Figure 5.5.1 5.5. 1: A general scheme of the Raccoon Mountain Pumped Storage Hydroelectric Plant. It uses dual-action Francis turbines. Details of the turbines and the motors/generators are not shown in the figure, we have to understand that they are all hidden in the unit marked as the "Powerplant Chamber" (source: Wikimedia Commons).

The basic operation principle of a pumped-storage plant is that it converts electrical energy from a grid-interconnected system to hydraulic potential energy (so-called ''charging'') by pumping the water from a lower reservoir to an upper one during the off-peak periods, and then converts it back (''discharging'') by exploiting the available

Instead of pumping water uphill from a low reservoir to a higher one to store energy, as occurs in pumped hydroelectricity, one pumps heat from a cold body to a hot one by means of a heat engine.
