Mukesh Ambani-led Reliance Industries Gautam Adanis Adani Group and the Tata Group are among some of the biggest names from the corporate world who are bidding for a central government tender to set up Bharat Small Reactors (BSRs) which aims to decarbonize high-emission industries such as steel and aluminum using nuclear power. The project is expected to attract Rs 35000 crore in investments from the private sector with the tender attracting bids from major players including Reliance Industries Adani Group Tata Group Hindalco the mining arm of Aditya Birla Group Vedanta and JSW Group Moneycontrol reported citing government officials. As per officials the government plans to allot the projects on a twin-unit basis which means each unit will have two BSRs of 220 MW the report said. Each twin unit is estimated to cost around Rs 6000-7000 crore it added. NPCIL is planning a total of either 12 such reactors (six twin units) or 14 reactors (seven twin units). The total investments by the selected companies could range from Rs 35000 crore to Rs 50000 crore the report quoted an official as saying. What are Bharat Small Reactors or BSRs? Bharat Small Reactors (BSRs) are indigenously-developed compact 220 MW pressurized heavy water reactors (PHWRs) aimed at providing a sustainable low-carbon energy solution for heavy industries like steel aluminum and metals which can act as captive power plants. There is a growing global demand for small nuclear reactors due to their flexibility scalability and lower costs compared to conventional large setups. The Narendra Modi government plans to boost Indias nuclear power capacity from 8.7 GW to 22.48 GW by 2031-32 and to 100 GW by 2047 and the deployment of BSRs is a major step towards the fulfilment of that ambitious project. Earlier this year the government announced the National Nuclear Energy Mission during the Union Budget. An initial outlay of Rs 20000 crore has been set aside for research and development of small reactors. How successful bidder will be incentivized? According to the report the company which secures the project will have to finance it in entirety which includes capital and operational expenditure. It will also be required to to reimburse NPCIL for all costs incurred across the lifecycle from pre-project assessments to decommissioning. In return the private firm will be granted assured long-term access to all the electricity generated through the nuclear reactors for captive use even as the BSR units are required to built under the supervision of the NPCIL and the state-owned company will also retain the operational control of the asset. When is the tender deadline? The tender being executed by the state-owned Nuclear Power Corporation of India Ltd (NPCIL) was first floated in January this year and deadline was set for June 30 2025. However the deadline was extended till September 30 upon the request of stakeholders who had sought more details about the project. Eligible bidders must have a minimum net worth of Rs 3000 crore and an annual power requirement of at least 2500 million units according to the tender document.
