A quick web search indicates the capacity of the two coal plants in question are 2933 and 1300 Megawatts, respectively. It will be economically impossible to replace those plants with wind and solar - the high cost of grid improvements, massive back-up capacity needed, low energy density, and limited productive life of windmills and solar panels make it so.
That means they’ll have to go to natural gas which requires more pipelines which the environmentalists don’t like either. Getting new pipelines through the permitting and ensuing lawsuits is not exactly impossible. The issue is how drawn out the process is.
Replacing the two power plants would require at least eight of GE’s biggest combustion turbines.
