Viking Link
The world's longest subsea and land electricity link.
Working with Energinet, the Danish power grid operator, we are proud to announce the launch of our record-breaking electricity interconnector between the UK and Denmark, Viking Link.

Viking Link is the world’s longest subsea and land interconnector, travelling 475 miles to join Bicker Fen substation in Lincolnshire with Revsing substation in southern Jutland, Denmark. Denmark has one of the world’s highest proportions of wind generation, so it is the perfect country to connect to, sharing clean electricity and helping the UK and EU meet 2050 net zero emission targets.

There will be huge benefits for UK consumers including cheaper, greener power and increased energy security, as the UK can call on additional power from Denmark when needed.

Initially, Viking Link will be operating at a capacity of 800MW before increasing over time to 1.4GW, powering up to 2.5 million UK homes and bringing over £500 million of cumulative savings for UK consumers over the next decade. National Grid and Energinet will be working together to bring the asset up to full capacity over the coming year.
