Solarpark Lärz-Rechlin (Speicher)

6.9 MW, 7.5 MWh (1.1 hours) in Rechlin, Mecklenburg-Vorpommern, registered as operating since 25 October 2023. 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.

UnitRegister numberMWMWhCommissionedBatteryGrid operator 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.

Who runs it and who owns it

Operator in the registerCommercial register entry, as the operator gave itSeat
RheinEnergie Solar GmbHAmtsgericht Köln HRB 76450Köln, Nordrhein-Westfalen

Owner. Stadtwerke Köln group (municipal; RheinEnergie called a 'kommunale Unternehmen' by ZfK, 24 Jul 2023), through RheinEnergie AG. Reported in the trade press and not yet confirmed by the owner or the commercial register. Evidence: Solarserver, 5 June 2024: "Der Kölner Versorger RheinEnergie hat in Mecklenburg-Vorpommern einen Solarpark". 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.

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.

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.
