Coal-fired plants have formed the backbone of our power system since TVA first started using them in the 1950s. However, in keeping with our commitment to generate safer, cleaner energy, we’re beginning to retire older, less efficient coal-fired plants and replacing them with low- or zero-emission electricity sources including:
TVA’s five active coal-fired fossil plants have a total of 25 generating units. Each unit produces electricity by burning coal in a boiler to heat water to produce steam. The steam, under tremendous pressure, flows into a turbine, which spins a generator to produce electricity. The steam is cooled, condensed back into water, and returned to the boiler to start the process over.

There's no getting around it: Burning coal creates ash. But that doesn't mean ash has to go to waste. Dry ash can be repurposed in building materials, abrasives, cement and more. Learn more about how coal ash is recycled and reused.
