Germany is about to spend over 600bn for grid expansion till 2045 and EEG subsidies for the next 10 years will too, be about 200bn (if not cancelled by govt which is unlikely unless AFD is elected)
France downscaled ren deployment plans while pushing for 6 new EPR2's + another 8 if there aren't major delays.
So not only France needs to spend/subsidize less in this period - it'll also still have cleaner grid and lower household prices than Germany in parallel
