This 9 September 2026 review separates global storage statistics from home-battery design. Market growth determines neither your required reserve nor installed system price.
Dated source
IEA published Global Energy Review 2026 on 20 April 2026. Its storage chapter estimates 108 GW of global additions in 2025, with around 80% at utility scale.
Statistical scope
These are power figures, not home-battery energy capacities. The remainder includes commercial and residential users; the figures do not measure Ukraine’s domestic market.
Design implications
Design needs usable kWh, continuous and peak power, BMS, temperature limits and inverter compatibility. Compare warranty conditions and permitted operation, not cell price alone.
Client implications
Request a complete installed system with protection, transfer and service. Utility-scale data cannot become a private-home estimate without a local quotation.
Uncertainty and review
Local prices, delivery times and model availability are not established here. The next editorial review target is 9 October 2026; verify commercial terms at procurement.
| Item | Parameter | Check / result |
|---|---|---|
| Global statistics | 2025: 108 GW | Power |
| Home backup | Usable kWh | Scenario |
| Procurement | Complete system | Current quotation |
What this means for your project
Use market reporting for context and measured loads for sizing. Compare complete systems against the same backup scenario.
