Amprion and Energinet drive forward offshore interconnector between Germany and Denmark

The Federal Ministry of for Economic Affairs and Energy (BMWE) and the Danish Ministry of Energy (KEFM) have signed an agreement for a strategic energy partnership at the North Sea Summit in Hamburg. This also includes a potential offshore interconnector to be implemented by Amprion and Energinet.

The agreement signed between Germany and Denmark builds on existing European initiatives with transmission system operators and energy companies. It is another important step towards transforming the North Sea into the “green power plant” of Europe. The European partners want to use electricity generated by offshore wind farms more efficiently and to make the planning of offshore wind energy coordinated and cost-efficient.

Amprion and the Danish grid operator Energinet are supporting the ministries with the cooperation for the planning of a potential hybrid interconnector in the North Sea. The “TYSDAN Hybrid Interconnector” project makes a decisive contribution to achieving the European energy and climate targets. The partners plan to use innovative technology on the high seas: as a world first, a circuit breaker for direct current would be installed on an offshore platform in the networking of wind farms. The technology sets new standards in the industry and paves the way for the further integration of the European electricity grid in the North Sea region.

Dr Christoph Müller, CEO of Amprion: “Our planned interconnector between Germany and Denmark will strengthen the resilience of the European electricity grid and leverage efficiency potential. The Joint Declaration of Intent signed today is a milestone and impetus to continue planning quickly together with our Danish partners. At the same time, this sort of European colloaboration show how important the long-term investment capacity of transmission system operators is.”

Thomas Ebeborg, President and CEO of Energinet: “Our ministries have reaffirmed their intention to intensify cooperation in connecting the German grid with Danish offshore wind energy in the North Sea. We are pleased that they are expressly supporting the further exploration of the potential of an offshore interconnector between our countries through Amprion and Energinet.”

Innovation on the high seas, for an efficient and resilient grid in Europe

The project by Amprion and Energinet could connect two Danish offshore wind farms in the North Sea, each with a capacity of two gigawatts, with the power grids in Germany (Lippe) and Denmark (Revsing). This connection will allow the electricity from the Danish wind farms to be transmitted more efficiently to the western German consumption centres. Cross-border networking makes it possible to react better to fluctuations in generation and consumption - this reduces grid bottlenecks and increases security of supply in Germany and Denmark. For consumers in Germany, this will lead to lower electricity prices in the long term.

At the end of 2025, a preliminary feasibility study was successfully completed. With the signed declaration, the next phase of development begins together with the BMWE and the KEFM. Amprion and Energinet are now preparing for the upcoming regulatory approval procedures.
