This is a list of the 220 operational coalfired power stations in the United States. Coal generated 23% of electricity in the United States in 2021, [1] an amount similar to that from renewable energy or nuclear power, [2] [3] but about half of that generated by natural gas plants. Coal was 19% of generating capacity. [4]
