L&T Delivers Final Steam Generator for Kaiga Nuclear Plant, Boosting India’s Nuclear Power Drive

Larsen & Toubro (L&T) Heavy Engineering has achieved a key milestone by dispatching the fourth and final Steam Generator (SG) for the Kaiga Atomic Power Station in Karnataka. This successful delivery marks the completion of a critical component set for one of India’s upcoming 700 MWe Pressurised Heavy Water Reactors (PHWR), a part of the country’s ambitious 10x700 MWe nuclear expansion programme.

What makes this achievement stand out is not just the completion of the fourth SG, but the fact that it was delivered a remarkable nine months ahead of schedule. L&T managed to manufacture and dispatch the entire set of four steam generators within just 45 months, with the first one ready in a record time of 33 months — setting new global standards in nuclear equipment production and timely delivery.

Steam generators play a vital role in nuclear power plants. Acting as large-scale heat exchangers, they transfer heat from the reactor’s core to convert water into steam, which then drives turbines to generate electricity. The quality and reliability of these components are essential for the safety and efficiency of nuclear operations.

L&T has long been a trusted name in this domain. With more than 42 steam generators built for India’s nuclear plants so far, the company’s manufacturing expertise is well-established. These SGs are fabricated using advanced technologies within dust-free enclosures at L&T’s A.M. Naik Heavy Engineering Complex in Hazira, Gujarat. The facility’s cutting-edge infrastructure allows it to meet the stringent quality standards required for nuclear-grade equipment.

The dispatch ceremony of the final SG was attended by senior officials from the Nuclear Power Corporation of India Ltd. (NPCIL), underlining the strategic partnership between L&T and India’s premier nuclear power body. Anil V Parab, Whole-time Director and Senior Executive Vice President at L&T Heavy Engineering, described this accomplishment as a reflection of the company’s strong nuclear quality culture and its contribution toward national development goals.

This milestone comes at a time when India is intensifying its focus on clean and sustainable energy. The Kaiga plant already houses four 220 MWe PHWRs and is currently expanding with two more 700 MWe units. These additions are part of India’s broader aim to triple its nuclear power capacity to 22.48 GWe by 2032 and ultimately reach 100 GWe by 2047 under the “Viksit Bharat 2047” vision — a roadmap to position India as a developed, energy-secure nation.

L&T’s contribution also aligns with the Aatmanirbhar Bharat (self-reliant India) initiative, as it showcases indigenous capabilities in manufacturing highly specialized and critical nuclear components. In a world increasingly leaning toward clean energy, such domestic capabilities not only strengthen India’s energy security but also reduce dependence on foreign suppliers for strategic infrastructure.

Looking ahead, L&T’s proven record and forward-looking investments in nuclear technology will continue to support India’s transition toward a greener future, with nuclear energy expected to play a central role in meeting both rising energy demand and the nation’s climate goals.
