SK On Wins $1.1B LFP Battery ESS Contract with Neovolta, Accelerating Pivot from EV to Energy Storage

The Quick Take

• SK On secured a 9GWh LFP battery supply deal with US firm Neovolta Power worth approximately KRW 1.5 trillion (~$1.1B), its largest ESS contract
• Supply will run from 2027 to 2031 via SK On's Georgia plant, covering nearly half the company's annual ESS order target in a single deal
• The contract accelerates SK On's strategic pivot from high-nickel EV batteries to LFP-based energy storage amid volatile EV demand

SK On's 9GWh LFP battery supply agreement with Neovolta Power is among the largest standalone energy storage battery contracts signed by a Korean cell manufacturer, reflecting a broader strategic recalibration underway across the global battery industry. As EV demand growth has slowed relative to earlier expectations in both the US and Europe, leading battery manufacturers including SK On, LG Energy Solution, and Samsung SDI are diversifying aggressively into energy storage systems driven by grid-scale renewable integration mandates and long-duration storage policy requirements.

For SK On specifically, the deal arrives at a critical juncture where the company has faced significant financial pressure from low EV factory utilisation rates at its US and Korean plants. The pivot toward LFP battery chemistry for ESS applications addresses a segment where Chinese manufacturers CATL and BYD currently dominate globally, but where US customers increasingly prefer non-Chinese suppliers under IRA domestic content incentive structures. SK On's Georgia plant supply origin directly qualifies Neovolta's downstream projects for IRA clean energy credits — a competitive advantage the company is now actively leveraging to win US market share.

Key forward signals include SK On's progress toward its full-year 20GWh ESS order target, which this single deal brings nearly halfway to completion. Ongoing negotiations with multiple additional US ESS customers for 10GWh-plus of additional contracts are the next near-term catalyst. Investors should also watch the conversion timeline for SK On's Seosan factory LFP line and its Georgia plant reconfigurations, which will determine whether production capacity can scale in time to capture the growing US grid storage opportunity before intensifying Korean and Chinese competition.
