Rather than rebuilding poles and wires over increasingly dry hillsides, which could raise the risk of equipment igniting catastrophic fires, the nation’s largest utility decided to give Briceburg a self-reliant power system. The stand-alone grid made of solar panels, batteries and a backup generator began operating this month. It's the first of potentially hundreds of its kind as Pacific Gas & Electric works to prevent another deadly fire like the one that forced it to file for bankruptcy in 2019.
