Germany and Sweden want to connect their relative power grids via this direct current connection. The 300 kilometre distance will be bridged by a so-called interconnector: the Hansa PowerBridge. The interconnector serves to link various independent grids. After its completion, the Hansa PowerBridge will provide an important contribution to the stabilisation of the German electricity price, the security of the transmission system as well as to the indirect storage of electricity from renewable energy sources.
In order to efficiently bridge the large distance between both countries, the power transmission concept is based on high voltage direct current (HVDC) technology. Germany and the rest of Europe use alternating current. However, for long distances, HVDC offers greater advantages with regard to energy loss and power management.
The Hansa PowerBridge should have a capacity of about 700 megawatts and be operational in 2025 or 2026. The investment costs for the infrastructure project amount to approximately 600 million euros. This amount will be shared equally by both project partners, 50Hertz and Svenska kraftnät. 50Hertz and Svenska kraftnät are currently preparing the permit documents for the project.
