India’s renewable power generation from solar, wind, hydro and bioenergy rose by a record 98 TWh (+24%) in 2025, driven by strong growth in solar and wind, according to a report by Ember. The increase was twice the nation’s electricity demand growth of 49 TWh, which was abnormally low owing to milder temperatures and slower industrial activity. As a result, India’s fossil power generation fell by 3.3%.

India’s renewable power generation from solar, wind, hydro and bioenergy rose by a record 98 TWh (+24%) in 2025, driven by strong growth in solar and wind, according to a report by Ember. The increase was twice the nation’s electricity demand growth of 49 TWh, which was abnormally low owing to milder temperatures and slower industrial activity. As a result, India’s fossil power generation fell by 3.3%.
Solar and wind both set new individual records for year-on-year increases in 2025, rising by 53 TWh (+37%) and 22 TWh (+28%), respectively. Distributed solar, such as rooftop PV installations, added an estimated 22 TWh in 2025.
India’s share of wind and solar in electricity generation (14%) still lags behind the global average (17%). Yet, wind and solar’s share increased by 3 percentage points in 2025, highlighting the growing importance of clean energy in India’s electricity system.
India is at the forefront of solar electricity growth
India recorded the world’s third-largest increase in solar generation in 2025, adding 53 TWh. The rise in solar generation was driven by a record 38 GW(AC) increase in capacity, higher than the United States (35 GW(AC)) for the first time. The growth in solar power alone was enough to meet the rise in India’s electricity demand in 2025.
Solar also overtook hydro to become India’s largest source of clean electricity, with its share reaching 9.4% in 2025. Output from solar has doubled since 2022, from 96 TWh to 196 TWh in 2025, solidifying India’s position as the third-largest solar generator globally, with nearly double the generation of Japan in fourth place (101 TWh).
“Solar power is the dominant driver of change in India’s power system,” said Aditya Lolla, Ember’s Managing Director. “Along with battery storage, solar is opening a path to fast-scaling, round-the-clock clean power that can enhance India’s energy security and fend off global shocks.”
Ember’s seventh annual Global Electricity Review provides the first comprehensive overview of the global power system in 2025 based on country-level data. It is published alongside an open dataset covering 91 countries representing 93% of global electricity demand, as well as historical data for 215 countries.
“India’s power system is entering a new phase of its transition, driven by record additions in solar and wind capacity in 2025. Going forward, investments in grid infrastructure and flexibility resources will be critical. India is on the right track—auction designs are already evolving to include greater energy storage components. As these projects begin to scale, they will enable more efficient utilisation of low-cost clean power across the system,” says Duttatreya Das, Energy Analyst-Asia, Ember.
