Price signal
not published
No published prices and no reliable tender data — we leave this null rather than guess. Directional guide: Korean NCA systems trade at a substantial premium to Chinese LFP (global ex-China turnkey average ~$125/kWh per BNEF 2025; US installed $230–320/kWh); the SBB 1.5 positions at the top of the market (20-year warranty, >95% RTE). Its large Tesvolt (Germany) contract was undisclosed.
