Maharashtra has entered advanced discussions to set up first thorium-based power plants, marking a significant milestone in the state’s long-term clean energy transition. Through this initiative, the state aims to secure reliable baseload power while reducing dependence on fossil fuels and lowering electricity costs over the long run.
Engagement with DAE and NPCIL to Firm Up Project Plans
To move the proposal forward, the government is working closely with the Department of Atomic Energy (DAE) and the Nuclear Power Corporation of India Limited (NPCIL). The discussions focus on establishing two thorium-fuelled nuclear units on land owned by the state power utility.
Under the current proposal, one unit will have a capacity of 1,540 MW, while the second will add 440 MW. Together, these plants will replace two ageing thermal power stations operated by the utility, modernising the state’s generation mix.
Reducing Fossil Fuel Dependence
By deploying thorium-based nuclear capacity, Maharashtra seeks to ensure stable, round-the-clock electricity supply to support economic growth. At the same time, the shift away from coal-fired generation will help reduce carbon emissions and exposure to fuel price volatility.
The proposed thorium plants are estimated to generate electricity at around ₹3.50 per unit, making it more competitive than most thermal power options over the long term. Although the plants require higher initial capital investment, lower operating costs will likely offset it over their lifecycle.
Thorium Offers Safety and Sustainability Advantages
Thorium is increasingly being viewed as a safer and more sustainable alternative to conventional nuclear fuels. Experts point out that thorium reactors operate at atmospheric pressure and carry a significantly lower risk of meltdown compared to uranium-based systems. Moreover, India possesses one of the world’s largest thorium reserves. This strengthens the case for domestic deployment of thorium technology, enhancing energy security while leveraging indigenous resources.
Policy Coordination and Project Roadmap
The Maharashtra Institution for Transformation (MITRA), the state government’s policy think tank, is coordinating the project’s design and implementation roadmap. The agency is working to align technology choices, regulatory requirements, and financing structures to ensure timely execution. Earlier, Maharashtra had signed an agreement with Russia’s state-owned nuclear company to explore thorium-based small modular reactors. However, collaboration with India’s nuclear utility is now considered a more practical and cost-effective approach.
Regulatory Clearances
Looking ahead, state officials expect regulatory approvals and project clearances to progress in the coming months. As reported by businessworld.in, once cleared, the thorium-based plants could place Maharashtra at the forefront of advanced nuclear energy deployment in India, setting a precedent for clean, reliable, and future-ready power generation.
