India’s installed power capacity reached 513.7 GW in December 2025, driven by strong growth in solar and wind, while thermal power continues to anchor the national grid.
India’s total installed electricity generation capacity stood at 513.73 GW as of December 2025, reflecting the country’s steady progress in expanding both conventional and renewable energy infrastructure. The latest capacity figures underline India’s growing focus on clean energy while maintaining the stability of its power grid through conventional sources.
Thermal power continues to account for a significant share of installed capacity, with coal remaining the single largest source. At the same time, renewable energy—led by solar and wind—has strengthened its position in the overall energy mix, reinforcing India’s long-term transition towards low-carbon power generation.
Installed Power Capacity by Source (MW)
- Coal: 219,610
- Solar: 135,809.94
- Wind: 54,510.93
- Large Hydro: 50,914.66
- Gas: 20,122.42
- Biomass/Cogeneration: 10,757.31
- Nuclear: 8,780
- Lignite: 6,620
- Small Hydro: 5,158.61
- Waste-to-Energy: 856.62
- Diesel: 589.20
Wind energy has also recorded consistent growth, particularly in states such as Gujarat and Tamil Nadu, while large hydro power continues to play a crucial role in grid balancing and peak load management. Biomass, small hydro, and waste-to-energy projects, though smaller in scale, contribute to decentralised and region-specific power generation.
India is currently among the world’s fastest-growing clean energy markets, driven by ambitious policy frameworks, falling renewable energy costs, and rising private sector participation. Under the leadership of Prime Minister Narendra Modi, India has consistently reaffirmed its commitment to energy transition and climate action through large-scale renewable energy deployment and long-term national targets.
The country has set an ambitious goal of achieving 500 GW of non-fossil fuel-based installed capacity by 2030, a milestone repeatedly underscored by the Prime Minister at global platforms.
Alongside domestic efforts, India continues to play a key role in advancing solar energy worldwide through the International Solar Alliance (ISA), promoting solar deployment across developing and emerging economies. Solar and wind energy are expected to account for the majority of new capacity additions in the coming years, supported by grid expansion and energy storage initiatives.
Going forward, the expansion of energy storage systems, transmission infrastructure, and grid modernisation initiatives will be critical to integrating higher shares of renewable energy and ensuring round-the-clock power availability.
