SK On unveiled a new energy storage system (ESS) product in the United States as it moved to target the North American market.
SK On said on the 4th that it participated as a sponsor in Cleanpower 2026, held in Houston from the 1st to the 4th local time, and hosted a customer invitation event near the exhibition hall in downtown Houston.
Timed with Cleanpower 2026, the event was organized to strengthen communication with customers in the United States and to introduce SK On's ESS business strategy and product competitiveness. At the event, SK On unveiled its ESS product brand "GRIDON" and the new "GRIDON Gen2" product. GRIDON is SK On's ESS brand that carries the meaning of "turning on the grid."
GRIDON Gen2 is a next-generation ESS product under development that reflects the U.S. market and customer needs, with mass production targeted for the third quarter of 2027. In line with the trend of the ESS market shifting from traditional direct current (DC) blocks to alternating current (AC) blocks integrated with power conversion systems (PCS), it is designed for use not only with DC blocks but also with AC blocks.
SK On plans to accelerate the expansion of its ESS business based on the large-scale production capacity of its U.S. plants. SK On has secured stable local production capacity through a total of four plants: the standalone Georgia plant SK Battery America Plants 1 and 2, the HSBMA (Hyundai SK Battery Manufacturing America) plant scheduled to start operations this year, and the standalone SK On Tennessee plant in Tennessee.
SK On is targeting orders of more than 20 GWh (gigawatt-hours) in the global ESS market this year. It is currently in talks with multiple U.S.-based customers on ESS supply contracts totaling more than 10 GWh.
Choi Dae-jin, head of SK On's ESS business division, said, "The United States is a key market where demand for renewable energy expansion and grid stabilization is growing simultaneously," adding, "We will continue to broaden touchpoints with customers, actively promote our differentiated product competitiveness and fire safety-related technologies, and further strengthen our presence in the North American ESS market."
