September 21 (Renewables Now) - Wilsonville Oregon-based ESS Inc (NYSE:GWH) on Tuesday unveiled an agreement to supply up to 200 MW/2 GWh of its long-duration iron flow batteries to community-owned utility the Sacramento Municipal Utility District (SMUD).
Under the multi-year agreement, ESS will be providing its Energy Warehouse and Energy Center products for integration with the SMUD grid from 2023. The agreement will advance SMUD’s 2030 Zero Carbon Plan.
As part of the deal, ESS plans to establish facilities for battery system assembly, operations and maintenance support and project delivery in Sacramento. Together with SMUD, the company also plans to create a Centre of Excellence to develop workforce for long-duration energy storage technology in collaboration with higher education institutions.
ESS’ iron flow technology has a 25-year lifespan. The company says that 200 MW/2 GWh of storage, when paired with renewable energy, equates to removing 284,000 tonnes of carbon dioxide (CO2) emissions per year. It will be able to power 60,000 homes for 10 hours.
