India’s hydroelectricity output fell on the steepest tempo in not less than 38 years throughout the yr ended March 31, a Reuters evaluation of presidency information confirmed, as erratic rainfall compelled additional dependence on coal-fired energy amid greater demand.
The 16.3% drop in era from India’s largest clear vitality supply coincided with the share of renewables in energy era sliding for the primary time since Prime Minister Narendra Modi made commitments to spice up photo voltaic and wind capability on the United Nations local weather talks at Paris in 2015.ll
Renewables accounted for 11.7% of India’s energy output in the yr that ended in March, down from 11.8% a yr earlier, a Reuters evaluation of day by day load despatch information from the federal grid regulator Grid-India confirmed.
India is the world’s third-largest greenhouse gasoline emitter, and the federal government typically factors to decrease per-capita emissions in comparison with developed nations to defend rising coal use.

A five-year low in reservoir ranges means hydro output will probably stay low throughout the hottest months of April-June, specialists say, doubtlessly boosting dependence on coal throughout a interval of excessive demand earlier than the monsoon begins in June.
Ok.J. Ramesh, former chief of the Indian Meteorological Department, mentioned there’s an elevated likelihood of excessive rainfall throughout the annual monsoon this yr, however any affect on hydropower output wouldn’t be seen earlier than July.
“When hydro increases due to good rainfall, it should be used to reduce dependence on thermal,” he mentioned, including that erratic rainfall means India shouldn’t depend on hydro as a dependable energy supply in the long run.
Hydro’s declining share
Hydropower’s share in India’s whole energy output fell to a file low of 8.3% throughout the fiscal yr ended March 31, Grid-India information confirmed, in contrast with a median of 12.3% in the ten years by means of 2020.
The share of hydropower has steadily declined in current years amid a slowdown in the addition of latest capability, with different sources together with coal, photo voltaic and wind gaining share.
The lightest rainfall since 2018 meant lowered water ranges in reservoirs, pushing annual hydro era to a five-year low of 146 billion kilowatt-hours (kWh).
Meanwhile, energy era from coal and lignite in 2023-24 rose 13.9%, outpacing the 9.7% enhance in renewable sources’ output, information from the grid regulator confirmed. Total energy era rose 10.3% in 2023/24, Grid-India information confirmed.
India missed a 2022 goal to put in 175 gigawatts (GW) of renewable vitality, and stays 38.4 GW in need of that purpose, with Grid-India information exhibiting India’s dependence on fossil gasoline for energy hit a five-year excessive of 77.2% in 2023/24. India’s addition of renewables slowed to a five-year low in 2023.
Globally, the hydropower output fell for less than the fourth time since 2000 as a consequence of decrease rainfall and hotter temperatures caused by the El Nino climate sample, in response to vitality assume tank Ember.
Hydro output in India, the sixth-biggest hydropower producer, fell nearly seven occasions quicker than the worldwide common, Ember information confirmed.
