A US battery storage company, NeoVolta Power, has signed a five-year supply deal with SK On, a Seoul-based battery maker, to expand its factory in Pendergrass, Georgia. From 2027 through 2031, SK On will supply 9 gigawatt-hours of lithium iron phosphate (LFP) battery cells, a type of lithium battery known for long life and stability rather than compact size. NeoVolta will assemble these cells into battery energy storage systems for commercial, industrial, and utility-scale projects, not for individual homes.
The companies have also outlined a possible second phase that could double the deal to 18 gigawatt-hours, with SK On supplying more cells for NeoVolta to turn into finished battery packs that SK On would then buy back. That part isn't finalized yet and depends on future orders.
This news doesn't involve residential batteries or home rebates. It's about scaling up domestic manufacturing of grid-scale storage equipment, which could eventually support more battery projects on the electric grid and help make the LFP battery cells and packs used in some home battery systems more available in the US. For a homeowner, this doesn't create any new program, rebate, or direct action to take. It's a sign that battery storage manufacturing is growing in the US, which over time could affect the availability and origin of battery hardware, including in home energy storage products, but there's no direct impact on your house right now.
