National Grid starts construction on UK-Denmark interconnector

Britain’s National Grid has started construction of the Viking Link, an electricity interconnector project between Britain and Denmark.

Viking Link is a joint venture between National Grid Ventures, part of National Grid, and the Danish electricity system owner and operator, Energinet. The 1.4 GW high voltage electricity interconnector will be the longest in the world when completed, spanning 765 kilometres between Lincolnshire in eastern England and South Jutland in Denmark. Siemens Energy will construct the British and Danish converter stations on both ends of the interconnector link. Once completed by the end of 2023, the Euro 2 billion ($2.3 billion) subsea electricity cable will have the capacity to be able to supply renewable energy to provide power to 1.5 million UK homes.
