In 2019, the Briceburg Fire burned over 5,000 acres in California’s Mariposa County. The fire damaged miles of PG&E’s power distribution lines, disrupting electrical service to the unincorporated community of Briceburg. Rather than rebuild the damaged power lines, PG&E is working with BoxPower to replace them with a solar + battery standalone power system.
The remote grid will support PG&E in its wildfire mitigation and energy resilience efforts in the face of escalating fire risk across the state. Set for completion in April 2021, the integrated solar, battery, and generator system will be the first operational remote grid for California’s largest investor-owned utility.
In addition to reducing wildfire risk, on-site power improves energy resilience. Briceburg’s residents will no longer be vulnerable to Public Safety Power Shutoff (PSPS) events. Additionally, the community will benefit from reduced carbon emissions since the solar with propane backup system supplies nearly 90 percent renewable energy.
The Briceburg project is one of the first remote grid installations PG&E is undertaking as part of its 2021 Wildfire Mitigation Plan, which the company submitted to the California Public Utilities Commission in February. The utility has identified the potential for several hundred eventual remote grid installations across the state.
Briceburg is an ideal test case for PG&E to explore renewable standalone power systems: a small community located at the end of a long set of distribution lines that once ran through forested terrain. The on-site power system will eliminate much of the line maintenance and vegetation management costs while also mitigating the risk of electrical-sparked fires.
