Nonsense. France became a net importer last year [1] because of faulty pipes in a quarter of their plants, and the problems are continuing this year [2]. Their output has been low this year again [3].
My understanding is that that over the period of 2015-2022 Germany has imported anywhere from 2-8 TWh per year from France, which is up to 1.5% of total annual power draw. [1] I don't know if you consider that significant or not.
While the generation is fairly constant, if there is an excess of power (which there historically has been) then you can import a variable portion based on the European grid and electricity market pricing right?
At the same time Germany was exporting to other countries and was overall one of the largest exporters of electricity in Europe. Even France imported from Germany, but overall France exported more.
What people sometimes like to do is take a snapshot at a certain date and time and try to make a broader point, but overall Germany has been a net exporter of electricity for years and years in a row.
