Germany adds 6.57 GWh of battery storage in 2025, total hits 24 GWh

Germany added an estimated 6.57 GWh of stationary battery storage capacity in 2025, an increase of about 8% year on year, lifting total installed capacity to roughly 24 GWh. Growth was driven by industrial and large-scale systems, even as home storage installations declined alongside weaker rooftop solar demand.

Around 530,000 new battery storage systems totaling about 5.84 GWh have been commissioned and registered in Germany, with late registrations expected to lift added capacity to 6.57 GWh. That would mark an increase of roughly 500 MWh, or 8%, from 2024, signaling a return to growth after last year’s decline.

A comparison of battery storage systems registered and commissioned in 2024 (excluding late registrations) with the latest figures for 2025 shows divergent trends across market segments. While expansion in the home storage segment has declined compared with the same period last year, the industrial storage segment continues to grow steadily, and the large-scale storage segment is experiencing dynamic growth.

The home storage segment recorded an expansion of 4.19 GWh in 2025, representing a decline of 6.4% compared with the previous year.
