> I'm forced to pay the highest spot price in the EU

This isn't true — prices are the same throughout a zone, but Germany and Sweden are not in the same zone. Sweden has several zones. The total possibly export from Sweden to neighbouring countries is not unlimited, which is the reason for the boundaries.

I have a layman understanding of the pricing structure so it's probably not entirely true "paying the highest spot price in the EU" directly but given I was paying 5-10x more for electricity in December 2022 than ever before my best guess is that when Germany was paying a lot more for electricity due to an increase in the price of gas-generated electricity we were affected by the dominoes falling: electricity would be sold for a higher bid if exported to Germany (or to a zone neighbouring Germany which would be selling to Germany) which caused a shortfall in my zone (SE3) increasing the bid price.

So even if it was a second order effect I had to pay much more than ever before due to increased spot prices in other zones.
