India's much N-eeded in energy mix
Over the past decade, GoI has expanded investments in solar power, wind energy, transmission infrastructure and pumped hydro storage. Electric mobility initiatives and domestic battery manufacturing programmes are also being promoted as part of a broader strategy to reduce oil dependence.Recent geopolitical developments in the Gulf, which largely supply India's crude and LPG needs, have brought renewed focus to nuclear energy as a stable domestic source for baseload electricity. A milestone in India's nuclear programme was achieved in April, when a prototype fast-breeder reactor (PFBR) at Kalpakkam in Tamil Nadu attained first criticality. Developed indigenously by Bharatiya Nabhikiya Vidyut Nigam Limited (BHAVINI), the 500 MWe reactor marks India's formal entry into the second stage of its 3-stage nuclear programme envisioned by Homi Bhabha.Also a welcome development is the latest news of GoI reportedly considering measures that include assured power purchase agreements (PPAs), to attract private sector investments in the nuclear energy sector. It is also reportedly preparing to notify rules under SHANTI (Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India) Act 2025.India's nuclear strategy has been designed around the country's resource profile. While it has limited uranium reserves, it possesses some of the world's largest thorium deposits. The 3-stage programme was conceived to enable large-scale utilisation of thorium for power generation.Thorium is not a fertile or fissile material, and has to be converted to fissile Uranium-233 in a FBR. The third stage aims to use U-233-based reactors for sustained energy generation. PFBR is important for the eventual thorium utilisation. India's thorium reserves, largely located in coastal monazite sands in Kerala, Tamil Nadu, Andhra Pradesh and Odisha, are seen as a potential long-term strategic energy resource.Another significant development came with the passage of the aforementioned SHANTI Act last December. It modernises India's nuclear legal and regulatory framework, and allows limited private sector participation in nuclear projects.Traditionally, India's nuclear sector has been dominated by state-controlled entities. The Act is intended to streamline approvals, encourage investment, and support domestic manufacturing and technological partnerships. Reforms reflect recognition that achieving large-scale nuclear expansion will require both public and private participation.Bhabha Atomic Research Centre (Barc) is developing several advanced reactor designs, including 200 MWe Bharat Small Modular Reactor (BSMR-200), 55 MWe SMR-55, and a high-temperature gas-cooled reactor (HTGR) intended for hydrogen production. SMRs are expected to be modular, with modules produced under controlled conditions in a factory and assembled at the site in a short time. They are also expected to be safer, making them acceptable to the public.GoI has indicated that at least 5 indigenously designed SMRs will become operational by 2033. India has set a long-term target of achieving 100 GW of nuclear power capacity by 2047. At present, the country's installed nuclear capacity stands at about 8.7 GW, contributing around 3% of total electricity generation. Coal continues to account for nearly 70% of electricity production. Achieving the 100 GW target would require substantial expansion in infra, manufacturing, financing and human resources.The Strait of Hormuz disruption has reinforced the importance of diversifying India's energy mix and reducing exposure to external supply shocks. The current policy direction reflects a combination of RE expansion, electrification, domestic manufacturing and renewed emphasis on nuclear power.The broad objective of improving energy security through a diversified and domestically supported energy system must remain a central policy priority. RE, along with energy storage required to balance it, remains the major first step. Electricity can substitute fossil fuels in many sectors. Coal can be replaced by nuclear as a baseload supplier.Nuclear projects involve high upfront capital costs and long construction timelines. Land acquisition and public acceptance remain sensitive issues. Waste management, safety regulation and development of skilled technical manpower will require sustained institutional support.Thorium-based technologies, although strategically important for India, have not yet been deployed commercially at scale in the world. Policymakers will need to balance investments across nuclear, solar, wind, storage and grid modernisation to ensure affordability and energy security.SHANTI Act, PFBR, investment in SMRs and increased private participation suggest that nuclear energy may play a larger role in India's long-term energy strategy than anticipated. We need an integrated policy framework to achieve energy aatmanirbharta.Saini is senior research analyst, and Parikh is chairman, Integrated Research and Action for Development (IRADe), New Delhi
