On behalf of the German Federal Network Agency (Bundesnetzagentur), Consentec, together with the Chair of German and International Mining and Energy Law at Clausthal University of Technology, has prepared a study on the further development of the electricity network tariff system. The study focuses on reform options for network tariffs applicable to electricity consumers, generators, and energy storage systems, as well as approaches to dynamic network tariffs.
The study was prepared as part of the AgNes process and is now available for download on the Bundesnetzagentur’s website: https://www.bundesnetzagentur.de/DE/Beschlusskammern/1_GZ/GBK-GZ/2025/GBK-25-01-1x3_AgNes/Downloads/Gutachten_FL-Entwurf.pdf?__blob=publicationFile&v=4“
With the LeistungspreisPlus model, TenneT Germany and TransnetBW GmbH have developed a market design for integrating distributed Energy Resources into congestion management that is both practical and avoids conventional Inc-Dec gaming. In a qualitative expert assessment, Consentec and Neon Neue Energieökonomik evaluated the design with respect to incentive compatibility, practical feasibility, and economic efficiency. Open questions regarding the model’s efficiency, which could not be conclusively addressed within the project, are intended to be examined in a subsequent pilot implementation.

How can large-scale battery energy storage systems contribute not only to the electricity market but also to relieving congestion in transmission networks? A new policy paper commissioned by Amprion demonstrates how grid booster functionalities can be efficiently deployed as a market-based procured ancillary service (“System Booster”), thereby reducing grid costs and complementing the expansion of the electricity transmission network. The policy paper has been published here (ger).
Our Managing Director, Christoph Maurer, participated in a press briefing hosted by the Science Media Center (SMC) on the topic “How Could a Compromise on the Redispatch Reservation under the EEG Open the Door to a New Energy System?” Together with Prof. Dr. Thorsten Müller and Prof. Dr. Anke Weidlich, he discussed the implications of potential regulatory adjustments for the further development of the energy system. A recording of the event is available here.
How can renewable energy sources, storage facilities, and power grids be better coordinated in the future? In a recent article published in ifo Schnelldienst, our Managing Director, Christoph Maurer, explains why the energy transition is above all a coordination challenge—and why more efficient price signals and regional markets could play a key role in limiting system costs while ensuring security of supply.
