GM Closes Detroit Battery Plant Over Lease, Not EVs
Original: GM to close Detroit battery-assembly plant, but not for reasons you might think
Why This Matters
Battery plant closures signal how EV supply chains are restructuring post-federal-incentive repeal.
GM confirmed it will close the Brownstown Battery Assembly Plant near Detroit. The site built battery packs for the Cadillac Celestiq and Chevrolet Corvette E-Ray. Closure is lease-driven; workers and work will move to other GM facilities.
General Motors is shutting down its Brownstown Battery Assembly Plant south of Detroit, but the company is quick to distance the decision from any EV retreat. A GM spokesperson confirmed to TechCrunch that the closure is lease-driven — the site agreement was nearing its end — not a strategic pullback from electrification.
The Brownstown facility assembled battery packs for the Cadillac Celestiq, GM's flagship luxury EV, as well as electric drive units and battery packs for the Chevrolet Corvette E-Ray plug-in hybrid. Automotive News first reported the closure. GM said employees and production work will transfer to other facilities, though it declined to name them.
Context matters here. GM's EV ambitions have been operating under real pressure since the One Big Beautiful Bill Act — signed last year — repealed federal incentives for EV production and sales. The automaker has grown quieter about electrification publicly, but hasn't abandoned it. GM still produces the Chevrolet Silverado EV and the limited-run Chevrolet Bolt, and is actively researching lithium-manganese-rich and sodium-ion battery chemistries. A new $900 million facility is also in the pipeline to accelerate commercialization of next-generation battery tech.
