India’s Nuclear Energy Sector: Policy, Growth & Key Companies (2025)
🌍 Global Momentum: Clean Energy & The Return of Nuclear
The global transition towards clean energy has reignited interest in nuclear energy stocks across markets. As countries pursue decarbonisation, nuclear power is once again recognised as a zero-carbon, reliable baseload energy source.
India has aligned strongly with this global shift, setting ambitious long-term goals:
- 1,00,000 MW (100 GW) nuclear capacity by 2047
- Net-zero emissions by 2070
This renewed focus is creating long-term opportunities for companies involved in reactor construction, heavy engineering, precision manufacturing, EPC services, cooling systems, and nuclear fuel cycle technologies.
🇮🇳 Growth in India’s Nuclear Energy Sector
India’s nuclear sector growth is driven by strategic national objectives, rising power demand, and global technological advancements. The country aims to scale nuclear capacity from current levels to an ambitious 100 GW by 2047.
- 22+ new nuclear reactors planned
- Fast-track approval for 10 indigenous PHWR reactors
- ₹20,000 crore government allocation for nuclear development
- 49% FDI permitted in nuclear component manufacturing
- Private sector participation enabled across supply chain
- Development of Small Modular Reactors (SMRs)
India is also strengthening partnerships with global nuclear leaders such as EDF (France), Westinghouse & GE (USA), and Russia, supporting technology transfer and domestic manufacturing capabilities.
