Transformers and reactors are essential electrical devices used in power systems to manage alternating current (AC) electricity, though they serve opposite primary functions.

The stock jumped as much as 7.74% to a high of ₹326.95 on the NSE.

The company's press release said that it has secured a large order for the supply of Generator Transformers for the Nuclear Power Corporation of India Limited’s (NPCIL) Kaiga Units 5 & 6 nuclear power project in Karnataka.

The order marks TARIL’s first order in the nuclear power sector, adding a new and strategically important segment to the Company’s growing portfolio of critical power infrastructure projects.

The order has been received from Megha Engineering and Infrastructure Limited (MEIL).

Details to know

Kaiga Units 5&6 comprise two indigenous 700 MWe (Megawatt Electrical) Pressurised Heavy Water Reactors (PHWRs) being developed by NPCIL at Kaiga, Karnataka.

The project is part of India’s indigenous 700 MWe PHWR programme, supporting the country’s efforts to expand nuclear power capacity while strengthening domestic technology and manufacturing capabilities.

Together, the two units will add 1,400 MW of nuclear generation capacity at the Kaiga site.

"The Generator Transformers will form a critical part of the electrical infrastructure of the project, supporting the evacuation of power generated by the nuclear power units and its integration with the transmission network," it added.

What the CEO said

Satyen Mamtora, Managing Director & CEO, Transformers and Rectifiers (India) Limited, said, “We are proud to mark our entry into the nuclear power sector with this order from NPCIL. Nuclear energy will play an important role in supporting India’s long-term energy security and clean energy ambitions, and we are pleased to contribute our transformer manufacturing capabilities to this critical national infrastructure."

The CEO added, "This order is also a strong validation of the trust placed in TARIL’s technology, engineering capabilities and ability to deliver equipment for highly critical power applications. As India advances towards its vision of Viksit Bharat 2047, strengthening indigenous capabilities and building a resilient and self-reliant energy ecosystem will be critical. We look forward to building on this opportunity and contributing to India’s nuclear power journey and its long-term energy security.”

Order impact on the company

The press release added that the order further strengthens TARIL’s positioning in the critical and high-value power infrastructure segment, as India continues to invest in expanding generation and transmission capacity.

The company has been strengthening its manufacturing capabilities, technology, and backward integration to address the evolving requirements of India’s power sector.

"With its entry into the nuclear power sector, TARIL aims to leverage its established expertise in high-voltage transformer manufacturing to support the requirements of critical power generation and transmission infrastructure and participate in India’s expanding nuclear energy ecosystem," it added.
