Cooperation agreement affirms German-Swedish direct current project "Hansa PowerBridge"

Hansa PowerBridge

A new DC high-voltage submarine cable should improve the interconnection with the Swedish and German electricity grids. The Hansa PowerBridge is a joint project of transmission system operators Svenska kraftnät and 50Hertz.

The project

The interconnector is designed as a high-voltage direct current (HVDC) transmission cable. The connection should have an initial capacity of about 700 megawatt. The length is approximately 300 km. The German grid connection point for the cable coming from southern Sweden is planned in Güstrow, Mecklenburg-Western Pomerania. Commissioning is expected for 2025/26.

Benefits of the connection

German consumers will benefit from the enormous Scandinavian hydropower capacities. Inversely, electricity surpluses can be exported from the north-east of Germany to Scandinavia in case of strong winds.

The interconnector project is therefore an important step towards a common European electricity market. It improves the security of supply and enables an even more efficient use of the renewable generation capacities across the border.

Best perspectives

Together with the direct-current lines planned in Germany, the Hansa PowerBridge creates a long-distance connection from Scandinavia over the north-east to the south of Germany that is easy to control. As such, it supports the transition towards more renewable energy, both in Germany and Europe.

Project progress

In the coming years, the exact technical design of the interconnector will be developed and the necessary permits will be obtained. The tendering process for cables and converters is planned for 2021.

The basis for the cooperation of the coming years is a common cooperation agreement on the realisation phase, which was signed by 50Hertz and Svenska kraftnät on the 19 January 2017.
