I would suggest reading up on the difference between the household and wholesale electricity market. German households pay among the most expensive electricity in the EU while the commercial wholesale market is at the lower end.
The difference comes from taxes and fees.
Germany briefly hit 45 cents/kWh last year due to the war. We are getting back to normal and in March the average price was 10 cents/kWh.
In other words, even during the tail ends of winter and war induced supply crunches the average price was too low to support nuclear.
New built nuclear is having energy crisis prices all year around.
