On-site energy developer details regional microgrid deployments at Grgich Hills Estate, offering vintners an economically sound path to energy independence and demand charge control
July 20, 2026 (Napa Valley, CA) — Sprocket Power, a leading developer of commercial on-site energy infrastructure, today formally announced its strategic expansion into the commercial viticulture segment, revealing an active pipeline of regional microgrid projects engineered to deliver long-term operational resilience across California’s premier wine-growing corridors. The announcement was made in conjunction with the company’s featured presentation at Napa Green’s “Energy Solutions and Independence for Wineries” summit, held earlier today at Grgich Hills Estate in Rutherford.
For premium West Coast vintners, environmental sustainability benchmarks and bottom-line operational survival have become deeply codependent. Confronted by escalating utility rates and recurring Public Safety Power Shutoffs (PSPS), regional vineyard operators are actively moving toward self-contained, load-bearing energy infrastructure to secure absolute production continuity.
At today’s interactive workshop, Sprocket Power executives joined technical collaborators from Schneider Electric, VinWizard, and MCE to break down the real-world operational data behind localized microgrids. By seamlessly integrating on-site solar generation, industrial battery storage, and dynamic real-time energy management software, these bespoke systems enable wineries to insulate themselves from utility volatility, mitigate crushing demand charges, and protect premium yields during volatile weather seasons.
“Our formal entry into the Napa and Sonoma agricultural sectors is focused entirely on proving that long-term sustainability and predictable operational economics can go hand in hand,” said Maria Fields, CEO of Sprocket Power. “By using tailored on-site generation and smart battery assets to systematically manage peak demand, we are helping vintners build a definitive, economically sound path away from grid dependence, drawing on concrete data from active regional projects rather than theory.”
The commercial rollout highlights key case studies from Sprocket Power’s expanding regional pipeline, featuring:
The presentation featured first-hand operational commentary from Vance Rose of Harper’s Rest and Gita Mallya of Domaine Carneros, detailing how site-specific energy portfolios successfully align with rigid corporate sustainability standards while delivering measurable cost reductions.
