India continued to strengthen its clean energy journey in 2025, with renewable power becoming an increasingly reliable part of the country’s electricity supply. During December 2025, India generated 23,331.39 million units (MU) of electricity from renewable sources, excluding large hydro projects. This marked a year-on-year increase of 17.99 percent compared to December 2024, showing steady growth across renewable technologies. More importantly, the annual power generation numbers for 2025 highlighted how renewables are now playing a major role in meeting India’s electricity demand.
For the full year 2025, India’s total renewable power generation reached 297,802.56 MU. Solar energy emerged as the largest contributor on an annual basis, generating 164,542.97 MU during the year. This strong performance underlines the rapid expansion of solar capacity across the country and its growing importance in India’s energy mix. Large-scale solar parks, rooftop installations, and open-access solar projects have all contributed to this rise, supported by favorable government policies and private sector participation.
Wind power also played a crucial role in annual renewable generation. In 2025, wind energy generated 104,006.54 MU of electricity. While wind generation is more seasonal and depends on weather conditions, it remained a key pillar of India’s clean energy system. By the end of December 2025, India’s total installed wind capacity stood at 54,510.93 megawatts, reflecting continued investment in wind projects, especially in wind-rich states.
Looking at monthly performance, solar power remained the biggest contributor in December 2025. Solar plants generated 14,946.83 MU during the month, accounting for 64.06 percent of total renewable generation. This was 39.60 percent higher than solar generation in December 2024, highlighting strong year-on-year growth. Wind energy followed, producing 4,483.33 MU in December, or 21.47 percent of the renewable total for the month. Other renewable sources such as biomass, bagasse, and small hydro together contributed 14.47 percent, adding diversity and stability to the energy mix.
Overall, solar and wind together accounted for 85.53 percent of renewable electricity generated in December 2025, reflecting their dominance in India’s renewable sector. The strong annual and monthly generation figures show that renewable energy is no longer a marginal contributor but a core part of India’s power system. Going forward, experts believe that expanding energy storage, strengthening grid infrastructure, and improving access to financing will be essential to support higher renewable generation as India moves toward its target of 500 gigawatts of renewable capacity by 2030.
