China Southern Power Grid Company is set to build an 800-kv extrahigh-tension direct current transmission line, which is expected to be in full operation by 2010.
Sources from the company said the transmission line will span the provinces of Yunnan and Guangzhou in south China, with designed transmission capacity hitting between 5 million kw and 6.4 million kw.
The extrahigh-tension transmission project is suitable for long-distance electricity transmission which can reach as far as 2,000 km, the company said.
The China Southern Power Grid Company mainly covers the southern provinces of Yunnan, Guizhou, Hainan, Guangdong and Guangxi Zhuang Autonomous Region, which are expected to consume 434.4 billion kwh of electricity in 2005, about 1.89 times that of the year 2000.
To meet the rising demand for electricity in the southern regions, the company plans to develop a huge power grid network with 8 alternating and 5direct current transmission passages by the year 2010.
In addition, the China Southern Power Grid Company will also provide Vietnam with annual electricity supply of 1.3 billion kwh in a purchase term of ten years starting from January 2007, the company said.
