Power and automation technology group ABB has won an order worth approximately $120M to engineer and supply key equipment for the Jinping-Sunan 800kV Ultra High Voltage Direct Current (UHVDC) power transmission project which will transport hydropower from Sichuan province in central-western China to the highly industrialized coastal area in the eastern province of Jiangsu.

The system and key equipment will be designed in close cooperation with the project developer State Grid Corporation of China (SGCC) and local Chinese partners, and ABB will also supply key components for both converter stations, including converter valves, the control and protection system and DC yard equipment. ABB has also been selected to supply the 800kV UHVDC transformers for both converter stations.

The 2090km UHVDC link will have a rated capacity of 7200MW, and is expected to be energized in 2013.

“The Jinping-Sunan project reflects the continued confidence of SGCC in ABB’s technologies and globally proven domain expertise in HVDC,” said Peter Leupp, head of ABB’s Power Systems division. “We have a long track record in China and are pleased to continue supporting the country in its efforts to strengthen the national power infrastructure and minimize environmental impact.”
