The pumped storage plants are used to store hydro electrical energy. This scheme has an upper and lower reservoir. During peak power generation, electrical energy is used to pump water from the lower reservoir to the upper reservoir. During peak load period, energy in the upper reservoir is used to generate the power.

The western region of India with steep gradients of rivers has the largest potential for the development of pumped storage plants. A potential of 96,524 MW was identified by CEA during studies conducted in 1978–1987.

Name of the station	State	Installed capacity (MW)
Srisailam LBPH	Telangana	900
Purulia PSS	West Bengal	900
Kadamparai	Tamil Nadu	400
Ghatghar	Maharashtra	250
Bhira	Maharashtra	150

Synchronous machines in these plants can be made to act as synchronous condensers for voltage support. It helps in the straightening of load curve by act load during low load period and as generating source during peak periods which improves the overall economy of power system operation.
