Celebrating 25 years of transformer innovations in India

Hitachi Energy celebrated 25 years of transformer manufacturing in India with a lively event at its Maneja facility.

It was a tribute to a journey that began in 1999 with a modest order from Gujarat Energy Transmission Corporation Limited (GETCO). That first step, involving two 220-kilovolt (kV) power transformers, laid the foundation for what has evolved into a robust, nationwide operation. Today, Hitachi Energy operates five factories across Gujarat state, producing a diverse range of power and distribution transformers, as well as transformer components and insulation for utilities, industries, and infrastructure projects.

Reflecting on this milestone, Tarun K. Garg, Engineering Manager, Hitachi Energy shared:

“I draw inspiration and fulfillment from my 25 years of rich experience at Hitachi Energy, where a stable work environment has allowed me to contribute to key power transformer supply projects. Sharing insights and deep technical expertise through technical forums supported by Hitachi Energy has been a rewarding experience. I take great pride in contributing to critical infrastructure.”

A highlight of the event was the inauguration of the newly built extension of the core coil assembly area in the large power transformer factory, including a new vapor-phase transformer drying process plant. The increased factory space boosts production capacity, streamlines operations, and creates room for future growth, ensuring faster delivery and greater flexibility to meet India’s rising energy demands.

In his keynote, Carlos Pettinau, Hub APMEA Manager Transformers Business, Hitachi Energy, reflected on the company’s evolution in India: 

“We began our journey with GETCO, and today, we stand proud of our contributions to India’s energy infrastructure. Over the years, we’ve expanded our capabilities to meet evolving grid demands, delivering advanced transformers designed and manufactured in India. From compact distribution transformer units to Extra High Voltage and Ultra High Voltage AC transmission transformers up to a voltage class of 765 kV, including HVDC transformers and India’s first locally developed 1200 kV UHV AC transformer, our portfolio reflects engineering excellence and a deep commitment to the country’s progress. I want to thank our employees for their expertise, and our customers for their trust. Together, we’ve built a legacy of reliability.” 

The event showcased Hitachi Energy’s technological milestones, including its pioneering work in ester-filled transformers, HVDC converter units, and specialized solutions for Indian railways and data centers. Separately, Hitachi Energy has demonstrated its engineering reliability through more than 40 successful short-circuit tests, validating its technology across various transformer ratings. 

Industry leaders shared their vision for the future. Kundan Rathod, Chief Engineer, Projects of GETCO, emphasized the importance of continued collaboration to meet India’s evolving energy needs: 

“Congratulations to Hitachi Energy on 25 years of transformer manufacturing in India. Your dedication to quality and innovation has strengthened our partnership and helped power millions of homes. We look forward to continuing this journey toward a sustainable energy future together.”

From humble beginnings, Hitachi Energy India has grown into a leading transformer manufacturer by effectively navigating intense competition, stringent technical standards, and shifting market dynamics. The company has consistently embraced challenges – such as the demanding Dynamic Short Circuit Test – achieving exceptional first-pass yields in both global and Indian high-power laboratories. In just a decade, Hitachi Energy India has set new benchmarks with generator step-up units (GSUs), railway feeding units, and auto-connected transformers, many of which established global records.

Mastery of complex short-circuit qualifications positioned the organization ahead of the market, enabling it to secure major generation and transmission projects. Backed by Hitachi Energy’s technology leadership, the company continues to deliver reliable solutions for critical applications, including the world’s highest-rated 765 kV GSUs and specialized transformers powering semi-high-speed rail.

This celebration was not just about reflecting on our journey so far; it was also about building the future together. With a legacy built on trust, performance, and partnership, Hitachi Energy remains a driving force in shaping India’s sustainable energy future.
