Europe is scrambling to expand its electricity network, which doesn't have enough capacity. I don't know how badly Sweden and Denmark are affected, but in e.g. the Netherlands it inhibits the move away from fossil fuel for both homes and companies, and even disrupts building developments. So, anything that delays this for unexpected reasons is news. Is it interesting enough for HN? That's for you to decide.

Sweden is very well positioned due to well developed hydro, but when germany was forced to give up russian gas, more electricity was exported, causing record high prices.

Interestingly, the hydro plants are located in the north and the national power grid is not dimensioned for massive export, so the export to germany from the south of sweden caused a strong price gradient.
