ABB has won orders worth over $300 million to supply breakthrough technologies for the world’s first 1,100 kilovolt (kV) ultra-high-voltage direct current (UHVDC) transmission link. The orders were booked in the second quarter of 2016.
The Changji-Guquan UHVDC link will transmit power from the Xinjiang region in the Northwest, to Anhui province in eastern China and will set a new world record in terms of voltage level, transmission capacity and distance. It will be capable of transporting 12,000 megawatts of electricity - the equivalent of 12 large power plants, a 50 percent increase in transmission capacity, compared with the 800 kV UHVDC links currently in operation. This will also help extend the transmission distance from around 2,000 kilometers (km) to over 3,000 km and play a key role in integrating remote renewables on a large scale, transmitting power over greater distances and facilitating a more interconnected grid.
