Samsung SDI announced on January 1, 2026, that its Michigan-based subsidiary, Samsung SDI America, signed a 1 GWh agreement to supply energy storage systems to Alpha Omega Power, a U.S. utility-scale battery storage developer and independent power producer. Including an initial contract signed late last year, the two agreements total 1.5 GWh.
Under the latest agreement, Samsung SDI will supply its Samsung Battery Box (SBB) 1.7, an integrated energy storage system using nickel cobalt aluminum batteries. The cells and modules will be manufactured at the StarPlus Energy plant in Kokomo, Indiana, and delivered by the end of this year.
Alpha Omega Power plans to deploy the systems in large-scale projects intended to support grid reliability and growing power demand. Construction is scheduled to begin next year in the Western Electricity Coordinating Council and Electric Reliability Council of Texas power markets.
According to Samsung SDI, the SBB 1.7 uses high-capacity, high-nickel NCA chemistry and provides 17% higher energy density than the previous SBB 1.5 while retaining the same 20-foot footprint. The system also uses AI-powered algorithms for early anomaly detection and battery life prediction and is designed for 25 years of continuous operation.
The SBB 1.7 has obtained certifications and met safety standards including NFPA 855 for stationary energy storage installations and UL 9540 for energy storage systems. It also incorporates Samsung SDI’s Enhanced Direct Injection technology, which injects fire-extinguishing agents directly into individual battery modules.
Samsung SDI said it has secured several ESS supply agreements with U.S. energy companies this year and is discussing additional contracts with local customers. The latest agreement expands its North American energy storage business while supporting Alpha Omega Power’s utility-scale storage portfolio.
