Yup.. Happens to align somewhat with climate goals too, luckily for the rest of us. Once solar+batteries becomes the cheapest form of generation, the coal usage should also drop, if that isn't already the case

Marginal versus bulk. It can make sense, economically, to keep building coal plants even if solar is cheaper if you’re building solar as fast as you can and still need more power.
