Electric power infrastructure in Norway

NorNed is a long high-voltage direct current submarine power cable between Feda, Norway and the seaport of Eemshaven in the Netherlands, which interconnects both countries' electrical grids. It was once the longest submarine power cable in the world. Budgeted at €550 million, and completed at a cost of €600m, the NorNed cable is a bipolar HVDC link with a voltage of ±450 kV and a capacity of 700 MW. NorNed is a joint project of the Norwegian transmission system operator Statnett and its Dutch counterpart TenneT. The cable system itself and the two converter stations were produce

NordLink is a subsea 1,400 megawatt (MW) HVDC power cable between Norway and Germany, opened in May 2021. The long line operates at a voltage of 500 kV DC. It consists of 54 kilometres long land cable in Schleswig-Holstein, Germany, a 516 kilometres long submarine cable between Germany and Norway and a 53 kilometres long overhead line with 140 towers in Norway.
