It doesn't matter if it went up or stayed the same (or even went down). Coal consumption would have gone down even faster if the nuclear plants stayed open. Closing the plants showed that they were not serious about reducing fossil fuel use, only green virtue signaling.

I think that they are importing much more gas, and that's been very painful, economically, because it was expected to come from Russia... but it hasn't (directly).

I also think that there has been an increase in wind and solar - but Germany isn't in the greatest place for either of these geographically.

The French people are getting a bad deal, having subsidized their nuclear fleet for fifty years it's now being heavily used to provide high cost export electricity to Germany and the UK, meaning that the French grid price is also high despite their probity and sense in building out nuclear.
