Domaine Carneros, a renowned sparkling wine producer in Napa Valley, blends centuries-old French winemaking traditions with pioneering energy innovation. Founded by the family behind Champagne Taittinger, the winery relies on the méthode champenoise, a labor-intensive process requiring precision and continuous power. Facing challenges from California’s increasingly frequent wildfires and grid disruptions, Domaine Carneros implemented a comprehensive microgrid solution in partnership with Schneider Electric’s EcoStruxure™ platform.
At the heart of this system is an Energy Control Center-based microgrid, integrating solar power, battery storage, and backup generation. Supported by EcoStruxure Microgrid Advisor and Microgrid Operation, the solution ensures seamless power transitions, optimized energy use, and uninterrupted operations. The results include 740 MWh of annual solar generation—the equivalent of removing 110 cars from the road—alongside a 70% reduction in generator fuel use during outages.
This innovative approach allows Domaine Carneros to maintain the strict environmental conditions needed for sparkling wine production while advancing its sustainability goals. By demonstrating how resilient power can protect tradition, the winery sets a model for the broader wine industry—proving that operational reliability, energy efficiency, and environmental stewardship can coexist to create lasting impact.
