Domaine Carnero Deploys Microgrid

Domaine Carneros, a winery in the Napa Valley region in California, announced it reduced its carbon emissions last year by 375 metric tons of CO2 through the deployment of a microgrid.

A newly implemented Schneider Electric microgrid helped the winery save over $70,000 on annual energy costs and now generates 70% to 80% of its energy.

The deployment of the microgrid doubled Domaine Carneros’ energy generation capacity over the solar system that the winery originally installed 20 years ago. Excess solar energy is stored in the on-site battery for use at night or during a power outage, and a backup generator is available to provide additional energy when solar power isn’t available.

“Our ability to craft the highest quality wines and create the most memorable wine experiences is dependent on a reliable and efficient source of energy,” said Remi Cohen, CEO of Domaine Carneros, in a statement. “With Schneider Electric’s advanced microgrid technology, we’ve been able to revolutionize our energy infrastructure and maximize our renewable energy use. At a time when power outages are becoming more common, due to wildfires and severe weather, this has been critical to keeping our operations online.”

The microgrid enables Domaine Carneros to have complete self-sufficiency during power outages. It allows the winery to connect and disconnect from the grid and operate in “island mode,” with a battery storing energy for use as needed. If the power grid goes down or electricity prices peak, the microgrid responds, providing a continuous supply of power during disruptions to the grid and helping avoid excess electricity demand charges during peak hours.

Using data points such as energy production and energy demand, the microgrid’s intelligent controls software utilizes AI to apply utility tariff models, time-of-use rates, and demand charges for the benefit of the winery in real time.

Domaine Carneros also offers four solar-powered electric car charging stations for guests.

Schneider Electric partnered with PowerFlex, a division of EDF Renewables, to design the microgrid. PowerFlex provided the electrical infrastructure to integrate the solar power and battery storage system.
