The new 420 kV interconnector from Ofoten to Balsfjord became operational in September 2017, and Nedre Røssåga-Namsos underwent a voltage upgrade to 420 kV in October 2017. These are key measures in order to increase transmission capacity in the region.

Transmission capacity into and out of Western Finnmark will be good when the 420 kV Balsfjord-Skillemoen interconnector is constructed, while there will still be internal grid limitations in Finnmark County. There is a considerable resource potential and a number of plans for both new consumption and new generation, which may result in a need for new grid investments in the region.
