| 1 | Before the implementation of west-to-east power transmission project, there is only one transmission line from Tianshengqiao to Guangdong which is still under construction. To complete the task of sending 10 million kilowatts to Guangdong, the construction of the power transmission project was a highlight and involved cross-provincial coordination. Tianshengqiao-Guangzhou ± 500 kV DC power transmission project The project from Guizhou Tianshengqiao converter station to Guangdong Converter Station in Guangzhou has a total length of 960 kilometers and a transmission capacity of 1.8 million kilowatts.

The total transmission capability of the west-to-east power transmission project has exceeded 5 million kilowatts. Three Gorges—Guangdong ± 500kV DC power transmission project(invested and constructed by State Grid Corporation of China). The project starts from Jiangling converter station in Jingzhou, Hubei Province, and ends at echeng converter station in Huizhou, Guangdong Province. The total length of the transmission line is 962 km with a transformation capacity of 3 million KVA. The project was put into operation in January 2004 in unipolar mode, and in June 2004 in bipolar mode, increasing the transmission capacity to Guangdong by 3 million kilowatts. (5) Guizhou-Guangdong ± 500kV DC power transmission project The project starts from Anshun convertor station in Guizhou Province and ends at Zhaoqing convertor station in Guangdong Province. The total length of the transmission line is 882 km with a transformation capacity of 3 million KVA. The project is planned to be put into operation in January 2004 in unipolar mode, and in June 2004 in bipolar mode, increasing the transmission capacity to Guangdong by 3 million kilowatts. The project is planned to be put into operation in June 2005 and actually in September 2004 in bipolar mode, and will increase the transmission capacity to Guangdong by 3 million kilowatts. |
