The publication of the Q&A comes just after regulator BNetzA published its draft decision document regarding long-term grid fees in the German market, a key question for energy storage project bankability, on 6 August (the questions were drafted before its publication).
We heard from another event speaker, Nina Schmüser, regulatory affairs manager in Germany for independent power producer (IPP) Grenergy, on the day of the decision document’s publication.
What are the key trends, major successes and achievements, and challenges still to be overcome in the German energy storage market?
Germany has moved from a promising niche to Europe’s most dynamic large-scale storage market. Q1 2026 saw a record build-out of roughly 2.2GWh (+38% vs. Q1 2025), the installed base stands at around 14GW, and 2026 could add 8 to 10GWh.
The merchant business case has been proven: negative price hours rose from 69 (2022) to 573 (2025), solar capture rates have fallen below 60%, and intraday spreads regularly exceed €150/MWh within an hour.
