Since you couldn’t be arsed to check for yourself before throwing out baseless accusations, here’s a translation of a relevant part from the linked article. I doubt you’ll read it, but it’ll be here for anyone else that stumbles across this thread.
The past winter was at times dramatic, for example when several nuclear power reactors were shut down for repairs. But thanks to the fact that mainly households had previously reduced consumption clearly in step with the rampant electricity prices, Sweden managed to maintain the power balance even in the worst hour, the so-called peak load hour.
“But if we had maintained the consumption, we would have had to cut down.”, says Lowina Lundström, Division Manager Systems at Svenska kraftnät.
The electricity had not been enough
At that time, the import would not have been enough to cover the electricity demand during the peak load hour on December 16, 2022, between 09:00 and 10:00. The import was then at a maximum of 3,290 MW, approximately equivalent to three nuclear power reactors, which was the highest level to date.
