India’s Energy Transition
India’s Energy Transition
India’s power sector is undergoing a major structural transformation, with total installed power capacity reaching approximately 552 GW. The transition is driven by rapidly rising domestic energy demand as well as the need to reduce carbon intensity, strengthen energy security, and build a sustainable low-carbon economy. India is therefore pursuing a multidimensional energy strategy that combines renewable energy expansion with continued thermal power support, nuclear development, green hydrogen, bio-energy, and improvements in energy infrastructure. This approach seeks to balance immediate electricity requirements with long-term environmental and climate objectives.
Renewables, Conventional Power and Energy Security
Non-fossil fuel sources now account for more than 54% of India’s installed generation capacity, strengthening the country’s position as a leading renewable energy producer. Solar power has become the largest component of the clean-energy portfolio, with approximately 164.59 GW of installed capacity. India has also emerged as one of the world’s fastest-growing solar markets. Wind energy is another major pillar, with installed capacity of around 58.14 GW, placing India fourth globally. The domestic wind manufacturing ecosystem has a capacity of approximately 24 GW, with 70–80% of components sourced domestically.
Bio-energy contributes approximately 11.75 GW through grid-connected projects and is being supported by decentralized Compressed Bio-Gas and Bio-CNG facilities. India also possesses an estimated untapped geothermal energy potential of around 10,600 MW, providing an additional long-term clean-energy opportunity.
At the same time, coal remains central to India’s energy security. It provides nearly 55% of primary energy and more than 70% of electricity generation. Domestic coal production reached approximately 1,040.08 million tonnes, helping reduce coal imports required by thermal power plants by 27.4%. India also operates 22 major refineries and remains one of the world’s leading oil-refining nations. LPG access has expanded significantly, with coverage reaching approximately 107.2%, supporting cleaner household cooking and reducing dependence on traditional fuels.
Nuclear Power, Green Hydrogen and Policy Initiatives
Nuclear energy is emerging as an important source of reliable low-carbon baseload electricity. India’s nuclear power capacity currently stands at approximately 8.78 GW, with a long-term target of 100 GW by 2047. The 500 MWe Prototype Fast Breeder Reactor at Kalpakkam achieved operational criticality, marking an important milestone in India’s three-stage nuclear programme and its objective of closing the nuclear fuel cycle.
Green hydrogen is another emerging component of the energy transition. India has developed more than 8,000 tonnes per annum of green hydrogen production infrastructure. The rollout of India’s first domestically developed hydrogen fuel-cell train on the Jind–Sonipat corridor reflects the growing effort to move hydrogen technology from production to practical applications.
Several policy interventions are supporting this transformation. The PM-Surya Ghar: Muft Bijli Yojana aims to install rooftop solar systems in 1 crore households. More than 51.58 lakh homes have already been connected, with around 19 lakh households achieving near-zero electricity bills. The Pradhan Mantri Surya Sarovar Yojana targets 5,000 MW of floating solar photovoltaic capacity along with approximately 10,000 MWh of integrated energy storage. The Surface Coal/Lignite Gasification Scheme promotes cleaner utilization of coal and lignite, targeting 75 million tonnes per annum of utilization and a 100 million tonne conversion milestone by 2030.
The SHANTI Act provides a statutory framework for private-sector participation in nuclear power, introduces a liability cap of 300 million Special Drawing Rights, and provides a statutory framework for nuclear safety regulation. The Samudra Manthan Initiative strengthens offshore hydrocarbon exploration through seismic mapping, ultra-deepwater drilling, and supporting coastal infrastructure. The GOBARdhan Scheme promotes the conversion of cattle dung and organic waste into Compressed Bio-Gas and other useful resources, supporting both the rural bioeconomy and clean-fuel supply.
Significance of India’s Energy Transition
India’s energy transition has major implications for energy independence. Expanding domestic renewable, nuclear, bio-energy, and other non-fossil resources can reduce dependence on imported hydrocarbons and improve resilience against international energy-price volatility. Greater domestic energy production can also reduce external vulnerabilities and support India’s broader objective of becoming more self-reliant in strategic sectors.
The transition is equally important for grid modernization and decarbonization. Solar and wind power are expanding rapidly, while energy storage, nuclear generation, and modern transmission infrastructure can provide the flexibility and reliability required for a cleaner electricity system. The development of domestic manufacturing in solar modules, wind turbines, batteries, hydrogen technologies, and related equipment can further strengthen local supply chains, create employment, and reduce dependence on imported technologies.
The transition also has an important social dimension. Rooftop solar, decentralized renewable-energy systems, and wider access to clean cooking fuels can reduce household energy expenditure and improve the reliability of energy access. These benefits are particularly significant for rural households, where decentralized energy solutions can improve living standards while contributing to environmental sustainability.
Key Challenges
The rapid expansion of renewable energy also creates several challenges. Solar and wind generation depend on weather conditions and therefore fluctuate throughout the day and across seasons. Integrating large quantities of intermittent electricity into the national grid requires large-scale energy storage, flexible generation, accurate forecasting, and advanced grid-management systems.
India also continues to depend heavily on coal for baseload electricity and grid stability. A rapid reduction in thermal power without sufficient alternative firm capacity could create risks for electricity supply, particularly during periods of peak demand. The transition must therefore balance decarbonization with reliable and affordable electricity.
Another major challenge is the high capital requirement. Large investments are necessary for battery storage, pumped-storage systems, transmission networks, offshore exploration, nuclear power plants, and emerging clean-energy technologies. In addition, clean-energy technologies depend on critical minerals, rare-earth elements, advanced components, and specialized manufacturing capabilities. Global supply-chain disruptions can therefore affect the cost and pace of India’s transition.
Way Forward and Conclusion
India should accelerate the deployment of Battery Energy Storage Systems and pumped-storage hydropower to manage renewable-energy fluctuations and strengthen grid reliability. High-voltage green-energy corridors should be expanded to transmit electricity efficiently from renewable-rich regions to major industrial and urban demand centres. Public-private partnerships can mobilize investment in advanced nuclear technologies, Small Modular Reactors, green hydrogen, energy storage, and distribution infrastructure.
Critical-mineral security should also receive greater attention through strategic international partnerships, domestic exploration, processing, substitution, and recycling. At the same time, domestic manufacturing capabilities should be strengthened to create resilient clean-energy supply chains.
India’s multidimensional energy strategy seeks to balance immediate energy-security requirements with an ambitious transition toward cleaner sources of power. While coal continues to provide essential baseload support, rapid growth in solar, wind, bio-energy, nuclear power, and green hydrogen is reshaping the country’s energy landscape. Strengthening storage, transmission, domestic manufacturing, critical-mineral security, and private investment will be essential for creating a resilient, self-reliant, affordable, and sustainable energy system.
