As of 30 September 2025, India’s total installed electricity capacity crossed 500 GW and reached 500.89 GW. Within this total, non-fossil fuel sources accounted for 256.09 GW, or more than 51% of installed capacity, while fossil-fuel-based sources accounted for 244.80 GW. For exam preparation, the core point is that India achieved the target of having 50% of installed electric power capacity from non-fossil sources five years before the 2030 timeline. India had also crossed the 250 GW milestone in non-fossil power capacity in August 2025.
This development is not only an environment update. It connects Indian Economy, Science and Technology, climate policy, energy security and infrastructure. The capacity mix shows the rising role of solar, wind, hydro and nuclear power in India’s electricity system. The available figures place solar power capacity at 127.33 GW and wind power capacity at 53.12 GW. During FY 2025-26, from April to September 2025, India added 28 GW of non-fossil capacity and 5.1 GW of fossil-fuel capacity.
The static-GK linkage is with energy resources, the power sector, climate commitments, the Paris Agreement, renewable energy and sustainable development. In prelims, likely facts include total installed capacity, the non-fossil share, the 250 GW non-fossil milestone and the 50% target. In mains, this can be used as an example for energy transition, balancing development with environmental commitments, grid reliability and employment opportunities. On 29 July 2025, renewables met 51.5% of total electricity demand of 203 GW, making it a useful indicator of the growing role of clean sources in power generation.
