India’s green transition is missing long-duration energy storage
India’s power transition needs affordable long-duration energy storage to balance intermittent solar and wind supply with rising electricity demand.

Key takeaways
- Pumped hydro storage remains a recognised option for balancing electricity supply and demand across longer periods.
- Compressed air energy storage is one of the storage technologies mentioned for India’s future energy mix.
- Solar and wind power are variable sources and require balancing resources when output does not match demand.
India’s renewable-energy expansion is increasingly constrained by a basic systems problem: solar and wind power are intermittent, while electricity demand can rise when generation is low. Long-duration energy storage is needed to move power across hours, not just minutes, if the clean-power transition is to remain reliable and affordable.
The UPSC angle

How UPSC may frame India’s energy-storage challenge
UPSC may ask how India can integrate intermittent renewable energy with grid stability, compare storage technologies, or discuss policy and infrastructure gaps in the clean-energy transition.
