South Korean battery manufacturer SK On has announced a supply agreement with US company Flatiron Energy. Under the agreement, SK On will deliver battery storage systems with a total capacity of up to 7.2 gigawatt-hours by 2030. The first projects will be implemented in Massachusetts starting in 2026. According to SK On, these systems will be containerized and based on lithium iron phosphate (LFP) cells.
Conversion of battery production lines
SK On will produce the batteries in the state of Georgia beginning in 2026. To this end, production lines for electric vehicle batteries at the companyʼs Commerce site will be converted to manufacture stationary storage systems. The cells will be delivered in modular units that are, according to the company, expandable and feature additional safety mechanisms.
Growing BESS demand for power grid
Through these efforts, SK On is expanding its commitment in the United States beyond electric mobility. The company cites a growing demand for energy storage systems for the power grid. Founded in 2021, Flatiron Energy develops and operates large-scale storage projects in North America, handling planning, construction, and long-term operation.
