GM to close Detroit battery assembly plant due to lease expiration
General Motors is closing its Brownstown Battery Assembly Plant, located south of Detroit. The facility produced battery packs for the Cadillac Celestiq and electric drive units as well as batteries for the Chevrolet Corvette E-Ray. GM confirmed that this closure is not related to its broader electrification strategy but rather due to an expiring lease on the site. Employees will be relocated to other GM facilities, though specific locations have not been disclosed. The decision comes amid a shift in U.S. policy affecting EV incentives after last year's One Big Beautiful Bill Act repealed key federal subsidies for electric vehicle production and sales. While GM has scaled back public statements about its electrification goals, it continues producing EVs like the Chevrolet Silverado EV and Bolt. The company is also investing heavily in battery research and development, including new chemistries such as lithium-manganese-rich and sodium-ion batteries.
