Germany and Denmark have signed an agreement on a strategic energy partnership at the North Sea summit in Hamburg. The agreement includes a potential offshore interconnector to be developed by Amprion and Energinet. The bilateral agreement builds on existing European initiatives involving transmission system operators and energy companies. It aims to improve the use of offshore wind generation and to support coordinated and cost-efficient planning of offshore wind energy in the North Sea region.
Amprion and Energinet are supporting the ministries in planning a potential hybrid interconnector in the North Sea under the TYSDAN Hybrid Interconnector project. The project is intended to contribute to European energy and climate objectives. The partners are assessing the use of new offshore technologies, including the possible installation of a direct current circuit breaker on an offshore platform for wind farm interconnection.
The project could connect two Danish offshore wind farms in the North Sea, each with a capacity of 2 GW, to the electricity grids in Germany (Lippe) and Denmark (Revsing). The connection would enable more efficient transmission of electricity from Danish offshore wind farms to demand centres in western Germany. Cross-border interconnection is expected to improve system flexibility, reduce grid congestion and strengthen security of supply in both countries.
A pre-feasibility study was completed at the end of 2025. Following the signing of the agreement, the partners are entering the next development phase with the German Federal Ministry for Economic Affairs and Energy and the Danish Ministry of Energy. Amprion and Energinet are preparing for the upcoming regulatory approval processes.
