RESERVOIRS AND POWER PLANTS

Raccoon Mountain Pumped-Storage Plant

The Raccoon Mountain project is TVA’s largest hydro facility. Water is pumped to this mountaintop reservoir and then released to generate electricity when added power is needed by the TVA system.

Raccoon Mountain Pumped Storage Plant is located in southeast Tennessee on a site that overlooks the Tennessee River near Chattanooga.

The plant works like a large storage battery. During periods of low demand, water is pumped from Nickajack Reservoir at the base of the mountain to the reservoir built at the top. It takes 28 hours to fill the upper reservoir. When demand is high, water is released via a tunnel drilled through the center of the mountain to drive generators in the mountain’s underground power plant.

The area around Raccoon Mountain is a state-designated Wildlife Observation Area. The mountaintop is home to whitetail deer, woodchucks, gray foxes, and, of course, raccoons. The most compelling wildlife attraction of the area is a large wintering population of bald eagles, which can be sighted from the overlook as they hunt in the woods and waters.

The Raccoon Mountain Visitor Center was reopened to the public on June 7, 2003. It is open from 9 a.m. to 5 p.m. daily except major holidays. Tours are no longer available of the power plant itself, but the center has photographs and models to give visitors the same sort of experience. TVA will continue to close all visitor centers when the Homeland Security alert is at a level of high (orange) or higher.
