"If I was from Norway or Sweden I would demand the national grid to massively invest into the transmission lines to make all the electricity produced in the country actually usable anywhere in the country. " That would be fine if it was only about prices in the country. But due to the way the EU agreement works, higher capacity transmission lines only means that more electricity will be exported and more of those countries would suffer. Norway currently exports more than the surplus. With higher internal transmission capacity Norway would export even more. Which will have to be imported from EU comes winter, at prices which have already closed a LOT of businesses in Norway.
