India has officially secured its position as a global energy leader, now operating the world’s sixth-largest nuclear reactor fleet to meet its growing electricity demands. This expansion allows the nation to generate over 3 percent of its total power from nuclear sources, significantly diversifying its energy basket. The government confirmed the current total installed capacity at 8.78 gigawatts during a recent policy review on January 1, 2026.

Expanding India’s Nuclear Capacity and 8.78 GW Goal

The Department of Atomic Energy continues to push for rapid infrastructure growth to support the country’s carbon-neutrality targets. Currently, the 8.78 gigawatt capacity serves as a foundation for a much larger long-term roadmap. Engineers are focused on maximizing the output of existing Pressurized Heavy Water Reactors (PHWR) while integrating more advanced cooling technologies. By maintaining this sixth-place global ranking, India proves it can manage large-scale nuclear operations safely and efficiently. Recent data suggests that the sector has maintained a 10% year-on-year growth rate in total output since 2023.

Success in this sector stems from decades of domestic research and international partnerships. The central government is currently overseeing the construction of several new units that will eventually push the capacity beyond 12 gigawatts by the end of the decade. These large-scale plants are essential for providing a stable base-load of electricity to India’s massive industrial corridors. As grid stability becomes more critical, the role of nuclear energy in the national power mix is set to grow even further.

Indigenous Small Modular Reactor (SMR) Development

Innovation remains at the heart of the latest energy strategy, with a new focus on compact and flexible power solutions. According to New India Samachar, the government has initiated the design and development of indigenous 200-megawatt and 55-megawatt Small Modular Reactors (SMRs). These reactors utilize Pressurized Water Reactor (PWR) technology, making them easier to deploy in diverse geographic locations compared to massive traditional plants. SMRs offer a faster construction timeline and lower initial capital costs, which could revolutionize how decentralized regions access clean energy.

Experts believe these indigenous designs will reduce the country’s reliance on foreign technology while creating a new export market for Indian engineering. The 55-megawatt variant is specifically designed for industrial captive power, providing a reliable carbon-free alternative for heavy manufacturing. “India is positioning itself as a hub for modular nuclear technology,” noted a lead energy consultant during a technology summit. As these PWR-based systems move from the design phase to prototype testing, India solidifies its reputation as a pioneer in the global nuclear landscape. The future of the nation’s power grid looks increasingly nuclear, driven by both massive fleet expansions and nimble modular innovations.
