Also critically they don’t have to build these coal plant to be economically used in the same way as free market states do. They’re building them mostly as a hedge - if they end up barely used , which is likely given renewable trends, that’s ok for state owned power. It makes everything a bit more expensive, but you can’t exactly vote for an alternative. If they need to get used a lot for whatever reason, no one is unhappy either, you avoid shortages and discontent. Whereas coal stopped being built in market economies roughly as soon as it became uneconomical.
