The proposed expansion with the addition of the Sørvest F and Vestavind F areas changes the assumptions based on the analysis from 2012 and a strategic impact analysis must therefore be carried out for the effects of the capacity expansions, according to the Norwegian government.

The government has also commissioned NVE to carry out a strategic impact assessment of the Vestavind B area, which is said to have good wind conditions and a lot of existing infrastructure related to established industries and interests in the area.
