“Our plan is to use our manufacturing footprint in the US. We believe that’s one of our strong advantages. Obviously, we’re a big player in this market, and we have one of the strongest footprints in the US, and we’ve proven we can scale a battery plant and produce at the right quality, the right reliability, on time, for our customers.”
Meanwhile, the Gen2 Grid On BESS, which debuted at the American Clean Power Association (ACP) CleanPower 2026 conference in Texas a couple of weeks ago, will join the first-generation product on the US market next year. The 20-foot standard ISO container solution features 5MWh usable energy storage capacity and is available in 1-hour, 2-hour and 4-hour configurations.
“Grid On is our new platform for our energy storage business, which uses cells built in our plants here in the US, using the same core technology as we’ve grown up with in our EV business, and now we’re converting that to energy storage,” Schnell says of the lithium iron phosphate (LFP) BESS.
‘Unique’ safety features and flexible configuration
The second-generation product increases energy density by 20% due to “incremental improvements in product evolution,” and comes with two safety features that SK On claims are “unique.”
