Rivian and Redwood Materials 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 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. Stationary energy storage technologies play a key role in reducing cost and increasing stability both for the customer and the grid at large.

During periods of peak demand like heat waves, Rivian can instantly deploy energy stored in its second-life batteries to offset increased strain on the grid, avoiding having to purchase more expensive electricity while also avoiding additional load on the power system. Redwood's deep expertise in battery systems and power integration positions the company to capture a massive domestic supply of energy storage that is already accumulating. By transitioning these packs into stationary assets before recycling them, we can extend their useful life, decrease reliance on imported energy storage, and defer billions of dollars in costly infrastructure upgrades.
