The TVA Raccoon Mountain Plant is a four unit pumped-storage plant located on the Tennessee River, Nickajack Reservoir, in Marion County, Tennessee, six miles (3.7 km) west of Chattanooga, Tennessee. The four units went into commercial operation between January 31, 1978 and August 31, 19179. Each unit has a generating rating of 392 MW at a 1020 ft head (310.9 meters). Each turbine is a reversible Francis type, with vertical shaft, manufactured by Allis-Chalmers (now Voith Hydro, Inc.). The runner diameter is 16 ft 7 inches (5.05 meters). the runner material is ASTM A296-CA6NM
