HVDC Hansa PowerBridge Cooperation Agreement

A new 700 MW HVDC (high voltage direct current) subsea electric cable is planned to be constructed between Sweden and Germany. The cable is refereed to as the Hansa PowerBridge. The project has been on preparation level for several years, and now it has been decided that the 300 km long interconnector will be commissioned by 2025/26.

The new agreement includes time-schedule and provisions on the technical design, project organisation, ownership structures, cost allocation, tendering, construction and commissioning of the planned interconnector.

The approximately 300 km long Hansa PowerBridge will be submarine at 200 km. The German grid connection point for the cable is planned in Güstrow, Mecklenburg-Western Pomerania. On Swedens side the cable will connect to the Swedish transmission network at Hurva in Skåne. It is expected that German consumers will benefit greatly from being connected to Scandinavian hydropower capacities. Also the cable makes it possible for Sweden to import electricity generated by strong winds in the north-eastern part of Germany .

As such it enables an even more efficient use of the renewable generation capacities across the border. This should contribute to the climate-friendly and cost-efficient generation of electricity.

The next steps in the project will be preparations for the permitting procedure (to be concluded by end of 2021), then having call for tenders for the installations (in 2022), and finally the interconnector being operational in 2025/2026. The total investment costs is estimated close to 600 million EUR, and will be evenly distributed among the two TSOs.
