Careful, the renationalization is due to a lot of factors, the main one is that the EU forced EDF to sell its nuclear eneegy at a loss to private energy providerd in order to "free the market". Look for ARENH if you would like to learn more (quick Google https://www.nusconsulting.com/energy-blog/arenh-reform-could...)

I didn't mean to imply that nationalization happened because nuclear power isn't commercially viable. The French situation was special even before full nationalization.

I really doubt ARENH is the problem because as far as I understand it, it only applies to EDF's existing nuclear power plants. At 42 EUR/MWh wholesale, those plants should still make a tidy profit. Apparently, too few of them were actually running last year, and the French government imposed further price restrictions that also affected resale of energy that EDF purchased elsewhere at market prices (not coming from EDF's own nuclear fleet or its other power plants).

Electricity generation in the US isn't "under strong government influence"?

I wasn't talking about regulation. EDF's relationship with the French government goes well beyond that.
