NordLink is a subsea 1,400 megawatt (MW) HVDC power cable between Norway and Germany, opened in May 2021.

[6][9] 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.

[12] Grid constraints inside Norway and Germany sometimes restrict NordLink capacity to less than maximum.

[13][14] 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).
