India Plans 100 GW Nuclear Power Capacity by 2047

India has outlined an ambitious plan to expand its nuclear power capacity more than tenfold, from the current 8.8 gigawatt (GW) to 100 GW by 2047. The announcement was made by Ghanshyam Prasad, Chairperson of the Central Electricity Authority (CEA), highlighting the country’s long-term strategy to strengthen clean and stable energy sources as part of its development vision.

Ambitious nuclear energy roadmap

The proposed expansion represents a significant acceleration in India’s nuclear energy programme. According to the CEA, achieving 100 GW capacity will require rapid infrastructure development and sustained investment over the next two decades. The roadmap focuses primarily on building new nuclear power plants, while existing facilities will continue operating at current capacity levels.

Policy and regulatory reforms underway

To support this expansion, the government has identified the need for legislative and regulatory changes. The implementation of frameworks such as the Shanti Act is seen as an initial step, but further work is ongoing to establish rules, procedures and operational guidelines. Authorities are currently consulting stakeholders to refine policies and ensure smoother execution of projects.

Key challenges and focus areas

The roadmap highlights several critical challenges, including fuel security, site selection, cost reduction and availability of skilled human resources. Efforts are being made to standardise procedures and streamline approvals to reduce tariffs and improve efficiency. Emerging technologies such as Small Modular Reactors (SMRs) are also being considered, though they remain in developmental stages globally.

Important Facts for Exams

• India aims to expand nuclear power capacity from 8.8 GW to 100 GW by 2047.
• Nuclear energy is considered a stable and low-carbon power source.
• Small Modular Reactors (SMRs) are emerging nuclear technologies under development.
• Central Electricity Authority (CEA) is the apex body for power sector planning in India.

Future outlook and sector participation

The nuclear sector is expected to witness increased participation from multiple players in the coming years, moving beyond the current limited operator base. States are being encouraged to identify suitable land for new projects, which remains a crucial prerequisite for expansion. With nuclear power offering consistent and reliable electricity generation, the planned scale-up is expected to play a key role in India’s energy security and transition towards cleaner energy systems.
