Hitachi ABB Power Grids expands transformer manufacturing in Vietnam

The 220kV power transformer is a critical link in the renewable energy delivery value chain

Hitachi ABB Power Grids recently supplied and commissioned a 220kV power transformer to Toji Group for the fast-tracking of the 50MWp Loc Ninh 5 Solar Power Plant to close out the Loc Ninh 1-5 series of solar projects with a total capacity of 800MWp in the southern province of Binh Phuoc, developed by Hung Hai Group. This makes it one of only two companies in Vietnam capable of manfacturing and supplying 220kV power transformers.

To power its economy – one of the fastest-growing countries in the region – Vietnam aims to tap into its tremendous renewable energy potential, seen in 4-5kWh per square metre of solar incidence and 3,000 kilometers of coastlines with consistent winds in the range of 5.5 to 7.3 metres per second.

The 220kV power transformer is a critical link in the renewable energy delivery value chain.

“We are excited to partner with Vietnam to strengthen its electrical networks and integrate more renewable energy. Expanding local manufacturing of essential equipment in the country will help us contribute to that,” said Chandan Singh, managing director, Hitachi ABB Power Grids Vietnam Co., Ltd. “Enhancing the manufacturing facilities of power transformers is one step in that direction.”

Hitachi ABB Power Grids’ power transformers facility in Hanoi recently upgraded its transformer manufacturing and testing facilities from 171 to 230kV. Local manufacturing capabilities will help meet quick turnaround times required for solar and wind power plants, creating a credible local service ecosystem and reducing transportation costs for customers.
