SGCC awards transmission contracts to ABB in China [free access]

April 9, 2020

Chinese grid company, State Grid Corporation of China (SGCC), has awarded contracts to Switzerland-based ABB to supply advanced high voltage direct current (HVDC) transformers and other HV equipment for three 800 kV ultra HVDC (UHVDC) transmission lines—Shaanxi–Wuhan, Yazhong–Nanchang and Qinghai–Henan. These power lines will facilitate the evacuation of power from various renewable energy (RE) generation plants (wind and solar) in different parts of the country.

 

The 1,100-km-long Shaanxi–Wuhan transmission line starts from the Shanbei convertor station in Fugu county, Yulin city of Shaanxi province to the Wuhan convertor station in Wuhan city, Hubei province, and runs through Shanxi and Henan provinces. It will transmit up to 8 GW of electricity, enough to meet the power needs of 8 million people. The project received National Development and Reform Commission (NDRC) approval in January 2019, with a total investment of CNY17.84 billion.

 

Further, the 1,711-km-long Yazhong–Nanchang (Jiangxi) power line will start from the Liangshan converter station in the Sichuan province and to the Fuzhou converter station in the Jiangxi province, passing through 14 cities in Sichuan, Yunnan, Guizhou, Hunan, and Jiangxi provinces. On completion, the power line will help the hydro-resource-rich Sichuan Province, Southwest China to transmit green energy to the load centre of Jiangxi Province in East China.


The CNY22.6 billion worth, 1,587 km Qinghai–Henan transmission line will extend across four provinces, from northwest China's Qinghai, Gansu and Shaanxi provinces to central China's Henan Province. It will have a rated transmission capacity of 8 GW, with an annual transmission capacity of about 40 TWh. The governments of China's Henan, Qinghai and Gansu provinces signed a cooperation agreement with the SGCC in 2018, for construction of the power line, with expected completion in 2020.
