ESS iron-flow storage to be used in California winery microgrid

Long-duration energy storage provider ESS will deliver three Energy Warehouse systems to Coldwell Solar for a solar + storage microgrid at Roederer Estate, Scharffenberger Cellars and Domaine Anderson — California wineries in Mendocino County known for their sparkling and still wines. Coldwell Solar worked with the wineries to design a system that met their needs and the microgrid is expected to be operational in late 2023.

“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. We look forward to partnering with ESS on future projects to accelerate clean energy deployments in the state,” said Sean Hood, COO of Coldwell Solar.

“Our safe and sustainable long-duration energy storage systems are ideally suited to a wide variety of commercial and industrial applications. We’re pleased to support these wineries’ commitment to sustainability while providing the energy security needed to continue delivering economic benefits to the Mendocino region,” said Hugh McDermott, SVP of business development for ESS.

ESS iron-flow technology provides long-duration energy storage and is ideal for applications that require up to 12 hours of flexible energy capacity. ESS technology is safe, non-toxic and has a 25-year design life without capacity fade.
