[DigitalToday reporter Dae-geon Seok (석대건)] Samsung SDI's Americas unit Samsung SDI America (SDIA) said on Sunday it has signed a battery supply contract for energy storage systems (ESS) with a major U.S. energy specialist. The deal is worth about 1.5 trillion won. Supplies will be delivered in stages over four years from this year through 2029.

The volume under the deal will be produced at Starplus Energy (SPE), the Samsung SDI-Stellantis joint venture plant in Indiana. It plans to supply NCA (nickel-cobalt-aluminium) and LFP (lithium iron phosphate) batteries in sequence.

Samsung SDI signed a contract worth more than 2 trillion won late last year to supply LFP batteries for ESS to a U.S. energy infrastructure developer and operator. Including the latest deal, it has secured a series of large orders in a short period, expanding its foothold in the U.S. market. The company cited rising ESS demand driven by expanded renewable energy development and growth in the AI industry as factors.

Samsung SDI also signed a large battery supply deal in the United States earlier this year. It is in talks with multiple global customers on additional supply contracts, and some are expected to deliver visible results soon.

Samsung SDI is currently the only non-Chinese prismatic ESS battery maker in North America. Prismatic batteries offer higher durability than pouch-type batteries. It is being assessed as having met the standards demanded by U.S. energy companies on the strength of its fire safety technology and reliability.

A Samsung SDI official said, "The recent string of orders is an opportunity to confirm our technology and reliability in the global ESS market." The official added, "We will continue to respond to diverse ESS demand in line with the project characteristics and performance requirements of global customers."
