Hitachi Energy India secures order from Power Grid to supply 30 units of 765-kilovolt transformers

Hitachi Energy India on Thursday, June 26, bagged a supply order from Power Grid Corporation for 30 units of 765-kilovolt (kV) 500 megavolt-ampere (MVA) single-phase transformers.

The energy company will manufacture the transformers at its factories in Maneja, Vadodara and Gujarat. It will also align its delivery timelines with Power Grid’s transmission building plans, Hitachi Energy India said in a regulatory filing to the bourses.

Once installed, these transformers can transmit the power equivalent to the average power consumption of 30 million households in India, it added.

UHV AC 765 kV transformers will enhance the power grid's security, reliability and efficiency, helping to meet increasing energy demands, the statement said.

Commenting on the order, N Venu, the Managing Director and CEO of Hitachi Energy India, said: “From a technology provider perspective, this shift helps us plan capacity investments, reserve supply chains, and ensure timely delivery.”

“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,” Venu further stated.

It further stated that increasing demand for grid infrastructure in India and globally has led utilities to shift their planning horizons from near-term project-based to longer-term program-based.

According to the company, “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.”

Recently, Hitachi Energy successfully tested a 765 kV/ 400 kV 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 firm said.

On Thursday, shares of Hitachi Energy India closed at ₹19,410 apiece on the National Stock Exchange (NSE), down 1.15%. However, the announcement was made after the market closed.

As of June 26, 2025, Hitachi Energy India has a total market capitalisation of ₹86,514.96 crore, according to the data on the NSE.

Headquartered in Switzerland, it employs over 50,000 people in 60 countries and generates revenues of around $16 billion.
