Can India's Power Sector Stay Resilient If El Niño Reduces Hydropower Output?
India's Power Ministry is preparing a comprehensive contingency strategy to ensure uninterrupted electricity supply if El Niño leads to weaker rainfall and lower hydropower generation. The plan follows directions from the Prime Minister, who asked ministries to prepare mitigation strategies for the possible economic impact of El Niño.
With electricity demand typically peaking during August and September, the government is exploring multiple options to bridge any supply gap and maintain grid stability.
Key Developments
✔ Power Ministry has prepared a contingency plan to offset lower hydropower generation.
✔ India's installed large hydropower capacity stood at 51.41 GW as of 31 March 2026.
✔ Grid India has reached out to wind power developers to maximise renewable generation.
✔ Central Electricity Authority is preparing measures to prevent electricity shortages during August and September.
✔ The government is evaluating the restart of NTPC's gas-based power plants.
✔ Around 5,000–8,000 MW of gas-based generation capacity could be utilised once gas supplies improve.
✔ CREA estimates El Niño could create an electricity demand-supply gap of nearly 18 TWh.

Sectors That Could Remain in Focus
| Segment | Potential Impact |
|---|---|
| Hydropower | Lower rainfall may reduce electricity generation. |
| Gas-Based Power | Higher plant utilisation if fuel availability improves. |
| Wind Energy | Generation may be maximised to support the grid. |
| Power Utilities | May benefit from higher electricity demand and improved capacity utilisation. |
The government's proactive planning highlights its focus on ensuring energy security during a potentially challenging monsoon season. Increased utilisation of gas-based plants, renewable energy and improved grid management could help reduce the impact of weaker hydropower generation. However, the actual effect will depend on rainfall patterns, fuel availability, electricity demand growth and weather conditions over the coming months.
