China’s CSG puts into operation 800 kV UHV DC line [free access]

June 4, 2018

China's grid network developer China Southern Power Grid (CSG) has put into full operation a 1,953-km-long, ultra high voltage direct current (UHV DC) line linking Jianchuan County in Yunnan with Bao’an District of Shenzhen City in Guangdong. The project was partially commissioned in December 2017.

 

The ±800 kV Northwest Yunnan–Guangdong line is one of the biggest lines to be constructed by CSG with a total investment of CNY22 billion. It can transfer about 20 billion kWh power from hydropower plants located on the Lancang River in Yunnan to load centres in Guangdong. The line will help the Pearl River Delta region cut coal consumption by 6.4 million tonnes, and emissions of carbon dioxide and sulphur dioxide by 16 million tonnes and 123,000 tonnes respectively every year.

 

The project is one of the 12 projects that are part of China’s action plan to reduce coal consumption and control air pollution.
