SEE_2025_4642_Föhren_BESS
20 MW, 55 MWh (2.8 hours) in Föhren, Rheinland-Pfalz, registered as operating since 18 December 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 |
|---|---|---|---|---|---|---|
| SEE_2025_4642_Föhren_BESS | SEE926245506438 | 20 | 55 | 18 December 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.
Who runs it and who owns it
| Operator in the register | Commercial register entry, as the operator gave it | Seat |
|---|---|---|
| Schoenergie Batteriespeicher Föhren GmbH | Amtsgericht Wittlich HRB 46439 | Föhren, Rheinland-Pfalz |
Owner. Schoenergie, a family-owned German renewable energy company. Reported in the trade press and not yet confirmed by the owner or the commercial register. Evidence: enspired case study, 2 September 2026: "Schoenergie is a family-owned renewable energy company based in Germany.". Checked 16 October 2026. Every battery of this family.
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.
