Reform of the German Electricity Grid Tariff System: Should Producers Pay Grid Charges?

In this article for Oxera, authors Dr Philipp Schliffke, Dr Rupert Booth & Albert Fock (Oxera) analyze the implications of a May 2025 discussion paper published by the German energy regulator, Bundesnetzagentur (BNetzA), which could lead to a fundamental overhaul of the country’s electricity grid charging system. Prompted by a European Court of Justice ruling that found Germany’s existing grid charge regulations incompatible with EU electricity market directives, the BNetzA must introduce a new regulatory framework by 2029.

The authors explain that this overhaul offers a timely opportunity to align grid charges with the evolving realities of Germany’s energy landscape—particularly the shift toward net zero emissions, the rapid increase in renewable energy generation, and the rise of decentralised and prosumer-based electricity models. Current tariff structures, which place cost burdens primarily on consumers and are based on energy usage, may no longer be suitable given the new dynamics in electricity production and demand.

The BNetzA’s consultation centers on five key questions: whether electricity producers should also contribute to grid charges, how tariffs should be structured, the potential for regionally and temporally dynamic pricing, the harmonization of local distribution grid charges, and how electricity storage should be treated within the charging system. The answers could reshape the cost-sharing mechanisms of the energy transition and better support grid stability in the face of growing electricity demand and decentralised supply…
