Bundesnetzagentur releases 2024 battery storage grid connection data

Bundesnetzagentur published its 2024 figures on grid connection applications and approvals for battery storage on 12 November 2025. The release is the regulator's own data, making it a primary reference for tracking how Germany's distribution and transmission networks are absorbing the BESS pipeline.

The publication covers both the volume of applications submitted and the number of approvals granted across 2024. The gap between the two, where it exists, is the clearest available signal of grid queue congestion for storage projects in Germany. Bundesnetzagentur did not include a 2023 comparator in the release per the available summary, so trend direction cannot be stated with confidence at this stage.

For analysts sizing the German BESS opportunity, connection approval rates are a harder constraint than permitting or procurement. This dataset is the official input for that calculation. Full figures are available directly from the regulator.
