Really? 10 to 20x? That's 1,000 to 2,000% Here in the UK we've had suppliers collapse due to some "issues" involving not buying with fixed prices and end users like you and me get bills that are about 150% last year but not 1,000%.
We have (had) quite a lot of innovative suppliers that offered "green" tariffs that were backed by variable suppliers. Unfortunately the shit hit the fan and the price charged back in the day wasn't enough to cover the current rate plus enough profit to cover admin.

Timpris på elbörsen (on the first site, "vattenfall") means "hourly rate on the electricity exchange". Have a look at the rates for area 3 - Södra Mellansverige (south of the middle of Sweden) and compare with the same day last year ("jämför med - Samma dag föregående år"). You'll see that the rates average some 500 öre (5 sek, about $0.55) per kWh excluding taxes, levies, surcharges and value added tax. At the same day last year the rate averaged about 20 öre, i.e. a difference of 2500%. The rates fluctuate hourly and the last few weeks they've broken all records. The increase for the last month was +245%, averaged over the whole year rates have doubled.

Nord Pool have their own reporting on prices:
I'm quite surprised that Scandinavia is having even more problems than say the UK because you have rather a lot of useful topological features (really big hills and mountains and lakes at elevation - ie potential energy). You are also closer to the Ukraine than us for gas so that should be cheaper too.
Our consumer energy market is a bit strange. We have a national grid for eleccy and then have multiple "suppliers" who supposedly compete. The ones who went balls out have gone bust. They generally offered fixed and flexible rates based on the wholesale cost plus their margin. Then the wholesale cost went up rather a lot and they lost their margin and without money in the bank, they went bust. The govt agency for energy then enforced other suppliers to take us on. So I was a customer of "Green" and now I'm a customer of "Shell Energy". You can be sure that Shell are not losing out in any way 8)
I've just noticed that you use the term Nordic countries - is that a better/preferred term to use than Scandinavia?
Scandanavia includes Norway, Denmark, and Sweden. The common factor there is having closely related languages and cultures. However, speaking from experience as an American, we often use "Scandanavian" as a synonym of "Nordic".
Nord Pool covers all the Nordic countries plus a lot more: https://en.wikipedia.org/wiki/Nord_Pool
Little know fact kept out of the media when we had all the flooding over winter a few years back, one nuclear power station had to be shutdown to avoid a meltdown caused by flooding.
Electricity consumption has gone up with the increase in consumer gadgets, ie computers, tablets, mobiles, big massive flat screens, sound systems ie personal cinema setups, its only natural to see electricity demands go up.
And there is not enough of some of the rare earth materials and other metals used to make or maintain electric cars on the planet unless some miners have been keeping deposits secret, so I expect some miners share prices to go up considerably in the future.
Oh, I give up.
