Licence application submitted for Norway-Scotland interconnector

NorthConnect has applied for a licence to build an interconnector between Peterhead in Scotland and Simadalen in western Norway.

The interconnector is planned to be a 500kV 1400MW HVDC subsea cable,  650km long. It is planned to go into operation in 2022. The promotors say it will improve security of supply in hydro-based Norway in dry years, and in Great Britain in periods with negative power balance (low wind, low solar, high demand).

The NorthConnect KS consortium comprises AgderEnergi, E.Co, Lyse and Vattenfall. SSE withdrew from the project.

The cable will be the second between the UK and Norway. NSN, a joint project by network companies National Grid and Statnett, will be connected to the GB system at Blyth in Northumberland and the Norwegian system at Kvilldal in Rogaland. Contracts have been placed for that project, which will require a longer cable – 750km – and is also rated at 1400MW.
