Supplies will begin with NCA and later expand to LFP batteries produced at the StarPlus Energy plant in Indiana
SAMSUNG SDI continues to land mega-size deals in the U.S., accelerating ESS biz expansion
Company says its technology and safety have once again been recognized, reinforcing its position as North America’s sole non-Chinese supplier of prismatic ESS batteries
SAMSUNG SDI today announced the South Korean battery maker has landed another mega-size deal for ESS battery supplies in the United States, accelerating expansion into the global ESS market.
The company said its Michigan-based subsidiary SAMSUNG SDI America recently clinched a KRW 1.5 trillion ($1 billion) worth deal to supply ESS batteries in phases for a U.S. energy company over a four-year period from this year through 2029.
The batteries will be produced at StarPlus Energy’s plant in Indiana, a joint venture between SAMSUNG SDI and automaker Stellantis.
Initial supplies will begin with NCA (Nickel·Cobalt·Aluminum), and later expand to LFP (lithium iron phosphate).

The latest deal means that SAMSUNG SDI has been highly recognized for technological competitiveness of NCA and LFP batteries in the global market.
SAMSUNG SDI is currently increasing its presence in the U.S. market where demand for ESS is surging in line with the expanding renewable energy and artificial intelligence markets.
Last December, the Korean battery maker signed over KWR 2 trillion worth LFP ESS cell supply with a U.S. energy infrastructure company. The company is further strengthening its foothold in the U.S. market by snatching the latest deal.
SAMSUNG SDI is currently in talks with multiple global customers to provide batteries, with expectations to produce tangible outcomes in the near future.
Industry observers assess the series of mega-deals won by SAMSUNG SDI, backed by its prismatic battery technology(PrismStack) known for superior safety, to be a competitive edge for the company to win the ongoing Korean government-led bid for ESS battery supplies for state-run power companies.
SAMSUNG SDI’s prismatic batteries are already recognized by multiple U.S. energy businesses not only for their durability advantages over pouch-type batteries but also for fire-safety technologies and proven reliability, underscoring the company’s position as the only non-Chinese supplier of prismatic ESS batteries in North America.
"The latest series of orders confirm SAMSUNG SDI’s technological competitiveness and credibility in the global ESS market,” said a company official. “The company will continue its efforts to meet diverse needs for specific performances from global customers.”
