For all of 2024, our estimated cost of natural gasfired electricity averages 32/MWh compared with an average 29/MWh for coal. We expect these similar costs will keep the share of generation from coal near 15% on average in 2024. Coal inventories. We forecast that coal inventories held by the electric power sector will reach almost 150 ...
