Coal generation in the US was down about 29% in Q1 2023 according to EIAs Electric Power Monthly.
A more interesting story to me is what happens on the state level. In particular, I like the stories in:
Georgia - where coal generation was down 48% Y-Y, even before new Vogtle nuclear unit was added to the grid.
Oklahoma - where coal generation was down 74% and the capacity factor for remaining coal plants was 10%..
