The government has released draft rules for private companies to own and operate nuclear plants, marking a major policy shift. While energy giants like NTPC and Adani Power are scouting sites, investors should note that nuclear projects involve high costs and long timelines, making immediate earnings unlikely.
India’s energy sector is set for a massive change as the government moves to allow private companies to own and operate civil nuclear power plants. This shift is enabled by the Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India (SHANTI) Act of 2025 and new draft rules notified in August 2026. This policy aims to move the nation toward its goal of 100 GWe of nuclear capacity by 2047.
Impact on Private Players and Equipment Firms
The new framework allows private companies to participate across the nuclear value chain, including in-principle approvals for site preparation and selecting technologies like Small Modular Reactors (SMRs). Large power generators, including NTPC, Adani Power, Tata Power, Reliance, and Jindal Nuclear, are reportedly evaluating potential project sites. Additionally, engineering and manufacturing companies are expected to play a critical role. Firms such as Larsen & Toubro (L&T), BHEL, Power Mech, MTAR Technologies, and Walchandnagar Industries are positioned as key beneficiaries for equipment supply and construction contracts.
Valuation and Market Reality
Investor excitement surrounding these policy changes has already moved stock prices, but the financial reality is more complex. Many power and infrastructure stocks are trading at elevated valuations. For instance, Adani Power is currently trading at approximately 31.05 times its earnings, well above its five-year average. Similarly, BHEL trades at a valuation of 92.3 times earnings. Some stocks have seen significant gains in 2026, with Adani Power rising over 43% and MTAR Technologies surging nearly 195% year-to-date, reflecting high expectations.
However, analysts warn that it is too early to expect a jump in profits. Finalizing the rules and standard operating procedures is expected to take another six to ten months. Because nuclear projects have a long gestation period—meaning it takes many years from planning to electricity generation—near-term financial impact is unlikely. Investors should distinguish between long-term policy potential and short-term earnings growth.
Risks and Monitorables
Unlike solar or wind projects, which can be commissioned relatively quickly, nuclear energy comes with unique challenges. Private operators will face strict regulatory oversight, and safety and liability rules remain a focal point for the government. The transition of liability from the state to private operators is a significant factor that could influence project costs and timelines. Furthermore, the complexity of technology and the need for specialized talent mean that only companies with strong balance sheets and technical expertise may successfully execute these projects.
For investors, the next important update will be the finalization of the SHANTI rules and the announcement of specific project tenders. Tracking the progress of pilot projects and management commentary on capital spending plans will be essential to gauge when this potential long-term opportunity might begin to contribute to company revenues.
