How much energy storage capacity does the Central Electricity Authority project India will need by 2031-32?
- A.73.93 GW
- B.26.69 GW
- C.47.24 GW
- D.100.81 GW
Correct answer
Explanation
The correct answer is 73.93 GW. As solar and wind capacity grows, electricity has to be stored when generation runs ahead of demand and returned when it falls short, so the Central Electricity Authority projects a storage requirement of that size by 2031-32. Option B, 26.69 GW, is only the pumped storage share within that projection, and option C, 47.24 GW, is only the battery energy storage share; the two together make up the answer. Option D belongs to a different count altogether: 100.81 GW is the pumped storage capacity the CEA roadmap expects to be commissioned by 2035-36, which would carry cumulative pumped storage capacity to 105.56 GW. Batteries answer short-duration needs, while pumped storage supplies long-duration and peaking support.

- A.Southern Region
- B.Northern Region
- C.Western Region
- D.Eastern Region
Show answer
The Central Electricity Authority credits that lead to the landform of the region and the steep gradients of rivers that rise in the Western Ghats, which give engineers the height difference a pumped storage scheme needs.
