Norway’s Statnett to start testing North Sea Link in July 2021 [free access]

June 8, 2021

Norway’s transmission system operator (TSO) Statnett is set to start testing the North Sea Link, a subsea electricity interconnector with the UK, in July 2021.


National Grid Electricity Transmission plc (NGET) of the UK and Statnett are building this electricity interconnector between Kvilldal in Norway and Blyth in the UK. Also known as the North Sea Network Interconnector, the ±500 kV, high voltage direct current (HVDC) link will be the world’s longest subsea electricity cable, measuring a length of 720 km, with a full capacity of 1,450 MW. The grid operators will begin by sending 700 MW along the cable both ways, before ramping up to full voltage by September 2021.


Once operational, the 1.4 GW electricity interconnector could allow the UK to import clean energy from Norway to power up to 1.4 million homes.
