-19 on our entire society, PG&E has remained focused on executing important wildfire safety work as part of the company’s Community Wildfire Safety Program. Key milestones accomplished by the PG&E crews and contractors who continue to work in the field during this pandemic, while physical distancing, to keep their neighbors and communities safe include:
System Hardening: Installed stronger poles, covered lines and targeted undergrounding across 105 miles as part of a full-year plan for hardening 241 line miles.
Enhanced Vegetation Management: Inspected, pruned and removed vegetation that poses a higher potential for wildfire risk; completed 939 miles out of a planned 1,800 total miles.
More Weather Stations and Cameras: PG&E installed 116 advanced weather stations and 50 more high-definition cameras, with targets of 400 and 200 for the year, respectively.
Sectionalizing Devices: Separated the distribution grid into smaller sections for operational flexibility; 216 devices out of 592 targeted for the year are now operational.
Transmission Line Switches: Installed line switches to redirect power and keep communities energized. More than the 23 switches planned for this year have been installed.
Substation Temporary Generation: Created plans to locate temporary generation at up to 48 substations during a PSPS event to allow PG&E to safely energize thousands of customers and shrink the footprint of the PSPS event.
“Wildfire season is upon us, and the public can be assured of PG&E’s unwavering efforts to improve public safety and further reduce wildfire risk. The steps we are taking to keep our customers and communities safe are unprecedented and include everything from more robust vegetation management and hardening the grid to making our Public Safety Power Shutoff events smaller and shorter to making our website more resilient,” said Michael Lewis, senior vice president of Electric Operations for PG&E.
Here’s how PG&E is working to make PSPS events smaller in size, shorter in length and smarter for customers.
PG&E is upgrading its electric system to prevent wildfires and reduce the impact of future PSPS events on customers. The company’s efforts this year are expected to reduce the number of customers affected by a potential PSPS event by about one-third compared to a similar weather event last year. To make PSPS events smaller, PG&E is installing 592 sectionalizing devices capable of redirecting power and limiting the size of outages so fewer communities are without power, installing microgrids that use generators to keep the lights on for communities and conducting targeted undergrounding as part of system hardening.
PG&E is seeking to cut restoration times in half compared to 2019 so that power is restored to the majority of customers within 12 daylight hours after severe weather has passed. Steps the company is taking include: nearly doubling the exclusive-use helicopter fleet during events from 35 to 65, using two airplanes with infrared cameras capable of inspecting transmission lines at night. Also, mobilizing more field crews to speed up power-line inspections, investing in more reliable and innovative equipment, so PG&E field teams can inspect, repair and restore power quickly and utilizing mutual assistance from other utility companies to support PSPS restoration inspections when needed.
PG&E is working to provide better information and resources to customers and communities before, during and after a PSPS event, including delivering more assistance and outreach to help vulnerable customers.
This smarter approach will include: improving weather-monitoring technology, including installing new weather stations to more precisely predict the need for and timing of PSPS events, improving customer alerts with earlier estimates of restoration timing and upgrading Community Resource Centers (CRCs) so that customers without power have a place to go for device-charging and other basic needs. PG&E remains flexible with CRC deployment plans to adjust to the COVID-19 restrictions and best practices. Also, the utility will establish a new collaborative working approach with cities, counties, tribes and critical-service providers, bolster pge.com website capacity, partner with the California Foundation for Independent Living Centers and other community-based organizations to provide resources for vulnerable customers and conduct outreach, and expand in-language communications.

In advance of severe weather, PG&E encourages all customers to update their contact information at www.pge.com/mywildfirealerts and to make a plan to be ready for emergencies. More information including helpful tips can be found at www.safetyactioncenter.pge.com.
PG&E is also hosting a series of county webinars through August about the Community Wildfire Safety Program. For a full schedule of events and more information on PG&E wildfire prevention efforts, visit www.pge.com/wildfiresafety.
