North Sea Link


The world’s longest subsea interconnector linking the UK and Norway

What is North Sea Link (NSL)?

North Sea Link is a 720 kilometre subsea interconnector linking the electricity systems of the UK and Norway.

The 1400 megawatt interconnector stretches from Blyth in the UK, across the North Sea, to Kvilldal in Norway.

By enabling the sharing of renewable energy between the two countries, North Sea Link delivers offers consumers at both ends access to cleaner and more secure energy.

Linking Nordic and British energy markets will bring a number of benefits, including:

  • Providing opportunities for shared use of renewable energy – helping both countries to meet domestic and international renewable and climate change targets.
  • Increasing the security of electricity supplies for both countries.
  • Providing additional transmission capacity for electricity to be traded between both countries, supporting economic growth in Norway and the UK.
