ZHENGZHOU, Dec. 1 (Xinhua) -- Power supply in central China will be further improved with the operation of a 1000-kV ultra-high-voltage alternating current (UHVAC) power transmission line on November 26.
With a total investment of 3.8 billion yuan, the 281-kilometer-long project starts from the Yunan converter station in Henan’s Zhumadian city and ends at the Wuhan converter station in Hubei Province. It adopts world-leading ultra-high voltage transmission technology, featuring advantages such as large transmission capacity, low losses in power transmission, and land-saving, said a manager with the State Grid Henan Electric Power Company.
The project is an important part of the central China’s UHV grid network, which facilitates wind, solar, hydropower, and thermal power transmission and distribution between Hubei, Henan, Jiangxi, and Hunan provinces in central China, and meet the growing electricity demand in the region during the 14th Five-Year Plan period (2021-2025).
As China’s primary grid operator, State Grid Corporation of China has built a total of 34 UHV projects, with a UHV DC cross-regional power transmission capacity of 130 million kilowatts. It has initially established a backbone UHV AC grid network in eastern, northern and central China, which ensures safe and reliable supply of electricity and support energy structure transformation in China.
