India's Nuclear Energy Expansion: Green Finance, Private Participation and the 100 GW by 2047 Roadmap Category: Energy, Economy, Environment and Science & Technology | GS: GS Paper II, GS Paper III | Date: 2 September 2026
WHY IN NEWS
- India's nuclear-energy transition has moved from a capacity-expansion question to a financing, technology and human-capital question.
- Officials and industry leaders have argued that India's green-finance architecture should recognise nuclear power if the country is to mobilise the very large investment required for the Nuclear Energy Mission.
- India is targeting 100 GW of nuclear capacity by 2047, compared with about 8.78 GW at present.
- The official roadmap envisages about 22 GW by 2031-32, followed by a much larger build-out involving NPCIL, other public enterprises, State entities, joint ventures and private participation.
- The issue is important for UPSC because it links energy security, climate mitigation, industrial policy, strateGIc technology, federal regulation, liability, green taxonomy, skilled employment and India's Net Zero 2070 pathway.
