Last week, SMUD took a decisive step toward its clean energy goal when it signed a contract with iron flow battery company ESS to deliver 200 megawatts/2 gigawatt-hours of its products, which store electricity in a liquid electrolyte containing dissolved iron.
ESS and the Sacramento Municipal Utility District announced that ESS would supply SMUD with flow batteries with a total capacity of 200 MW/2 GWh beginning next year.
This summer California experienced several flex alert days and the threat of rolling blackouts when power supplies dipped dangerously low. Now SMUD plans on installing large banks of batteries that can help provide more power during peak demand.
ESS completed the installation of a microgrid project including an ESS Energy Warehouse™ system at an industrial recycling facility in West Grove, Pennsylvania. The project was developed by TerraSol Energies, Inc., a developer and operator of turnkey solar and storage solutions for commercial customers.
Lithium-ion technology is currently used for most energy storage applications but as demand for batteries grows, challenges to adequate and reliable supply of this technology are emerging.
ESS has completed a microgrid installation at Sycamore International, a technology recycling company in West Grove, Pennsylvania. The new microgrid, which was developed by TerraSol Energies includes a 115-kW direct current solar array and an ESS Energy Warehouse, which is a long-duration iron flow battery system.
For Alan Greenshields, European Director of ESS Inc., renewables and long duration storage provide a lens through which one can spot opportunity in the face of such straits.
Enough stored renewable energy would reduce or eliminate the need for peak fossil fuel plants or, even worse, rotating power outages.
