Viking Link connects UK and Danish grids

The 475-mile capacity link is claimed to be the longest land and subsea cable in the world, running from Bicker Fen in Lincolnshire to southern Jutland, Denmark. With both countries rapidly expanding their offshore wind power assets, Viking Link is set to play a central role in the ‘North Sea super grid’ that is currently taking shape.

According to National Grid, the interconnector is capable of powering around 2.5 million homes and will deliver £5.2bn in benefits to UK consumers. Since it commenced initial operations in December 2023, Viking Link has transported 1,733GWh of power between the two countries. In it’s first year it is expected to save 600,000 tonnes of carbon emissions.  

“Physical connections to other countries are central to the international collaboration which sits at the heart of the energy transition we are undergoing,” National Grid CEO, John Pettigrew said in a statement.

“In an ever-changing global energy market, the value that connections like Viking Link can provide to national energy security cannot be understated. Over its lifespan, this record-breaking connection will deliver over five billion pounds in efficiencies for UK consumers, allow us to trade hundreds of gigawatts in surplus power, and provide an indispensable tool in guaranteeing the continued reliability of our energy system.”
