NordLink is a subsea 1,400 megawatt (MW) HVDC power cable between Norway and Germany. The over 500 kilometres (310 mi) long cable operates at a voltage of 500 kV.[1][2]

The cable is currently under test, and full operation is expected in 2021.[3]

Construction[edit]

It is estimated to cost €1.5–2 billion,[4] which was financed in 2015[5] when Statnett decided to realize the project.[6] The interconnector is planned to be installed between a new substation at Ertsmyra (near Tonstad) in Norway and Wilster substation in Schleswig-Holstein in Germany.[7] The connection is expected to be completed in 2020.[5] [8] When testing in September 2020, it accidentally imported the full 1,400 MW into Norway for almost a minute, causing cascading grid effects such as a 0.5 Hz frequency change across the Nordic synchronous area.[9] [3]

Ownership[edit]

The Norwegian state-owned company and transmission system operator, Statnett SF, owns 50% of the project, whilst the Dutch transmission system operator TenneT TSO and the German state-owned bank KfW own the other half. A cable between Norway and Germany is listed in the EU's projects of common interest (PCI).[1][10]
