About the Konti-Skan HVDC cable interconnector:
The first interconnection between Sweden and the western grid in Denmark was established in 1965 with the 250 MW 250 kV Konti-Skan HVDC link across the Kattegatt, stretching from Gothenburg in Sweden to Aalborg in Denmark. The owners of the link are Energinet DK and Svenska kraftnät.
A second Konti-Skan cable rated 300 MW was added in 1988 from Lindome on the Swedish side to Vester Hassing.
