Domaine Carneros Winery in Napa Valley has partnered with Schneider Electric to implement a cutting-edge microgrid system, enhancing energy security, sustainability, and operational efficiency.
Microgrid Project Overview
The microgrid integrates 614 solar panels, a 250-kVA battery storage system, and a backup generator, collectively producing 740 MWh of electricity per year. This setup allows the winery to self-generate 70% to 80% of its energy needs, reducing reliance on the main grid and ensuring uninterrupted operations during Northern California’s frequent power outages and wildfire-induced shutdowns.
Key features of this microgrid include:
- Island Mode Capability: Enables the winery to disconnect from the main grid and operate autonomously during outages.
- Energy Storage Optimization: The battery system balances supply and demand, reducing peak-time energy costs.
- Decarbonization Efforts: Supports California’s clean energy goals by integrating renewable energy sources.
Industry Implications
California’s wine country has faced recurring power disruptions due to wildfires and Public Safety Power Shutoffs (PSPS) by utilities. Wineries and agricultural facilities are increasingly considering microgrids as a long-term solution to maintain operations and protect valuable inventory.
Industry-wide benefits include:
- Resilience Against Grid Failures: Provides energy reliability during wildfire-related power shutoffs.
- Cost Savings Over Time: Reduces dependence on expensive peak-hour electricity from the grid.
- Sustainability Compliance: Helps vineyards meet California’s carbon reduction targets.
Looking Ahead
The Domaine Carneros microgrid serves as a scalable model that can be replicated in agricultural, commercial, and industrial applications. It demonstrates how distributed energy resources (DERs), battery storage, and smart control systems enhance resilience and efficiency.
With climate-related risks increasing, microgrids are becoming an essential component of business continuity planning. This project sets a precedent for other wineries and businesses looking to integrate microgrid technology for operational stability and sustainability.
The Microgrid Systems Certificate Program, developed by Telepath Systems in conjunction with Cleveland State University, provides specialized training in microgrid architecture, operational strategies, and system modeling. This program equips engineers and energy professionals with the skills needed to contribute to projects like those being planned for Domaine Carneros.
