TLDRs;
- Samsung SDI lands approximately $1 billion U.S. contract for prismatic ESS batteries with deliveries extending to 2029.
- Supply strategy begins with nickel-cobalt-aluminum technology before transitioning to lithium iron phosphate batteries.
- Joint venture StarPlus Energy in Indiana serves as production hub for U.S. market penetration.
- Federal incentives from Inflation Reduction Act bolster Samsung’s domestic manufacturing approach.
South Korean battery manufacturer Samsung SDI reported a modest decline in shares (OL2T.L) even after revealing a substantial $1 billion agreement to deliver prismatic batteries for energy storage systems (ESS) across the United States. The contract, worth around 1.5 trillion won, marks a delivery schedule starting this year and extending through 2029, underscoring the company’s commitment to penetrating North America’s expanding energy storage sector.
Billion-Dollar Agreement Signals American Market Push
The arrangement calls for Samsung SDI to deliver nickel-cobalt-aluminum (NCA) batteries in the initial phase, followed by lithium iron phosphate (LFP) technology in subsequent stages. Production will take place at StarPlus Energy’s Indiana facility, a collaborative venture between Samsung SDI and Stellantis.
This collaboration draws on Stellantis’ established capabilities in electric vehicle battery manufacturing, establishing a supply channel that serves both automotive electrification and stationary energy storage needs.
Indiana Joint Venture Powers Manufacturing Strategy
Located in Indiana, StarPlus Energy forms the backbone of Samsung’s American expansion plans. The manufacturing site is part of a larger $5.7 billion capital commitment and has secured $7.54 billion in federal financing directed toward EV battery manufacturing capabilities.
Multiple production lines originally intended for EV battery manufacturing are being reconfigured for ESS battery output, mirroring an industry-wide trend toward grid-scale storage solutions. The American production base establishes Samsung SDI as the sole non-Chinese provider of prismatic ESS batteries in the North American market, offering strategic value in a region prioritizing supply chain diversification.
Federal Legislation Shapes Investment Climate
Legislative support from Washington plays a crucial role in enabling this growth trajectory. The Inflation Reduction Act provides substantial financial incentives for domestically manufactured battery products, including $35 per kilowatt-hour (kWh) for battery cells and $10 per kWh for complete modules.
Research from Benchmark Mineral Intelligence indicates that projected U.S. battery manufacturing capacity has grown approximately two-thirds since the legislation took effect. Samsung’s contract and facility development strategy directly capitalizes on these incentives, establishing the company as a viable substitute for Chinese battery suppliers.
Local Supply Networks and Market Dynamics
Beyond financial incentives, the agreement mirrors wider patterns in domestic manufacturing ecosystem development. Complementary suppliers like Hanjung America are establishing Indiana-based operations to deliver thermal management and fire suppression systems for battery manufacturing processes.
The focus on American-based production responds to both regulatory requirements and escalating ESS market demand, fueled by renewable energy deployment and the growing power consumption associated with artificial intelligence computing infrastructure.

Notwithstanding these strategic developments, Samsung’s OL2T.L shares experienced a slight downturn, indicating measured investor response to competitive pressures in the global battery marketplace and the timeline required for capital investments to generate returns. Market observers acknowledge that while the agreement demonstrates promising long-term prospects, immediate profitability for large-scale ESS initiatives remains influenced by volatile energy markets and manufacturing scaling schedules.
Samsung SDI’s billion-dollar contract represents a significant milestone in energy storage sector development. Through its combination of American manufacturing presence, joint venture capabilities, and legislative advantages, the organization is establishing itself as a major participant in North America’s transition toward sustainable, dependable energy infrastructure. Although investor reaction proved subdued, industry analysts view the agreement as strengthening Samsung’s strategic foundation in the ESS marketplace for years ahead.
