We hear from Nikhil Koppaka, senior commercial manager for BESS owner-operator BW ESS on the big opportunities and challenges in Germany’s grid-scale energy storage market.

The grid-scale energy storage market in Germany is in a strong position but key questions around grid fees, grid connections, FCAs and the upcoming capacity market remain, speakers at the upcoming Energy Storage Summit Germany 2026 said. 

This year has seen a shift in the financing environment for merchant BESS projects in Germany for the worse.

The German regulator BNetzA’s latest draft decision on grid fees from 4 August 2029 onwards still leaves uncertainty for energy storage project business cases.

The shareholders of the 900MW Waltrop BESS project in Germany have approved key infrastructure works for the project, with full construction scheduled for the next few months.

Germany’s policymakers, regulators and energy storage industry must carefully consider the issues of grid connections and grid fees, writes Thomas Antonioli of developer Terra One.

Greater clarity in both government policy and market mechanisms could be essential if the German BESS industry is to realise its potential.

We hear from Christina Hepp, strategy director at battery energy storage system (BESS) owner-operator Green Flexibility, on the big successes and challenges in the German market today.

The German network regulator’s decision to maintain grid fee exemptions for battery storage “ensures that billions in private investment remain directed” into the market, Energy-Storage.news has heard.

Germany’s energy system regulator has confirmed that BESS projects coming online by 4 August 2029 will be exempt from charging and discharging grid fees, opening up investment again after months of uncertainty.
