It's hard to miss the TVA Pumped Storage Plant. It is a hydroelectric facility built between 1970 and 1978 that serves as a storage tank, where, when water demand is low, water is pumped into the reservoir on top of Raccoon Mountain from Nickajack Lake (part of the Tennessee River) below. Then, when water demand peaks, the reverse occurs... water is released through a tunnel that was drilled down through the center of Raccoon Mountain. The water drives several huge generators inside Raccoon Mountain.
|Pretty big stuff.|
This storage plant was closed from 2012 to 2014 for some $90 million in repairs as a precaution because of cracks in the rotors inside the generators' magnetic field. Similar issues caused a catastrophic failure in 2009 at a pumped storage plant in Austria.
Fixing the rotors at Raccoon Mountain cost taxpayers $55 million. While the plant was down, TVA installed a 500,000-pound power transformer bringing the total repair bill to $90 million.
