Common Questions
A Public Safety Power Shutoff is when PG&E proactively cuts power during high fire-risk conditions. Napa, Sonoma, and Marin counties are among the most frequently affected areas in California. A well-maintained generator with a full fuel tank is the only way to keep your business running during a multi-day PSPS event.
We recommend a full service and load bank test before fire season begins in late summer. This includes checking air filtration for smoke and ash ingestion, verifying fuel levels, testing the automatic transfer switch, and confirming remote monitoring is operational. Wineries with barrel storage and temperature-controlled caves cannot afford power gaps during harvest.
Yes. We service generators at rural properties, remote resorts, and agricultural operations throughout western Sonoma, the Sonoma Coast, and West Marin. These locations often have the longest utility restoration times during storms, making reliable backup power even more critical.
We focus on service, maintenance, and repair rather than new installations. However, we can assess your facility's power requirements, recommend the right generator size, and refer you to trusted installation contractors in Napa, Sonoma, and Marin. Once installed, we handle all ongoing maintenance and testing.
Diesel fuel degrades over time, especially in Wine Country where generators may sit idle for months between outages. We recommend fuel testing annually and fuel polishing every 2 to 3 years, or sooner if testing shows microbial contamination or excessive water content. Clean fuel is the difference between a generator that starts and one that doesn't.
