In Germany, approximately 530,000 new battery storage systems totaling approximately 5.84 GWh have been commissioned and registered, with late registrations expected to increase additional capacity to 6.57 GWh. That would represent 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 deployed in 2024 (excluding late registrations) with the most recent figures for 2025 shows varying trends across market segments. While expansion in the home storage segment has slowed compared to 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 a growth of 4.19 GWh in 2025, which represents a decrease of 6.4% compared to the previous year.
