Gezhouba Shanghai

The first HVDC power transmission in China was built to connect the 2,715 MW Gezhouba hydropower generating plant near Yichang on the Yangtze River with the city of Shanghai

Work on the Gezhouba hydroelectric project began in 1970, and was completed in 1988. A key water-control facility and an important component of the Three Gorges project, the Gezhouba hydropower station is located at the lower end of the Three Gorges in the suburbs of Yichang, 38 km downstream. It was China’s largest hydroelectric facility until the completion of Three Gorges, and was the first structure to block the flow of the Yangtze River.

In 1985, Hitachi Energy -in a consortium with Siemens - received the contract to build an HVDC transmission system between Gezhouba and Nanqiao District, near Shanghai from The State Power Corporation, China.

Commissioned in 1989, the bipolar 1,046-km Gezhouba - Shanghai  HVDC transmission link is rated at 500 kV, with maximum power capacity of 1,200 MW.
