North Sea Link
Connecting the UK and Norway to share clean energy.

Connecting the UK to clean, reliable energy

North Sea Link (NSL), a joint venture with Norwegian system operator Statnett. Stretching 720 kilometres under the North Sea, at depths of up to 700 metres, NSL is an interconnector capable of sharing up to 1400 megawatts of electricity – enough to power around 1.4 million UK homes.

NSL is part of our portfolio of electricity links connecting the UK to the energy systems of Norway, Belgium, France, the Netherlands and most recently, Denmark.

An incredible feat of engineering and teamwork

An international team of experts spent more than 4 million working hours over 6 years to deliver the project, finding innovative ways to get the state-of-the-art cable through fjords and mountains and across the North Sea.
