Lo stoccaggio della batteria tedesca raggiunge 22,1 GWH a metà del 2025

By the end of the first half of 2025, Germany’s official registry of energy installations recorded nearly two million battery storage systems in operation. This figure, now unofficially but safely surpassed into July , includes a gross power capacity of 14.535 gigawatts (GW) and a usable storage capacity of nearly 22.1 gigawatt-hours (GWh).

**Photovoltaic home storage systems constitute the majority of these installations, with 1.967 million small battery storage units (up to 20 kilowatts) accounting for 11.5 GW of gross power and almost 18.3 GWh of usable capacity.**

The medium segment, comprising commercial storage systems between 20 kilowatts and 1000 kilowatts, includes 14,827 facilities totaling 663 megawatts (MW) of power and over 900 megawatt-hours (MWh) of capacity. **Additionally, 323 large battery storage systems contribute approximately 2.35 GW of power and nearly 2.9 GWh of storage capacity.**

Future

The expansion appears to show no signs of slowing. The registry shows 19,720 systems in planning with a planned output of just under 4.7 GW and a capacity of just over 9.4 GWh.

Being planned are:

– 18,653 small storage systems up to 20 kW with 126.7 MW output and 515.6 MWh capacity;
– 627 commercial storage systems at 97.9 MW / 171.6 MWh;
– **And, 440 large-scale storage systems, with just under 4.35 GW / 8.72 GWh.**

Great Scott!

Well its a start but the big projects are coming in the future, most of those batteries today are just residential ones.
