The capacity of the North Sea Link (NSL) has been limited to 700 MW, half of actual capacity, due to an error on the UK side. The interconnector will remain sharing half capacity until 5th December 2021 or until the error is rectified, which remains uncertain.

The 1.4 GW
NSL started trial operations  on 1st October 2021. Statnett and National Grid increased the maximum capacity offered to the market from 700 MW to 1050 MW during trial operations.

Both the TSOs have announced great benefits from the early commissioning of NSL. Norway’s Statnett has reportedly earned NOK 2.9 billion (~€292 million) from its international interconnections, mainly NSL and NordLink, reducing the TSO’s share of grid rent from 2020s level.


‘It is good to see that the revenues from our international connections are so large and that the cables we have built to two new countries so far show profitability. These revenues are important when we are to invest NOK 60-100 billion in networks to support the green change of pace’, said Statnett CEO Hilde Tonne.


Meanwhile, Britain’s National Grid is expecting a ~£100 million (~€119 million) higher operating profit, mainly due to the early commissioning of
NSL and higher auction prices. Given the strong start to the year, it now expects to deliver full year underlying earnings per share (EPS) significantly above the top end of its  5-7% range, said National Grid in its 2021/22 half year results statement.

Upon full commissioning, the €1.6 million
NSL will provide enough clean energy power to 1.4 million homes, and avoid 23 million tonnes of carbon emissions in the UK by 2030. The 714 km HVDC interconnector connects Blyth in UK with the Norwegian village of Kvilldal, near Stavanger.
