Hydroelectric

Hydroelectric power is the most clean, reliable, efficient and economical of all renewable energy sources. And thanks to the Tennessee River system, we have plenty of it in our region. It supports our mission of providing clean, reliable and affordable electricity to the people and businesses of the Tennessee Valley.

TVA's hydroelectric system consists of:

  • 29 power-generating dams throughout the Tennessee River system, some of which date back to the TVA’s early days in the 1930s.
  • A pumped-storage plant near Chattanooga called Raccoon Mountain.
  • Four Alcoa dams on the Little Tennessee River.
  • Eight U.S. Army Corps of Engineers dams on the Cumberland River.

The hydroelectric dams and their reservoirs provide additional benefits to our region, including flood control, river navigation and popular recreational opportunities—all while minimizing effects on our environment. Learn more about how hydroelectric power works.

The pumped storage plant at Raccoon Mountain is a prime example of the recreation opportunities and minimal environmental impact of hydroelectric power. It produces 1,650 megawatts of power and yet the water and surrounding woods are tranquil enough to be designated a state wildlife observation area that’s home to whitetail deer, woodchucks, gray foxes, bald eagles and raccoons.
