Samsung SDI Takes Full Ownership of the New Carlisle Indiana Battery Plant

Impact

This isn't an isolated GM retreat: GM exited a nearly identical LG Energy Solution joint venture near Lansing, Michigan in 2025, meaning both Samsung SDI and LGES now independently run former GM-anchored Midwest gigafactories, and a three-way sprint with SK On is underway to grab the fast-growing U.S. energy storage (ESS) market. Full ownership also lets Samsung SDI re-spec the line from the originally planned 27 GWh of EV-grade NCA cells toward ESS-grade LFP chemistry without a GM vote, and the timeline suggests the company locked in over $2.35 billion in U.S. ESS supply contracts in December 2025 and March 2026, months before the buyout, meaning the ESS pivot may have been the precondition for the deal, not the result of it. The plant also sits in Olive Township alongside AWS's $13.8 billion, 2.25-gigawatt Project Rainier data center campus, a natural ESS anchor customer county officials haven't publicly confirmed a supply relationship with.

For the huddle

If Samsung SDI's Olive Township plant pivots toward ESS batteries for data centers like AWS's neighboring Project Rainier campus, is there a supply or service opportunity for us in that corridor before the contracts get locked in elsewhere?

Samsung SDI has already signed over $2.35 billion in U.S. storage supply contracts and sits next to AWS's $13.8 billion Project Rainier campus, so the window to position as a local supplier or service provider is open now, before a confirmed customer relationship narrows it.
