Pacific Gas and Electric Company (PG&E) said today that its Enhanced Powerline Safety Settings (EPSS) now protect approximately 3 million people, or more than 1 million customers, who live in high fire-risk areas within the company's service area. The safety settings turn off power within one-tenth of a second when a fault, such as a tree limb coming into contact with a powerline, is detected. Last year, on 170 circuits with safety settings enabled, there was an 80% reduction in CPUC-reportable ignitions in High Fire Threat Districts that could result in a wildfire, compared to the prior three-year average.
Based on EPSS's success in 2021 as a proven wildfire prevention technology, PG&E has expanded the program to more than 1,000 circuits encompassing more than 25,000 distribution line miles in high fire-risk areas this year as well as approximately 18,000 line miles in adjacent portions of the system. These circuits are generally in foothill areas and all are in high-fire threat areas.
