SMAREG9 Freiberg

20 MW, 20 MWh (1 hours) in Freiberg, Sachsen, registered as operating since 12 February 2024. 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
SMAREG9 FreibergSEE913795928759202012 February 2024Lithiumunder 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.

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.
