Pacific Gas & Electric Co. (PG&E) has begun construction on a microgrid in Arnold aimed at mitigating the impacts of Public Safety Power Shutoffs (PSPS).

The microgrid is “designed to provide electricity to certain customers and shared community resources using temporary generation during future PSPS events,” a PG&E press release reads.

The microgrid site in Arnold is located at Ebbetts Pass Fire District Station 1 at 1037 Blagen Road.

“PG&E will be able to rapidly connect mobile generators to the site, allowing the fire station, post office, gas stations, markets, a propane facility, hardware store, restaurants and other facilities and community services to remain energized during future PSPS events impacting the area,” the release reads. “The Arnold temporary microgrid energization zone includes PG&E customers in the general vicinity of Highway 4, extending between Pine Drive and Henry Street.”

The site in Arnold “was identified and selected through an extensive process involving the analysis of prior and expected future PSPS events, along with overall feasibility and other utility work in the region that could reduce PSPS impacts,” the release reads. “The plan for the Arnold temporary microgrid energization zone includes approximately 125 PG&E customers served by underground power lines to be safely energized during a PSPS event.”

Throughout its service area, PG&E already has six microgrid generation sites for use during PSPS events, and is currently developing an additional five sites.
