The HVDC Three Gorges – Changzhou is an 940km (580miles) long bipolar HVDC transmission line in China for the transmission of electric power from the Three Gorges power plant to the area of Changzhou.

The transmission line went into service in 2004. It runs from the static inverter station, Longquan, away from the Three Gorges power plant to the static inverter plant, Zhengping, near Changzhou. The HVDC Three Gorges-Changzhou is a bipolar 500 kV powerline with a maximum transmission power rating of 3,000 megawatts.

A part of the line is the Yangtze River Crossing Wuhu over Yangtze River using 229m (751feet) tall pylons.

The electrode at Chujiahu is also used by HVDC Hubei - Shanghai for grounding.
