What is India Energy Journey?

India Energy Journey encompasses the evolution of the country’s power sector from coal-dominated to a diversified mix of renewable, nuclear, and clean energy sources. Non-fossil sources now account for over 54% of installed capacity, with solar leading the renewable component at 164.59 GW, followed by wind at 58.14 GW and bio-energy at 11.75 GW.

Coal still accounts for nearly 55% of primary energy needs and over 70% of electricity generation, but its share is gradually declining. India is the world’s fourth-largest crude refiner with 22 refineries, and national LPG coverage has grown to 107.2%. The Nuclear Energy Mission targets 100 GW by 2047, with the 500 MWe Prototype Fast Breeder Reactor at Kalpakkam achieving first criticality in 2026.

Why is India Energy Journey in News?

India Energy Journey is in the news because of major milestones: the 500 MWe Prototype Fast Breeder Reactor achieved first criticality; India’s first indigenous hydrogen fuel cell-powered train began operating in July 2026; and PM-Surya Ghar has benefited 51.58 lakh households.

The SHANTI Act, 2025, permits private-sector nuclear participation and grants statutory status to the Atomic Energy Regulatory Board (AERB). The government has also launched schemes like Samudra Manthan for offshore oil exploration and GOBARdhan for bioenergy. For more details, refer to the PIB release.

Key Features of India Energy Journey

• Renewable Leadership: Solar (164.59 GW), wind (58.14 GW), and bio-energy (11.75 GW) drive the clean energy transition.
• Nuclear Expansion: PFBR at Kalpakkam; SHANTI Act enables private participation; target of 100 GW by 2047.
• Green Hydrogen: 8,000 tonnes per annum capacity commissioned; first hydrogen fuel cell train operational.
• Energy Security: Coal gasification target of 100 MT by 2030; Samudra Manthan for offshore oil and gas.
• Rooftop Solar: PM-Surya Ghar targets 1 crore households; over 51 lakh households already benefited.

Challenges in India Energy Journey

• Coal Dependence: Coal still accounts for over 70% of electricity generation, making decarbonisation difficult.
• Grid Integration: Variable renewable energy requires significant investment in storage and grid modernisation.
• Nuclear Liability: The Civil Liability for Nuclear Damage Act remains a concern for private investors.
• Land Acquisition: Renewable projects face land acquisition challenges and local opposition.
• Financing: The energy transition requires massive capital investment, estimated at hundreds of billions of dollars.

Way Forward for India Energy Journey

To accelerate India Energy Journey, the government should focus on energy storage solutions—pumped hydro, battery storage—to address grid integration challenges. Scaling up green hydrogen production and reducing the cost of electrolysers can support industrial decarbonisation.

Speeding up the nuclear expansion through private participation and liability insurance mechanisms is essential. Strengthening the grid infrastructure and promoting smart metering can improve efficiency. International collaborations, especially in technology transfer and financing, can accelerate the transition. For international best practices, refer to the IRENA.
