American automotive and technology company Rivian (NASDAQ: RIVN) and critical materials and energy technology company Redwood Materials today announced a partnership to deploy pioneering battery energy storage at Rivian's Normal, Illinois manufacturing facility. Using more than 100 second-life Rivian battery packs, Redwood and Rivian's solution will initially provide 10 megawatt-hours (MWh) of dispatchable energy to reduce cost and grid load during peak demand periods—saving on cost and supporting grid security and reliability.

Rivian will provide EV battery packs to Redwood, who will integrate them into a Redwood Energy system, supported by the company's Redwood Pack Manager technology, allowing their stored energy to be used on-site by Rivian's plant in Normal. This system is rapidly scalable and offers significant cost benefits by using safe and proven EV batteries. This approach enables faster, more flexible deployment of energy capacity directly at high-demand sites like manufacturing facilities.
