France has to 48 npps hitting 40 years this decade or well they already have and has a single plant under construction with massive cost overruns and delays.

I am aware. There are no plans to shut all of them down anytime soon, though.

2022 was at 48.5% even with nuclear still running. https://www.energy-charts.info/charts/energy_pie/chart.htm?l=de&c=DE&source=total&interval=year&year=2022

2023 is at 46.2% so far, and I doubt it will get better during autumn and winter. https://www.energy-charts.info/charts/energy_pie/chart.htm?l=de&c=DE&source=total&interval=year&year=2023
