Hitachi Energy India receives mega order of 765kV transformers from PGCIL
- June 26, 2025
Hitachi Energy India Ltd has received an order from Power Grid Corporation of India Ltd (PGCIL) to supply 30 units of 765kV, 500 MVA single-phase transformers.
In a release, Hitachi Energy India said that delivery timelines are aligned with customers’ transmission network building plans. The required transformers will be manufactured at Hitachi Energy India’s power transformer factory in Maneja, Vadodara, Gujarat, demonstrating its continued commitment to produce locally. The order value was not disclosed.
This order follows a bulk order for 30 units of 765kV reactors placed by PGCIL on Hitachi Energy India in Q4FY25, it is learnt.
The significance of 765kV transmission
Higher voltage transmission, such as 765 kV, enables efficient bulk transfer of power over long distances, significantly reducing losses and lowering operating costs, making electricity more affordable for consumers. 765 kV transformers reduce transmission lines and cut land use and construction costs while enhancing grid security with high capacity.
UHVAC 765 kV transformers enhance the power grid’s security, reliability, and efficiency, helping to meet increasing energy demands. Once installed, these transformers can transmit the power equivalent to the average power consumption of 30 million households in India, the release said.
Global technology prowess
“From a technology provider perspective, this shift helps us plan capacity investments, reserve supply chains, and ensure timely delivery,” said N Venu, Managing Director & CEO, Hitachi Energy India Ltd. “In addition to being the leading transformer manufacturer, Hitachi Energy brings its global technology prowess and local expertise across the energy value chain to be a partner of choice in mission-critical nation-building projects to inspire the next era of sustainable energy.”
Towards long-term planning
India needs a sustainable, flexible, and secure grid to advance its energy transition ambitions, accommodating the greater addition of renewable generation sources and the electrification of industries and transportation. This also substantially increased the demand for power transformers in India at 15 percent per year for the last two years. To seamlessly cater to the increasing demand for grid infrastructure in India and around the world, utilities are swiftly shifting their planning horizons from near-term project-based to longer-term program-based, the release observed.
Ester-filled transformer
It may be mentioned that global entity, Hitachi Energy, recently successfully tested a 765kV / 400kV single-phase, 250 MVA natural ester-filled oil transformer. This breakthrough innovation makes this transformer the first in the world at this voltage and power level, with the implementation of ester oil providing a biodegradable and safety-by-design option for operators of ultra-high-voltage alternating current (AC) grids, the release added.
