Germany adds almost 4.59 GWh of battery storage already this year

The market data register of Germany’s Federal Network Agency (Bundesnetzagentur) lists 2,093,855 battery storage systems with a gross output of 15.24 GW and a usable storage capacity of 23.16 GWh.

The data is not entirely accurate however, as it features balcony storage systems listed as having 800 “kilowatt” capacities. That figure should be 800 watts.

The register indicates 362,537 battery storage systems were added in the year to Sep. 5, with gross output of around 2.64 GW and just under 4.59 GWh of storage capacity. As expected, solar-linked home storage systems dominate, especially in connection with increasingly popular balcony set-ups.

The data indicates 113,703 balcony storage systems with a maximum size of 2 kW were added in the year to Friday, to add 96.1 MW/756 MWh of storage capacity. Those systems were among the 361,702 batteries with a maximum scale of 40 kW which were added this year. That larger pool has a total capacity of 1,934 MW/3.6 GWh.

Some 732 “commercial storage” systems – from 40 kW to 1 MW in scale – were commissioned in the year to Friday. They have a total capacity of 94.1 MW/149.1 MWh recorded although that figure does include incorrectly recorded, oversized balcony storage equipment.

The register indicates 62 grid-scale storage systems were added, to Sep. 5, for 481.5 MW/836.1 MWh of new capacity.

The number of new storage systems added since pv magazine analysis of the first half of the year has risen, especially among small set-ups. Some 96,699 new battery storage systems have been added since June, with 684.9 MW/1.4 GWh of capacity. The latest figures indicate, however, additional registrations have been added for the first half of the year since pv magazine’s previous study and that is likely to be the case with the latest data.

Small systems account for most of the 15.02 GW/22.25 GWh of total battery storage capacity recorded in Germany by Energy-Charts.
