Correct. One additional problem beyond the price hike was also the fact that the price came to be wildly unstable. One day it was bascially free and the next day it was approaching 1 euro per kwh, where as before, the price usually came to about 1 NOK (10-12 eurocent) per kwh
after taxes and such, and hadn't moved significantly from that in over 10 years.
See Fig 2 here[1] for just how spiky the market became after the price hike.
Also bear in mind that Norway does most of its residential heating with resitive heating, precisely because electricity has historically been so cheap. Heat pumps are getting more popular, and burning firewood got very popular during the price hike, but basically no-one heats with gas, as there's no infrastructure to support it.
