Electric power infrastructure in Denmark

HVDC transmission lines between Denmark and Norway

The Kontek HVDC is a long, monopolar 400 kV high-voltage direct current cable between Germany and the Danish island Zealand. Its name comes from "continent" and the name of the former Danish power transmission company "Elkraft", which operated the power grid on the Danish islands Lolland, Falster and Zealand and had the abbreviation "ek". As of today, the cable is operated by Energinet.dk in Denmark and 50Hertz Transmission GmbH in Germany.

Konti–Skan (also known as Kontiskan) is the name of high-voltage direct-current transmission line between Denmark (DK1) and Sweden (SE3).

COBRAcable (COpenhagen-BRussels-Amsterdam cable) is a ±320 kV, 700 MW HVDC submarine power cable pair between Eemshaven, the Netherlands and Endrup near Esbjerg, Denmark. The cable is jointly owned by Energinet.dk and TenneT. Its purpose is to improve the European transmission grid and thus increase the amount of variable wind power in the system while improving supply reliability. Its 700 MW capacity corresponds to an annual transmission capacity of 6.1 TWh.
