The recent passage of the Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India (SHANTI) Act, 2025, marks a major change in India's energy approach. This law fundamentally restructures the sector to boost nuclear power generation. By removing regulatory hurdles that limited growth for decades, the Act is expected to attract significant private investment, both from within India and internationally, to meet ambitious capacity goals.
India's 100 GW Nuclear Goal & Regulatory Overhaul
India's goal to drastically increase its nuclear power output to 100 GW by 2047 is a key shift for its energy strategy. This target, a big jump from the current 8.8 GW, is vital for powering strong economic expansion by ensuring a steady, reliable energy supply.
The SHANTI Act, 2025, is central to this effort. It aims to update India's nuclear rules, replacing older laws from 1962 and 2010. Most importantly, it allows private companies to invest in nuclear power for the first time since India's independence. This resolves long-standing issues over liability, which had blocked foreign investment and technology sharing for nearly 20 years after the 2005 India-US civil nuclear deal. Maria Korsnick, President and CEO of the Nuclear Energy Institute, called this reform a 'new day' for civil nuclear trade between the US and India, opening the door to more reactor types.
Global Nuclear Race & India's Position
Globally, about 413 GW of nuclear capacity is operational, with over 50 new reactors under construction, mostly in China and Russia. Most new reactors are being built in China and Russia. India's 100 GW target by 2047 puts it among the leaders for future growth, though China's plan to reach 150 GW by 2035 is faster.
While countries like the UK and France are also expanding nuclear power for climate goals, India's plan to use private capital for a large capacity increase is unique. Whether India can successfully deploy various reactor types, including advanced and small modular reactors (SMRs), will be crucial for its competitiveness. These technologies are still developing, and their final costs in India, versus large traditional reactors or fast-growing renewables, are still uncertain. The competition is intense.
Challenges: Execution, Cost & Competition
Introducing private sector participation alongside the ambitious 100 GW goal by 2047 brings significant execution risks. While the SHANTI Act aims to simplify investment, the long construction periods, massive initial costs, and complex nature of nuclear projects mean private sector commitment is vital but not guaranteed.
Historically, large nuclear projects worldwide have suffered from major cost overruns and delays. India's emerging private nuclear sector does not yet have a proven history of managing such complex undertakings. Maintaining strict safety standards and effective waste management across many private facilities will require strong regulatory oversight. The sheer scale of the planned expansion could challenge the existing regulatory capacity.
Also, dependence on imported parts for advanced reactors could lead to supply chain problems and higher costs. If advanced SMR technologies do not mature quickly or prove too expensive, India might struggle to meet its diversification goals efficiently, potentially falling behind countries with more efficient, government-led construction programs. Past issues with cost management in India's state-run energy projects might also make investors cautious.
Navigating the Path Forward
Analysts view nuclear energy's role in global decarbonization with cautious optimism, stressing that successful project execution and cost management are essential.
For India, making the SHANTI Act work means turning policy into reality. This requires ensuring the expanded nuclear fleet is safe, economically viable, and well-integrated into the power grid. The key challenges will be developing a skilled workforce, building a strong domestic supply chain, and balancing government goals with private sector financial interests to hit the 2047 target.
