Wine Industry Advisor recently covered Sprocket Power’s expansion into the commercial viticulture segment, following our presentation at Napa Green’s “Energy Solutions and Independence for Wineries” summit at Grgich Hills Estate in Rutherford.
For Napa and Sonoma vintners, rising utility rates and recurring Public Safety Power Shutoffs (PSPS) have turned energy from a line item into a production risk.
When refrigeration, chilling, and bottling operations depend on uninterrupted power, an outage doesn’t just cost money; it can cost a vintage.
That’s the gap our on-site energy systems are built to close.
By combining solar generation, battery storage, and active energy management, we help wineries manage demand charges and maintain power through grid events — with a system sized and modeled against each site’s actual operating profile, not a generic install.
The feature highlights two projects from our growing regional pipeline:
- Domaine Carneros — an active case study in on-site generation supporting day-to-day operations.
- Harper’s Rest Winery (Sonoma’s Russian River Valley) — an upcoming microgrid engineered to protect from grid failure. Learn more about their background story here and see our case study for Harper’s Rest here.
As Sprocket Power CEO Maria Fields told Wine Industry Advisor, the goal is proving that “long-term sustainability and predictable operational economics can go hand in hand” for California vintners.
