In Summary

  • Central Electricity Authority (CEA) report highlights Pumped-Storage Projects (PSPs) crucial for India's clean energy transition and grid stability.
  • India has 7 GW installed PSP capacity, with a potential of 267 GW (58 GW on-stream, 209 GW off-stream).
  • PSPs function as large-scale batteries, storing surplus renewable energy and generating power during peak demand.

In Summary

Central Electricity Authority (CEA) in a new report has recognized the critical role of PSPs in India’s clean energy transition, ensuring grid stability and meeting long-duration energy storage.

About Hydro Pumped-Storage Projects (PSPs)

  • Hydroelectric energy storage system that uses two reservoirs at different elevations to store electricity by pumping water upward during periods of surplus renewable generation.
    • Generates power during peak demand by releasing stored water downward through turbines, acting like a large-scale battery.
  • Potential and Status: India’s currently installed hydro pumped-storage capacity stands at about 7 GW.
    • Presently, India’s pumped storage potential is about 267 GW, which includes 58 GW of on-stream PSPs and 209 GW of off-stream PSPs.
  • Types:
    •  Open-loop: Connected to a natural water body (river/lake)
    • Closed-loop: No connection to natural water bodies, uses artificial reservoirs only.

Off-stream PSPs

Pumped Storage Projects that do not have a connection to natural water bodies, relying solely on artificial reservoirs for water storage.

On-stream PSPs

Pumped Storage Projects that are connected to or utilize a natural water body, such as a river or lake, as one of their reservoirs.

Central Electricity Authority (CEA)

A statutory body constituted under the Electricity (Supply) Act, 1948, responsible for technical, economic, and commercial aspects of electricity systems in India. It advises the government on policy and planning.
