B1 Batterien CR01
6.5 MW, 38 MWh (5.9 hours) in Schenkenberg, Brandenburg, registered as operating since 14 May 2018. 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 |
|---|---|---|---|---|---|---|
| B1 Batterien CR01 | SEE914355585900 | 3.7 | 3.7 | 24 March 2023 | Lithium | checked |
| Batteriespeicher Cremzow MaStR and owner disagree | SEE963224111412 | 2.8 | 35 | 14 May 2018 | 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 |
|---|---|---|
| ENERTRAG Solarfeld Kreuz Uckermark GmbH ＆ Co. KG | Amtsgericht Neuruppin HRA 2439 | Schenkenberg, Brandenburg |
| Enel Green Power Cremzow GmbH ＆ Co. KG | Amtsgericht Neuruppin HRA 3189 | Schenkenberg, Brandenburg |
We have not yet traced the owner behind ENERTRAG Solarfeld Kreuz Uckermark GmbH ＆ Co. KG and Enel Green Power Cremzow GmbH ＆ Co. KG. The commercial register holds it, and the owners page lists every family traced so far.
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.
Who trades it and what it is built from

Tender award

The innovation tenders pay a market premium to solar or wind paired with storage. The award lists are the Bundesnetzagentur’s. A bidder that differs from today’s operator dates a change of hands, or a spelling difference.

Doubts about this entry
MaStR and owner disagree. Batteriespeicher Cremzow, Enel Green Power, registered at 2.8 MW net power against 22 MW gross, with 34.6 MWh. Its builders announced it as a 22 MW battery (pv magazine, 20 May 2019, https://www.pv-magazine.com/2019/05/20/enertrag-enel-and-leclanche-commission-22-mw-storage-project-in-germany/). Counted at the register’s 2.8 MW, the power the operator declared for the grid.
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.
