Tennessee Valley Authority’s Wind Turbines

TVA manages a total of 18 wind turbines on Buffalo Mountain in Anderson County at Wind Rock Park.

Originally begun with three turbines built in 2000, the project was expanded to its present capacity with the addition of 15 turbines in 2004. The wind turbines are located along a two-mile stretch of ridgeline to intercept the wind and together produce about 29 megawatts of electricity, or enough to power 3,750 homes.

The newer turbines stand approximately 260 feet tall, with blades that span 135 feet, and can be seen from many miles away. The turbines are capable of producing their maximum output of electricity when wind speeds are 10-25 miles per hour. —WB
