Power Grid Corporation of India (PGCIL) has inaugurated the nation’s first 315 MVA, 400/220/33 kV transformer filled with synthetic ester oil at its Bhiwadi substation in Rajasthan. The installation marks a significant step toward more environmentally conscious and safer grid infrastructure.
The commissioning event was attended by senior PGCIL leadership, including Chairman and Managing Director (CMD) Dr. R. K. Tyagi. He was accompanied by Director (Finance) Shri G. Ravisankar, Director (Operations) Shri Naveen Srivastava, Director (Projects) Shri Vamsi Rama Mohan Burra, Chief Vigilance Officer (CVO) Shri Naveen Kumar, Independent Director Shri Shiv Tapasya Paswan, and Executive Director NR-I Shri Alok Sharma.
This transformer represents a major technological advancement for India’s power sector. At 315 MVA, it is the largest installation of its kind in the country in both voltage class and capacity. Synthetic ester oil offers a higher fire point and superior biodegradability compared to conventional mineral oil, enhancing safety and reducing environmental impact. The unit was developed and manufactured by Hitachi Energy at its Maneja, Vadodara facility using the company’s global Trafostar platform. Hitachi delivered the transformer to PGCIL in July 2025.
KRYFS Power Components Limited supplied the transformer tank, supporting the development of reliable and future-ready energy infrastructure. PGCIL stated that this installation reinforces its commitment to India’s green energy mission.
