Hitachi Energy inaugurates state-of-the-art transformers factory in China

Hitachi Energy's state-of-the-art transformers factory in Chongqing, China

 The new facility addresses the fast-growing demand for electrifying the evolving grid in the region through innovative and digital manufacturing. 

Hitachi Energy, a global technology leader that is advancing a sustainable energy future for all, inaugurated its new state-of-the-art transformers factory in Liangjiang New Area, southwest China’s Chongqing Municipality.

One of the largest of Hitachi Energy facilities globally, the leading-edge smart facility incorporates the latest digital manufacturing technologies. It reinforces Hitachi Energy’s commitment to meet the fast-growing customer demand.

The energy transition in China requires deployment of innovative technologies at scale and with speed. The new facility is a good example of the needed collaboration with partners and all involved stakeholders. It is another example of our commitment to accelerate investment in innovation, digitalization and people to support our customers to advance the world’s energy system to be more sustainable, flexible and secure.

Claudio Facchin, CEO, Hitachi Energy

The facility was originally established in 1998 and is the company’s first joint venture in western China. Over the decades, it has evolved into one of Hitachi Energy’s largest transformer research and manufacturing bases. It provides power transformers, shunt reactors, high-voltage direct current (HVDC) converter transformers, insulation kits, and services.

The company relocated to Liangjiang New Area in early 2023, transforming itself into a modern intelligent factory with significantly improved production efficiency. With the use of industrial automation and robotics, the manufacturing processes have become faster and more precise. Energy management systems have been put in place to facilitate real-time acquisition, analysis, and the timely maintenance of equipment and production data, ensuring cost-effectiveness throughout the value chain. In line with the company’s sustainability efforts, the modern factory has incorporated environmentally responsible measures to reduce the overall carbon footprint.

Thanks to the unwavering support from the partners and all involved stakeholders, the Chongqing factory has become a prominent example for Hitachi Energy to drive local innovation with global technology and lead high-quality development in the industry. With a focus on intelligent operations and continuous innovation in the new facility, Hitachi Energy will further deepen the local presence, and continue to work with customers and partners to contribute to advancing a sustainable energy future in China and beyond.

JinQuan Zhang, Region Head of Greater China and Executive Vice President, Hitachi Energy

Around 2,000 power transformers have been delivered out of the Chongqing factory to key projects such as Three Gorges hydro project; Changji-Guquan, the world’s first ±1,100 kV ultra-high-voltage direct current (UHVDC) transmission link; Longdong-Shandong ±800 kV UHVDC transmission project; and Al Dhafra PV2 solar project in Abu Dhabi.
