It adds to the problems/costs, but doesn’t make it impossible.

In Norway, hydropower accounts for nearly 99% of the total electricity production. To meet winter demand, storage schemes are implemented in tandem with run-of-river schemes to a large extent in cold region hydropower systems. In these systems, ice creates operational constraints during winter that can lead to reductions in power production. The problems occur in the various phases of the ice regime, mainly due to frazil ice, ice runs, and ice jams. Counteracting these ice problems is usually a difficult task that involves expensive measures and possibly lost production.

A bad load of lutefisk must have hit every tech school cafeteria in Norway for them to come up with this engineering wank-a-thon, although that DC cable to Denmark is impressive. Wonder how the Field will affect the fish.

Looking on the bright side, it will provide jobs for and possibly even drown many of the Muslim immigrants who are bedeviling the place.
