NordLink HVDC Interconnector

Covering a total of 623 kilometers, NordLink is an HVDC (high-voltage direct current) transmission link which will increase energy security in both countries, Norway and Germany. 

The consortium behind NordLink, which includes utilities Statnett and TenneT, has more than one important reasons for constructing the link: Among others, it supports the European Union’s target for CO2 emission reduction by allowing greater integration of renewables. The surplus wind and solar power produced in Germany, which must be used as it is produced, can be transmitted to Norway. 

Furthermore, at the other end of the link, Norway can export more stable hydropower to help Germany meet the daily power demand. With the hydropower being used as a battery to balance the wind and solar power generation, the link efficiently balances out fluctuations in demand, both daily and seasonal. 

NKT designs, manufactures and installs the world’s first 525 kV MI (mass impregnated) cable system in the German sector. It includes 154 km of submarine and 54 km of underground cable route. The system will simplify the interconnection of the grids and have the capacity to transmit 1,400 MW of renewable energy, which is enough to meet the power needs of about 3.6 million German households. 

NKT does not only supply the cable system, but also ensures top quality and precision when it comes to installation and maintenance. We carry out the installation with our state-of-the-art cable-laying vessel NKT Victoria, and guarantee safe long-term operation through a five-year cable service agreement.
