What is North Sea Link (NSL)?

Commissioned in 2021, North Sea Link is a joint venture between Norwegian Transmission Operator Statnett and National Grid. 
The 720 kilometre subsea interconnector is the longest in the world and connects Norway to Great Britain. 

Linking Nordic and British energy markets brings a number of benefits:

  • Providing opportunities for shared use of renewable energy, helping both countries to meet domestic and international 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 Great Britain.
