Denmark and UK plan subsea interconnector

Denmark’s grid operator Energinet and its UK counterpart National Grid want to build the first electricity interconnection between the countries.

Work on a feasibility study will begin today to examine the possibilities for a subsea cable.

With the two countries being the European leaders in wind power, such a link would allow them to export renewable energy to each other across the North Sea.

Terry McCormick, head of UK and European business development at National Grid, said: “More interconnection with Europe supports the integration of renewable energy and gives us more options to balance our network in UK.” He added that a UK-Denmark link would “meet European objectives of bringing more competition to the market”.

Torben Glar Nielsen, executive vice-president of Energinet’s electricity division, said: “Both Great Britain and Denmark are planning for integration of future very high amounts of wind power. Therefore, the study will also look at how the new cable would help both countries export and import renewable power, as well as connecting into a future North Sea ‘super grid’ to connect offshore wind power.”

The study will look at different technical solutions, potential routes, the capacity of the cable and the potential commissioning timetable.

The UK already has three operational cable interconnectors with Ireland, France and the Netherlands, and it is exploring links with Norway, Belgium and Iceland.

Denmark has interconnectors with Norway, Sweden and Germany, is building a further link with Norway and is investigating the possibility of establishing an interconnection with the Netherlands.
