Gallatin Fossil Plant
Balancing efficient power production with environmental protection
Electricity is produced at Gallatins four coal-fired units by heating water in a boiler to produce steam. Under extremely high pressure, the steam flows into a turbine that spins a generator to make electricity. In a typical year, Gallatin generates about 7 billion kilowatt-hours of electricity, enough to supply about 480,000 homes.
Low-cost and cleaner energy
Through 2011, TVA has spent about $5.4 billion on emissions controls at its fossil-fuel plants to help TVA produce power as cleanly as possible.
In support of recent environmental agreements and its vision of being one of the nation’s leading providers of low-cost and cleaner energy by 2020, TVA plans to install selective catalytic reduction systems to reduce nitrogen oxide emissions and scrubbers to reduce sulfur dioxide emissions on all four Gallatin units by Dec. 31, 2017.
TVA added four combustion-turbine units at Gallatin in the early 1970s
and another four in 2000. These units are designed to start quickly and typically are operated only during peak demand periods.
