German BESS Market Faces 9GW Capacity-Market Exclusion as Grid-Fee and Connection Rules Cloud Growth

Summary
Germany’s grid-scale battery market is still expanding with larger, longer-duration projects, but developers face unresolved policy risks around grid fees, flexible connection agreements and access to the capacity market.
BNetzA has set grid fees at €4-7/kW/year for large storage projects coming online after Aug. 4, 2029, a level analysts called manageable, while a proposed dynamic fee from 2032 still faces operator resistance.
The first two capacity-market auctions this year—totaling 9GW—are expected to exclude batteries because rules favor gas plants, though 2GW of duration-agnostic tenders next year could open a path for longer-duration BESS.
Flexible connection agreements and the grid-connection backlog remain the bigger near-term constraint, with restrictions varying widely by operator and financing for projects above 100MW increasingly tied to tolling agreements.
Transmission and distribution operators still hold outsized power over grid access, and weak digitalization is slowing approvals, leaving Germany’s strong battery buildout dependent on more transparent and standardized connection processes.
