Coal isn't cheap. Specifically coal powerplants are not and it's got nothing to do with emissions. One of the pinch points in the Australian power grid has actually been that a bunch of coal plants are aging out and no private enterprise wants to even bother financing their replacement because it's a money loser compared to renewables build out.

Fortunately this is well on it's way to being solved by the massive battery build out which has happened which means evening peak electricity usage has declined enormously[1] - i.e the primary "sun not shining" point of the day is rapidly turning into an energy use low point for the grid (which makes sense: business powers down, people go home and their batteries which have been charging cover cooking - I have an induction cook top and a 10kw inverter covers everything).
