India's Nuclear Energy Expansion: 100 GW Target by 2047
India aims for 100 GW of nuclear power by 2047, supported by government initiatives and private sector involvement. New technologies like small modular reactors are being developed to enhance applications beyond traditional power generation.

India's nuclear energy capacity currently stands at 8.8 GW, with several projects underway. Notably, five pressurized heavy water reactors (PHWRs) are under construction, contributing 3,500 MW, and four pressurized water reactors (PWRs) adding 4,000 MW.
By 2031-32, these projects are expected to become operational. The Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India (SHANTI) Act, 2025, facilitates private sector involvement in nuclear activities.
Major players like NTPC Limited and Adani Group are committing investments to expand nuclear capacity. Additionally, the sector is exploring hydrogen production from nuclear heat, positioning itself for broader energy applications. However, challenges such as regulatory complexities and high capital costs remain significant barriers to expansion.
