Germany: the battery storage pipeline
Battery projects of 1 MW or larger registered as planned but not yet operating — 589 projects, 11.24 GW, 32.01 GWh.
What the register shows
589 battery storage projects of 1 MW or larger are registered in Germany as planned rather than operating, representing 11,240 MW and 32,011 MWh, as recorded on 22 August 2026. Registration in the Marktstammdatenregister is a legal requirement rather than a commitment to build: the pipeline is an upper bound on what will be commissioned, not a forecast.
Pipeline by planned commissioning quarter
Operators' own target dates. Slippage is the norm, not the exception.

Method and source
Every figure on this page is a count or a sum of values as registered in the Marktstammdatenregister (MaStR), published by the Bundesnetzagentur. The export behind this page is dated 22 August 2026; extraction and aggregation by kWhintel.

Baseload News adds no modelled or estimated values to this tier. Where the register is incomplete we say so rather than filling the gap. Units of 1 MW and above are treated as utility-scale; below that the register is dominated by household installations, which are aggregated here and never listed individually.
