#67 Hiwassee Dam Unit 2 Reversible Pump-Turbine


First integrated pump-turbine to be installed in a US power plant and also the largest and most powerful in the mid-20th century

The integration of pump and turbine was the first of many to be installed in power-plant systems in the United States. It was the largest and most powerful in the world. As a "pump storage" unit in the Tennessee Valley Authority's system, it effected significant economies in the generation of electrical energy. The unit was designed by engineers of the Tennessee Valley Authority and the Allis-Chalmers Company. It was built by Allis-Chalmers.
