Capacity continued to climb quickly
The U.S. Energy Information Administration reported that operational utility-scale battery storage stood at 43.6 GW at the end of 2025. Operators added 8.3 GW during the first six months of 2026, bringing nameplate battery-storage capacity to nearly 52 GW.
The near-term project pipeline is also large
EIA says operators reported plans for another 14 GW in the second half of 2026 and 54 GW over the following two and a half years. Planned projects are not the same as commissioned capacity, so Melnti keeps those figures separate.
Why Melnti tracks this
Grid-scale storage does not determine which home battery a consumer should buy, but rapid deployment can influence interconnection practice, market familiarity and the broader storage supply chain. Household decisions still require exact equipment compatibility, local tariffs, backup goals and a qualified installer.
