On 27 May 2021, German chancellor Angela Merkel and Norwegian prime minister Erna Solberg ceremonially commissioned NordLink by jointly pressing a digital button, officially inaugurating the "green cable" that exchanges German wind power with Norwegian hydropower and connects the German and Norwegian AC grids via converter stations at Wilster and Tonstad.
In April 2021, NordLink entered full commercial operation when TenneT, Statnett and KfW formally took over the 1.4 GW HVDC interconnector from converter supplier Hitachi ABB Power Grids, marking the end of the trial period and the transition to regular service. The 623 km "green cable" between Norway and Germany is now fully operational, reliably integrated into the electricity market and expected to supply around 3.6 million households with climate-neutral energy by exchanging Norwegian hydropower with German wind power.
On 31 March 2021, trial operations of the NordLink HVDC interconnector were successfully completed and the project consortium (Statnett, TenneT and KfW) formally took over the system, including the onshore converter stations in Norway and Germany, from Hitachi ABB Power Grids and cable suppliers Nexans and NKT, marking the end of commissioning and the transition of NordLink into the operational phase.
NordLink achieved first power on 9 December 2020, when trial operation began and the 623 km HVDC cable between Tonstad in Norway and Wilster in Germany was made available to the electricity market for the first time. The consortium partners Statnett, TenneT and KfW, together with suppliers Hitachi ABB Power Grids, Nexans and NKT, used this trial phase to test that facilities and systems in both countries operated correctly while starting commercial power exchanges of Norwegian hydropower and German wind energy.
In June 2020, NKT was awarded a contract for the German section of the NordLink interconnector to supply and install 154 km of 525 kV submarine DC cable and 54 km of underground DC cable, along with a five-year service agreement tailored to the project’s requirements.
In 2017, the European Investment Bank (EIB) signed a €300 million loan agreement with Norwegian TSO Statnett to finance its share of the NordLink interconnector, a 1,400 MW, ~624 km HVDC link between Norway and Germany that supports renewable integration and security of supply.
First cable laid on seabed in Vollesfjord, Vest-Agder, Norway. Nexans C/S Skagerrak deployed 525 kV mass-impregnated cables.
Nexans awarded EUR 500m contract to design, manufacture and install two 525 kV MIND HVDC cable subsystems for NordLink.
On 16 September 2016, project partners TenneT, Statnett and KfW (via KfW IPEX-Bank) held a groundbreaking ceremony and symbolic cable pulling at Wilster, Germany, to mark the start of construction of the German converter station and associated works for the NordLink subsea HVDC interconnector between Norway and Germany.
In 2015, the NordLink consortium of Statnett, TenneT and KfW awarded Nexans a contract worth about €500 million to design, manufacture and install two 525 kV mass-impregnated HVDC cable subsystems for the 1,400 MW interconnector between Norway (Tonstad) and Germany (Schleswig-Holstein), with a total cable length of around 700 km laid mainly offshore using the C/S Nexans Skagerrak vessel and Capjet trenching system.
