Both users and companies could be incentivized to lower their consumption of electricity by increasing the price astronomical during periods of scarcity. A minimum of 1 Ampere per household without surcharge and beyond that enough to pay off the infrastructure. Taking a sauna or charging your car during peak times would costs, let’s say, €500. Assuming that in the north of Sweden there is ample Hydro energy, in the north the surcharge would be lower than in the south.

I strongly believe people and organizations would accommodate, just like during winter times in the north of Sweden one wears a different coat than in the south. But with the current system one isn’t incentivized to adapt power consumption to cost and hence more & more costs are made to build power lines from the north to feed the south of Sweden. And the same for standby fossil fuel plants.

Also prepaid electricity bills with automatic cutoff when exceeding, remaining 1 Ampere. Similar to the days when homes/tents would be heated by burning wood, during summertime one needs to collect enough firewood for the whole winter. Different times but in concept nothing new.
