Figure: Pumped storage plant. Pumped storage plants are employed at the places where the quantity of water available for power generation is inadequate. Here the water passing through the turbines is store in 'tail race pond'During. low load periods this water is pumped back to the head reservoir using the extra energy available.
When there's a sudden demand for power, the “head gates” are opened, and water rushes down the tunnels to drive the turbines, which drive the powerful generators. This is called generation cycle. The water then collects in the lower reservoir, ready to be pumped back up later.
