Roadmap for achieving 100 GW Nuclear Capacity by 2047
14th October 2025
The Committee constituted by the Ministry of Power to prepare a roadmap for 100 GW nuclear capacity by 2047 has published its report dated 27th day of June 2025 on 14th October 2025
This is a very comprehensive report and gives a fully granular idea of status of and prospects for India's nuclear power sector
We have captured Executive Summary of this 140-page report. This is a very crisp and effective self-speaking ppt type summary, and does not need any further explanation
We have also captured Committee`s assessment of expected electricity energy requirement for 2046-47 and 2049-50 and the likely Capacity Mix in 2047
Overview
- Power sector contributes more than 40% of global energy related emission, and in India the same is more than 52 % (as per data published by NITI Aayog India Climate & Energy Dashboard for year 2020: 1,171 million tons CO2e from electricity generation out of total 2,238 million tons CO2e from energy sector)
- Adoption of low carbon pathways for the power sector will be crucial in achieving India`s 2070 Net Zero emission target. The obvious strategy would be to increase contribution from non fossil based energy resources, enhance energy efficiency and to use carbon capture technology in case of fossil fuel resources
- Nuclear is one of the cleanest forms of energy. On life cycle terms, nuclear has lower CO2 emission per kWh than even solar PV
- In order to fulfill the promise of nuclear towards a cleaner and greener tomorrow, Government of India has taken decisive steps for reaching 100 GW nuclear capacity by 2047
- The budget announcements on 1st February 2025 strengthened the resolve further by announcing a Nuclear Energy Mission for Viksit Bharat which would be facilitated through the amendments to the Atomic Energy Act and the Civil Liability for Nuclear Damage Act.
- In order to prepare a roadmap for 100 GW nuclear capacity by 2047, Ministry of Power had constituted a committee. The Committee held several rounds of discussions on all aspects of the journey towards 100 GW by 2047. Challenges have been identified and recommendations have been given, through its report

Expected Electricity and Peak Requirement
- We have also picked up Committee`s assessment of expected electricity energy requirement (in billion units, or same as TWh) and Peak Electricity Demand (in GW) for 2046-47 and 2049-50
