Batteriespeicher Gersthofen
20 MW, 28 MWh (1.4 hours) in Gersthofen, Bayern, registered as operating since 2 June 2025. Everything on this page is read from Germany’s register of power units and the other published records named beside each fact.
What it is
The register holds this battery as two units.
| Unit | Register number | MW | MWh | Commissioned | Battery | Grid operator check |
|---|---|---|---|---|---|---|
| Gersthofen BS1 | SEE991039363757 | 13 | 12 | 2 June 2025 | Lithium | checked |
| Batteriespeicher Gersthofen 2 | SEE995288152438 | 7.5 | 16 | 2 July 2026 | Lithium | under check |
Power is the net power the operator registered, the most the unit may feed into the grid. Energy is the usable capacity of the unit’s installation. A grid operator check marked “checked” means the grid company has confirmed the entry; “under check” means it has not yet. On the large sites we compared, the register’s commissioning date often came months before the owner’s announced start, which suggests it records first energisation.

What this page cannot show
Germany publishes no battery’s metered output. On 11 October 2026 we checked the four public sources that might carry it: the ENTSO-E Transparency Platform, SMARD, the yearly EEG data and the transmission companies’ redispatch records. None gives the output of any German battery, one by one or as a fleet. So this page cannot say what the battery exported, imported or earned, as Britain’s battery pages do.
