The Viking Link project, the underwater interconnection between the UK and Denmark, is currently being implemented – pv magazine Spain

It is a joint venture between the British multinational electricity company National Grid and the Danish state-owned Energinet. It includes an investment of €1,970.7 million.

Virgin Link, described as the world's longest land and underwater link, has begun commercial operations between the UK and Denmark, a £1.7 billion (€1,970.7 million) joint venture between Britain's National Grid and Energinet, the Danish electricity system operator. .

The marine high-voltage direct current (HVDC) line is scheduled to initially operate with a capacity of 800 megawatts, and will reach 1.4 gigawatts during the current year.

Its construction began in 2019, although the project has been in development for more than a decade; The expected useful life of the cable is more than 40 years.

The 764-kilometre extension, which measured between the Baker Finn substation, in Lincolnshire, on the mid-west coast of England, and Refsing, in South Jutland, Denmark, “will allow power to be transmitted to up to 2.5 million British homes”. Through the waters of the United Kingdom, the Netherlands, Germany and Denmark,” he explained in a statement.

According to the information, National Grid estimates that Viking Link will save UK consumers £500 million (€579.62 million) in the first 10 years “due to cheap imported energy from Denmark” from excess energy from wind turbines and solar plants.

At each end of the Viking Link there is a conversion station, where power is converted to the correct frequency before being transmitted to each country's transmission systems.

Siemens Energy built the converter station in the UK, while Energinet built it on the Danish side. It should be noted that Siemens Energy designed, installed and commissioned the electrical installations on both sides.

Information abounds that the HVDC underground cable was manufactured by the Prysmian Group, installed by Balfour Beatty, laid on the seabed by a specially designed ship, the Leonardo Da Vinci, and then buried with Asso trenchers.

This is the sixth interconnection cable from National Grid, which developed the first with France in 1986, and then four more in succession: a second link with France (IFA2) and additional connections with the Netherlands (BritNed), Belgium (Nemo Link) and Norway (Sea Link). North).

In early 2023, National Grid announced joint plans with TenneT for a new 1.8 GW interconnector between the UK and the Netherlands, called LionLink.
