When looking at live data we should keep in mind that currently 14 reactors are stopped in France for various reasons (maintenance delayed to winter season due to COVID, safety measures of several reactors due to investigation in a deterioration of a comportent in one).

In normal circumstances France should be exporting to Germany right now (it would make no economical sense for German grid operators to use the very expensive gas if neighbors could deliver lower cost indigenous production). Sadly right now France can't deliver and it increases tension even more on gas demand.

Thanks to it's nuclear power, France is the first electricity exporter in the world, Germany is a close second.
