India has announced a roadmap to achieve 100 GW of nuclear power capacity by 2047, seeking to add 30 GW through private sector participation. Enabled by the SHANTI Act 2025, this plan requires an estimated ₹7.5 lakh crore investment, aiming to balance energy security with a new public-private investment model.
India is undertaking a structural change in its energy sector, moving away from a complete state monopoly in nuclear power toward a model that invites private and foreign investment. The government has set a target to expand its nuclear energy capacity to 100 gigawatts (GW) by 2047. This initiative, supported by the SHANTI Act 2025, allows for private and foreign equity participation of up to 49% in nuclear energy projects, a significant departure from previous policies.
The scale of this ambition is substantial, requiring an estimated ₹7.5 lakh crore in capital spending. The strategy is split between the existing state framework and new private capacity. While the Nuclear Power Corporation of India Limited (NPCIL) continues to lead with a large portion of the capacity goals, the government expects the private sector to contribute approximately 30 GW. This expansion will utilize both large-scale indigenous reactors and Bharat Small Reactors (BSRs), which are modular and designed to be deployed more flexibly than traditional, massive power plants.
Challenges and Execution Risks
While the policy shift opens a new sector for long-term investment, the practical execution of nuclear projects comes with significant hurdles. Nuclear power plants are extremely capital-intensive, and the cost to build them remains much higher than solar, wind, or thermal power alternatives. Investors should understand that these projects involve very long construction timelines, which can create uncertainty around project returns and cash flow stability for private companies involved.
Another critical factor for the market is financial viability. Unlike smaller energy projects, nuclear infrastructure requires a unique financing architecture that can withstand the risks of multi-year construction and high initial costs. The sector's success will depend on whether the government can create a bankable framework that makes these projects predictable and attractive for private capital. Furthermore, developing a robust local vendor ecosystem is essential, as the supply chain for high-technology nuclear equipment must be mature enough to support this rapid expansion.
The next important phase for the industry will be the development of the vendor ecosystem and the announcement of initial pilot projects under the new private participation rules. Market participants will likely watch for clarity on project financing models, timelines for the first private-led reactor commissioning, and the government's progress toward the interim goal of 22 GW by 2031-32. As the sector transitions, the ability of companies to manage execution complexity and cost control will be the primary monitorable for long-term energy infrastructure development.
