A major 1,200 MW Pumped Storage Hydropower (PSH) project was recently approved by the Uttar Pradesh government in Sonbhadra.
- Central Electricity Authority has estimated the on-river PSH potential in India to be about 103 GW.
About Pumped Storage Hydropower:
- Type: Hydroelectric energy storage
- Principle: Utilizes gravity to generate electricity
- Structure: Two reservoirs at different elevations
Processes:
- Recharge: Water is pumped from the lower to the upper reservoir during surplus electricity production.
- Discharge: During peak energy demands, water flows downwards, passing through turbines to generate electricity.
Types of PSH:
- Open-loop PSH: Connected to a natural water body.
- Closed-loop PSH: Not connected to any external water body.

Frequently Asked Question:
What is Pumped Storage Hydropower (PSH) and how does it work?
Pumped Storage Hydropower uses gravity to generate electricity with 2 reservoirs at different elevations. During surplus electricity production, water is pumped from lower to upper reservoir for storage. When energy demand peaks, water moves down and passes through a turbine to produce instant electricity.
What are the two types of Pumped Storage Hydropower?
Pumped Storage Hydropower has two types – Open-loop PSH, which is connected to a natural water body, and Closed-loop PSH, which is not connected to an outside body of water.
What is the estimated PSH potential in India according to Central Electricity Authority?
The Central Electricity Authority has estimated the on-river PSH potential in India to be about 103 GW.
How does Pumped Storage Hydropower help in balancing the electricity grid?
Pumped Storage Hydropower helps in balancing the electricity grid by storing excess electricity when demand is low and releasing it when demand is high, thus providing a reliable source of instant energy.
What are the key benefits of Pumped Storage Hydropower projects?
Pumped Storage Hydropower projects provide energy storage, grid stability, peak load capacity, and more efficient utilization of existing resources, helping in meeting energy demands effectively.
