ABB (ABBN:VX) has won an order worth $150m, which will see the Swiss power and automation company supply key equipment to what will be the world’s highest capacity power link when completed in 2014.

China’s 8000 MW, 800 kV ultra high-voltage direct current (UHVDC) Xiluodu-Zhexi interconnector will transport hydroelectric power over a distance of 1670 km, from Yibin in Sichuan province in southwest China to Zhejiang province on the east coast.

ABB`s scope of supply for the project includes converter transformers, DC filter capacitors and key components for the converter valves.

The Xiluodu-Zhexi link will be capable of transmitting the equivalent energy of eight large power plants and supplying 40 TWh of electricity per year, which is enough to meet the needs of over 11m Chinese consumers.

China remains the biggest carbon emitter in the world, so it is interesting to note that because the Xiluodu-Zhexi link will transport power generated by hydroelectricity it is said it will help to avoid the combustion of more than 12mi tonnes of coal, and thereby reduce potential annual carbon emissions by about 34m tonnes.

ABB has a long history of HVDC expertise and operates a state-of-the-art test facility in Switzerland (pictured).
