Viking Link
The world’s longest onshore and subsea HVDC interconnector stretching a record-breaking 765km (475 miles), Viking Link is now enabling the sharing of clean electricity between the UK and Danish power grids.
Viking Link is helping to deliver the energy transition by sharing clean energy between the UK and Denmark.
Working with Energinet, the Danish power grid operator, the completion of Viking Link electricity interconnector joins 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.

Viking Link: the latest stories
The next step towards a North Sea super-grid
Delivering a major milestone in the UK energy transition and the next step in creating a North Sea grid, National Grid has today formally launched Viking Link, a record-breaking cable connecting British and Danish energy grids for the first time.
The UK and Denmark are now sharing clean energy
Viking Link is live! With a capacity of 1.4GW, Viking Link could enable the sharing of enough green electricity to power up to 2.5 million UK homes* and will provide access to a broader energy mix for both Denmark and the UK.
Anglo-Saxon cemetery discovered during Viking Link build
Items from an Anglo-Saxon cemetery were uncovered in rural Lincolnshire during work to build Viking Link. The finds, including jewellery, pottery and human remains, were featured on BBC2’s ‘Digging for Britain’
Viking Link power cable laying is completed
The final length of the 475-mile (765km) Viking Link interconnector has been laid and joined – forming a continuous link between the UK and Denmark for the first time.
