SAMSUNG SDI today announced that its U.S. subsidiary, SAMSUNG SDI America (SDIA), has signed an agreement with Jupiter Power, the premier U.S. integrated developer, owner and operator of utility-scale battery energy storage systems (BESS), to supply LFP (lithium iron phosphate) batteries in a deal estimated to be worth several trillion KRW.

Under the agreement, SAMSUNG SDI will supply a total of 16 GWh of LFP batteries over three years starting in 2029 for Jupiter Power’s large-scale ESS projects in the U.S. Including the previous deal, SAMSUNG SDI’s total orders from Jupiter Power now amount to approximately 27GWh.
Jupiter Power, backed by Global Infrastructure Partners (GIP), a part of BlackRock, has 19,700 MWh of projects (operating, in construction or committed, and another 110,000 MWh in development across the United States.
The LFP batteries for Jupiter Power will be produced in Indiana.
By securing the large-scale order shortly after commencing mass production of LFP batteries at the plant, SAMSUNG SDI has demonstrated the global competitiveness of its LFP battery technology while accelerating its expansion in the BESS market.
As the only non-Chinese producer of prismatic batteries for BESS applications in North America, SAMSUNG SDI has also secured non-Chinese sources for key battery materials, further strengthening trust among U.S. energy companies.
SAMSUNG SDI has recently secured a series of orders as it expands its BESS portfolio to include LFP batteries in addition to NCA-based batteries. To support its expanding LFP business, the company is also strengthening its supply chain through material supply agreements with Korean companies, including POSCO Future M and L&F.
“This agreement reflects the competitiveness and supply capabilities of our locally produced prismatic LFP batteries in the U.S.,” said Fabrice Hudry, President ESS of SDIA. “Building on our differentiated prismatic battery technology and stable supply chain, we will continue to expand our presence in the global BESS market.”
“Securing reliable, domestically manufactured equipment is central to how Jupiter Power plans and de-risks our build program,” said Andy Bowman, Chief Executive Officer of Jupiter Power. “SAMSUNG SDI’s LFP batteries, produced here in the U.S., strengthen our supply chain as we continue to deliver reliable power and capacity when and where the grid needs it most.”
