The stuff with FERC & DOE is a little more complex. Nobody likes coal, and the north American electricity market mechanisms have had prices for years that are too low for coal to turn a profit. Great, the market has spoken you say? The only problem is it presents a major issue for national security if all you have is natural gas and some renewable. What happens if the pipelines freeze? Grid resiliency means having a diverse enough fuel mix to still be ok if we have certain disasters. One day we'll hopefully have very large and affordable batteries and a lot more renewables, but despite huge growth in this sector, most demand is still sourced from unclean fossil fuels today. Nobody (except Perry) is really expecting or wanting coal to make a comeback. They're just trying to provide a market mechanism to compensate power companies to keep just enough coal online so we can better hedge against blackouts.
