Indiana Governor Eric J. Holcomb announced plans to bring a more than $3 billion electric vehicle (EV) battery cell plant to St. Joseph County, creating 1,700 manufacturing jobs. The new battery cell plant, a joint venture between Michigan-based General Motors and Korea-based Samsung SDI, is scheduled to begin operations in 2026.  

GM and Samsung SDI, which announced their joint venture in April, will build the plant just east of New Carlisle at Larrison Boulevard and Indiana 2 to supply GM’s EV production needs. GM plans to install more than 1 million units of annual EV capacity in North America in 2025 and accelerate from there.

The new facility will house production lines to build nickel-rich prismatic and cylindrical cells and is expected to help increase the accessibility and affordability of EVs. Once complete, the plant will have more than 30 GWh of capacity.

GM, which already has five facilities across the state, recently announced plans to invest $632 million in its Fort Wayne Assembly to expand operations and upgrade equipment to support its growing full-size truck business. GM also announced plans to invest $491 million to expand and upgrade its Marion, Indiana, facility to support EV production.      

Construction is planned to begin within the next year with the companies planning to start production in New Carlisle in 2026.

The Indiana Economic Development Corporation is working with GM and Samsung SDI to finalize a performance-based incentive offer to support the joint venture’s investment and job creation plans. St. Joseph County, Indiana Michigan Power, and Northern Indiana Public Service Company offered additional incentives.
