SMAREG12 Vöhringen I
20 MW, 42 MWh (2.1 hours) in Vöhringen, Bayern, registered as operating since 29 August 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 one unit.
| Unit | Register number | MW | MWh | Commissioned | Battery | Grid operator check |
|---|---|---|---|---|---|---|
| SMAREG12 Vöhringen I | SEE967076530902 | 20 | 42 | 29 August 2025 | Lithium | checked |
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.

The register names the operator, the company that runs the unit. The owner behind it comes from the commercial register (Handelsregister) or the owner’s own publication, as marked. The register number is the one the operator typed in; on 11 October 2026 we found it wrong or missing for 26 of the companies we looked up.

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.
