ABB wins 360-million dollar order for second high-voltage power link for China

Technology group to build 940 kilometer power system; couples local and global resources for aggressive completion schedule

Zurich, Switzerland, October 12, 2001 – ABB has won an order valued at US$ 360-million to supply converter stations for a high-voltage power transmission system linking the Three Gorges hydropower plant in central China to Guangdong Province. Under terms of the order, awarded by State Power Corporation of China, ABB will design and build the high-voltage direct current (HVDC) system for the 940-kilometer 3,000-megawatt link to Guangdong, an industrially advanced region with double-digit growth.

The link is part of the nationwide Western Region development program to transmit clean and renewable hydropower in the west to the densely populated consumer areas along the coast. It aims to improve the environmental performance of the fast developing Guangdong Province by substituting new fossil power plants in the future. “The HVDC technology that will be employed enables more efficient use of energy resources by transmitting large amounts of power over long distances with reduced losses,” says Richard Siudek, executive vice president and head of Utilities division. The amount of land required for the overhead transmission line as well as the visual impact of the line becomes reduced by application of the HVDC technology. ABB is already supplying converter stations for an 890-kilometer HVDC power link between Three Gorges and Shanghai.

The two-stage project will be delivered in 32 months. This will shave 30 percent off the normal timetable for a project of such magnitude. Peter Smits, ABB’s executive vice president and head of Power Technology Products division explains how ABB will accelerate the schedule: “For our customer, we combine fast equipment delivery and our market leading global manufacturing capabilities with local expertise and resources.” In addition, ABB brings a unique approach to the project through its ability to couple equipment supply with proven project management. “The decisive value is, that ABB is able to bring both manufacturing and implementation together on such a scale,” says Smits.

Although the project calls for well-proven technology, the engineering scope for such a high voltage system is extremely complex. The ABB order encompasses two converter stations for the HVDC system, and includes converter valves, power transformers and smoothing reactors for both the sending and receiving ends of the link. In total, 28 power transformers and the six smoothing reactors will be supplied jointly by ABB’s Transformer factory in Ludvika, Sweden and the Chinese State owned Xi’an transformer works, an ABB licensee.

“This major order for China, our second in two years, provides further evidence of ABB’s intention to support the economic development of China, not just by delivering the most technologically advanced and efficient solutions for its power projects, but also by working in direct partnership with local businesses,” says Peter Smits. “Our strong local presence in this growing market now includes 28 companies and 6,000 employees.”

ABB ( is a global leader in power and automation technologies that enable utility and industry customers to improve performance while lowering their environmental impact. ABB has 160,000 employees in more than 100 countries.
