You have to consider that in many nordic countries there are very few people and a lot of natural resources, especially hydro power. That means that also in extremely expensive countries like Norway there is very very cheap electricity.
If that would be a rule for it Norway wouldn't have the most expensive gasoline either.
The best price you could get as an energy-intensive manufacturing business will be around 6 cents prior to taxes, while services price starts at 11 euro cents with the consumer at 13 Eurocents, there are some other numbers about 6-7 for households but that's a subsidy from the Government and you won't qualify by running 10 3kw miners.
Also, do not lump all nordic countries into the same model, while Norway might indeed have a lot of hydropower, in both Sweden and Finland nuclear is the main producer of electricity, hydro in Finland for example is just 1/6 of the total.
Anyhow, I think that OP just looked over some figures, saw a yearly average of industrial prices at 7 eurocents per kWh and thought why not, then, reality kicked in and saw what the real prices are including VAT, so, back to square one. Trying to set up a mining business in Europe without some solid connections that might be able to grant you a two-year contract on some below-market prices in an already cheap country it's just business suicide right now.
