Key Highlights

  • Hydroelectric generation in India fell almost 21% year-on-year in 2024, the steepest decline since February.
  • The drop stems from El Niño-driven dry conditions reducing water flow to dams and reservoirs.
  • Reduced hydropower output forces grid operators to rely more on costlier thermal and imported coal.
  • Utilities and energy-intensive industries face higher operational costs amid constrained supply.

India’s hydroelectric power generation has slumped nearly 21% from a year earlier, the sharpest decline in 2024, as El Niño-induced drought drains reservoirs and strains the national power grid. The shortfall is forcing grid operators to lean on pricier thermal plants and imported coal, lifting energy costs for utilities and industrial consumers.

What Happened

Hydroelectric plants across India produced almost 21% less electricity in 2024 compared to the same period last year, according to government data. The drop marks the largest year-on-year contraction since February and reflects prolonged dry spells linked to the El Niño weather pattern.

Market Impact

The hydropower deficit is tightening India’s electricity supply, pushing grid operators to ramp up coal-fired generation and increase fuel imports. Thermal plants, already the dominant power source, are running at higher capacity, lifting spot coal prices and widening the cost gap between renewable and fossil-based energy.

What's Next

Analysts expect hydropower output to remain subdued through the monsoon season if El Niño conditions persist. Grid operators may extend reliance on thermal plants and accelerate solar and wind capacity additions to offset the shortfall. The government could also introduce temporary tariff adjustments or demand-side measures to ease pressure on the power grid during peak summer months.
