The amount of coal received by power plants in the United States has largely declined over the past decade as coalfired electricity generation has fallen and many coalfired power plants have closed. However, slightly more coal was shipped to power plants in 2022 than in 2021 even though coalfired generation fell by nearly 8% in 2022.
Mining coal. Coal miners use large machines to remove coal from the earth. Many coal deposits, called coal beds or seams, are near the earth's surface, but others are deep mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.
A coalfired power station is a type of fossil fuel power station. The coal is usually pulverized and then burned in a pulverized coalfired boiler. The furnace heat converts boiler water to steam, which is then used to spin turbines that turn generators.
Coalfired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into the water, and returned to the boiler to start the process over.
§Prior to the fracking revolution, PJM coal plants ran at 60% 70% capacity factors oPower companies signed longterm coal contracts at high levels with confidence they would burn the coal §Since 2015, coal plants have run at 30% 50% capacity factors on average oMany coal plants are dispatched after gas CCGT plants and are run for reliability
Today, the entire coal industry—including mines and power plants—employs roughly 160,000 people. For scale, the solar industry provides 374,000 jobs in the US, with most of those people—261,000—working on solar at least half time. If you're a coal miner, or live in a mining community, the transition has been hard.

by Chris Woodford. Last updated: September 19, 2023. Not so long ago, alchemists dreamed of turning cheap and ugly metals into valuable ones like gold. Power plants (also called power stations) pull off a similar trick, converting lumps of coal and drops of oil into zaps of electric current that can cook your dinner or charge your phone.
characteristics, and the assignment of coals to power plants. The second topic is the coal supply curves which were developed for EPA Platform v6 and the bottomup, minebased approach used to develop curves that would depict the coal choices and associated prices that power plants will face over the modeling time horizon.
Coal is primarily used as fuel to generate electric power in the United States. In coalfired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into highpressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in the United States was ...
