NordLink

NordLink is a 623-kilometer (387 mi) high-voltage direct current (HVDC) submarine power cable connecting the electricity grids of Norway and Germany. It has a transmission capacity of 1,400 megawatts (MW) and operates at a voltage of ±525 kV. The cable runs between Tonstad in Norway and Wilster in Germany.

The purpose of NordLink is to facilitate the exchange of renewable energy between the two countries. Norway's hydropower resources can be used to balance Germany's intermittent wind and solar power generation. Conversely, Germany can supply electricity to Norway during periods of low hydropower production. This promotes energy security and contributes to the integration of the European energy market.

NordLink is owned and operated by a consortium comprising Statnett (Norway's transmission system operator) and TenneT (the German-Dutch transmission system operator). The project was completed and commissioned in 2021. The cable enhances the stability of both the Norwegian and German electricity grids and reduces reliance on fossil fuels. The interconnection also contributes to lower electricity prices for consumers by increasing competition and supply.
