- Bundesnetzagentur will publish the first framework for the future BESS grid fee design at the end of May or the beginning of June, according to Karsten Bourwieg speaking at BBDF 2026 in Frankfurt.
- The release would mark the first concrete signal of where the regulatory framework is headed within Germany's ongoing general network charge system for electricity (AgNes) process.
- One of the key questions on the first day of the Battery Business & Development Forum (BBDF) 2026 was whether Germany's grid fee exemption for battery storage will end, and if so, when.
- Attendees at the second annual BBDF event have been waiting months for clarity on grid fees, making the announcement a partial but significant update.
- The framework publication will occur as the AgNes process continues, connecting the BESS-specific rules to Germany's broader electricity network charge reform.
Why it matters: The framework's release by early June ends months of regulatory limbo for German battery storage developers and investors who have been awaiting clarity on whether grid fee exemptions will be eliminated. Because the BESS exemption currently shapes project economics across Germany's storage pipeline, the Bundesnetzagentur's first concrete framework under the AgNes process directly determines the financial viability of projects that have been on hold.
