India Generates 21,488 Million Units Of Renewable Power As Solar Leads October 2025 Growth

India recorded a significant achievement in its renewable energy efforts in October 2025 when the country generated 21,488.49 million units of electricity from renewable sources, excluding large hydro projects. Solar energy made the biggest contribution, supplying 13,063.14 million units and accounting for 60.79 percent of the total renewable electricity generated during the month. This output was slightly higher than September 2025 and showed a strong year-on-year increase of 6.58 percent compared to October 2024. The steady rise in solar electricity generation highlights how central solar power has become to India’s clean energy strategy. Together, solar and wind supplied 90.60 percent of all renewable electricity generated in October, making them the main drivers of the sector.

The increase in solar output has been supported by a range of government policies, including financial assistance schemes that encourage capacity addition and technological improvements in photovoltaic systems. The addition of new solar projects and better efficiency levels has helped increase total solar generation across the country. Both public and private sector participation have played important roles in this expansion. Despite temporary challenges caused by seasonal factors like monsoon clouds, solar has proven to be a consistent and fast-growing renewable energy source that continues to strengthen month after month.

Wind energy also made a major contribution in October 2025, though its share was smaller than solar. Wind farms generated 6,406.49 million units of electricity, which accounted for 29.81 percent of the total renewable electricity generated during the month. Wind output was supported by moderate to strong wind speeds and remained the second-largest contributor after solar. By the end of October 2025, India’s total installed wind capacity had reached 53,599.9 megawatts. While wind energy is seasonal in nature and often depends on weather patterns, months like August provide higher wind speeds that help balance the overall renewable mix. Experts point out that improved forecasting tools and stronger support systems are needed to ensure stable and reliable wind power output.

Other renewable sources, such as biomass, bagasse, and small hydro, together contributed 9.4 percent of the total renewable energy generated in October. Although their share is smaller compared to wind and solar, these sources provide essential diversity to India’s renewable energy mix and help reduce dependence on the two main technologies.

Overall, India’s renewable electricity generation in October 2025 was 21.39 percent higher than the generation recorded in October 2024. Solar output also increased compared to August, showing a steady upward trend. As the country moves forward, it will need to strengthen energy storage systems, modernize its power grid infrastructure, and expand financing opportunities to meet its target of installing 500 gigawatts of renewable energy capacity by 2030. With solar and wind together contributing more than 91 percent of renewable generation in October, their role will remain central in shaping India’s future energy transition.
