Coal state senators have blocked any effort at replacing it.

Switch that power plant to solid oxide fuel cell/turbine running on biogas from waste.  Plenty of that from bribery business as usual in the US government.  All the wasted food alone from 500 dollar lobbyist  funded lunches would do it.

And put a floating wind/wave power installation offshore to provide most off the power the coal used to.

That would be radical.
