SEOUL \u2014 SK On, a leading global battery and trading company, announced today its major entry into the U.S. battery energy storage system (BESS) market with lithium iron phosphate (LFP) batteries, marking a significant milestone in the company\u2019s long-term growth and product diversification.<\/span><\/p>\n

SK On, part of South Korea\u2019s second largest conglomerate SK Group, secured a BESS supply contract with Flatiron Energy Development (\u201cFlatiron\u201d), a U.S. utility-scale energy storage developer, owner and operator. <\/span><\/p>\n

Under the agreement, SK On will be able to supply up to 7.2 gigawatt-hours (GWh) of BESS for Flatiron\u2019s projects in New England and other states through 2030. <\/span><\/p>\n

SK On will start with the supply of containerized BESS units featuring 1GWh of LFP batteries for a project in Massachusetts, with deliveries beginning in the second half of 2026. SK On will begin the mass production of LFP batteries for BESS by leveraging part of its electric vehicle (EV) battery production lines at SK Battery America (SKBA), its wholly-owned subsidiary in Commerce, Ga.<\/span><\/p>\n

This highlights SK On\u2019s strategic expansion into the BESS market in the United States alongside its growth in the LFP battery sector, underscoring its commitment to portfolio diversification and sustainable growth.<\/span><\/p>\n

Building on its partnership with Flatiron, SK On will continue delivering high-quality, American-made LFP batteries to support the nation\u2019s rapidly growing energy and BESS sectors. SK On has been strengthening its U.S. presence with a robust production network, with SKBA serving as its key hub since 2022. <\/span><\/p>\n

Known for its deep experience in manufacturing batteries for EVs, SK On plans to leverage cost-competitive and safe LFP batteries for BESS applications, where size and weight are less of a constraint. <\/span><\/p>\n

Its BESS will feature a modular design for flexible, scalable solutions, along with advanced safety measures such as heat propagation prevention and electrochemical impedance spectroscopy(EIS)-based battery diagnostics for reliable operation.<\/span><\/p>\n

Established in 2021, Flatiron specializes in utility-scale BESS development, managing the entire value chain from design to construction, and long-term operation across North America.<\/span><\/p>\n

\u201cHaving a partnership with a global leader in battery production with strong engineering, and integration capabilities, along with domestic resources has become a strategic imperative\u201d said Jonathan Poor, Chief Operating Officer and co-founder at Flatiron. \u201cWe look forward to deploying multiple projects under this partnership over the coming years.\u201d<\/span><\/p>\n

\u201cThis deal is significant as it expands both our product and business portfolio,\u201d said Daejin Choi, Head of ESS Business at SK On. \u201cWe will continue to strengthen our presence in the BESS sector by leveraging our advanced technologies and production capabilities.\u201d<\/span><\/p>\n
