Energy storage company ESS announced it won a contract to supply three of its Energy Warehouse (EW) storage systems to Californian wineries. They will be installed in a solar and storage microgrid at Roederer Estate, Scharffenberger Cellars and Domaine Anderson, all in Mendocino County.
The systems will be delivered to Coldwell Solar, a developer and builder of renewable energy projects, and will be installed as a microgrid and made operational by late 2023. The three units will be deployed to three separate sites, each a standard 75 kW/500 kWh Energy Warehouse.
The company’s battery modules have been certified to the UL 9540A and UL 1973 standards. They are based on iron flow technology and provide up to 12 hours’ flexible energy capacity.
Financial details were not disclosed.
Sean Hood, COO of Coldwell Solar, said: “The wineries needed an energy storage solution that could withstand the elements and operate safely in a wildfire-prone region. With its inherent safety and low carbon footprint, ESS technology was the only option that meets the energy resilience and sustainability needs of our customer.”
The energy storage solution will safeguard the wineries against the impacts of Public Safety Power Shutoff events and other grid interruptions.
