TVA - How a Coal Plant Works
Coal-fired 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 water and returned to the boiler to start the process over.

What is the efficiency of different types of power plants
Net generation is the amount of electricity a power plant (or generator) supplies to the power transmission line connected to the power plant. Net generation accounts for all the electricity that the power plant consumes to operate the generator(s) and other equipment, such as fuel feeding systems, boiler water pumps, cooling equipment, and pollution control devices.

Most coal plants in the United States were built before
Most coal-fired capacity (88%) was built between 1950 and 1990, and the capacity-weighted average age of operating coal facilities is 39 years. About half of the coal capacity operating in 2016 use bituminous coal as their main energy source, a type of coal that comes from Appalachian states such as West Virginia, Kentucky, and Pennsylvania.
