It's really not a bold claim. It may seems like so if you chose to believe in the idealized market model but that does not exist in real life.
As for the references, I linked to them (it's in French however) in another comment here.
Also, all of the progress and innovations and building of new generations and renewables and everything until recently has been done without a market, at least in France, which probably has one of the best electricity system in the world.
