Colbert Fossil Plant

Colbert Fossil Plant is located on TVA’s Pickwick Reservoir on the Tennessee River in Alabama. The plant is named after George Colbert, a chief of the Chickasaw Indian Nation in the early 19th century.

Balancing efficient power production with environmental protection

Electricity is produced at Colbert’s five 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. Colbert generates some 7 billion kilowatt-hours of electricity a year, enough to supply 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, consistent with efficiency. This includes installation of a selective catalytic reduction system at Colbert Unit 5 to reduce nitrogen oxide emissions by about 90 percent.

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, Colbert Unit 5, by Dec. 31, 2015, and Colberts 1-4, by June 30, 2016, will be:

  • Removed from service
  • Converted to renewable biomass
  • Controled by adding a scrubber for sulfur dioxide reduction, or retired.

If the units are removed from service by these dates, they could be returned to service with emissions controls within three years.

Combustion turbines

TVA added eight combustion-turbine units at Colbert in the early 1970s. These units are designed to start quickly and typically are operated only during peak demand periods.

Toxics Release Inventory

TVA is required to report annually to the Environmental Protection Agency on the amounts of chemicals released by its fossil-fuel plants. Check here for the latest data on Colbert.

Emissions Data

TVA monitors other emissions at its fossil plants, including SO2, NOX, CO2, and mercury. Check here for the latest data on Colbert.
