HVDC Tian–Guang is a bipolar 500 kV HVDC system used for transmitting power generated at Tianshengqiao Hydroelectric Plant to Guangzhou. HVDC Tian–Guan, which was built by Siemens and inaugurated in 2001 is capable of transmitting a maximum power of 1,800 MW. The terminals are situated at Tianshengqiao Hydroelectric Plant 2 at 24.91556°N, 105.09639°W and at Beijiao at 23.31611°N, 113.25139°W near Guangzhou. There is a parallel running AC powerline via Pingguo, Laibin, Wuzhou and Luodong, but the DC line helps damping oscillations and stabilizing the system.
