Why now
- Rystad-linked data frames 2025 as an inflection point and projects faster 2026 additions
- China reported late-2025 grid connection of a 12.8 GWh storage cluster
- New U.S. procurement agreement targets 2028–2030 utility-scale deployments
Why it matters
- BESS surpassing pumped hydro signals a shift in grid-scale storage mix
- Mega-projects and multi-GWh deals indicate larger, longer-dated build pipelines
- Domestic supply-chain tie-ups may shape U.S. project delivery timelines
