General Motors becomes first automaker to partner with Redwood across the full battery lifecycle

Today, we are announcing the latest chapter of Redwood’s partnership with General Motors: Redwood plans to deploy ~100 repurposed GM battery packs at one of GM’s operating plants in Michigan to provide 1.5 MW/7.2 MWh of dispatchable energy to the site. The installation is expected to save more than $3 million on local electricity bills at the plant over the lifetime of the installation – demonstrating how GM’s battery technology is flexing beyond EVs to help lower energy costs at manufacturing sites and support a more resilient energy future.  

This deployment makes General Motors the first automaker to engage Redwood across every stage of the battery lifecycle – recovering material from manufacturing scrap, recycling end-of-life GM EV packs, and now, deploying energy storage with GM EV packs in real-world energy infrastructure, including AI data centers and soon, an active manufacturing plant. Together, GM and Redwood are showing how repurposed EV batteries can keep working well beyond their useful life in a vehicle — first as energy storage, and ultimately as recovered material for future batteries.  

Through our existing partnership with Ultium Cells, GM's battery cell manufacturing joint venture with LG Energy Solution, Redwood already receives and recycles manufacturing scrap from their U.S. facilities. And when GM EVs reach the end of their useful life on the road, those packs come to Redwood—where they are either repurposed into energy storage systems or recycled to recover critical materials for new battery production. 

To date, Redwood has received over 28,000 metric tons (MT) of material from GM and Ultium Cells for recycling, with an additional ~10,000 EV packs now in the pipeline for repurposing through Redwood Energy. For GM, that creates a path to extend the value of its battery technology and battery materials, while also helping meet rising demand for reliable, dispatchable power. 

Repurposed GM EV packs are already at work. GM second-life batteries are contributing to Redwood's installation in Sparks, Nevada—the largest repurposed battery energy storage system in the world and the largest microgrid in North America, supporting AI infrastructure company Crusoe. As Redwood's supply of GM packs continues to grow, those batteries are being deployed across a broadening portfolio of energy storage projects nationwide. The Michigan deployment adds to that growing footprint and follows our recent deployment at Rivian's manufacturing facility in Normal, Illinois 

The U.S. already holds a massive and growing stockpile of domestic battery assets. The question is whether those batteries stay here as American energy infrastructure — powering factories, strengthening the grid, and keeping critical minerals in domestic supply chains — or whether that value leaves the country. With GM, Redwood is proving that the full battery lifecycle can be managed domestically, from the manufacturing line to the road to the grid, keeping American-made batteries at work in American industry.
