World’s Largest and Most Advanced 1000kV UHV Substation Put into Operation

HIMALAYAL - SHANGHAI - CHINA

The world’s largest and most advanced UHV substation was officially put into operation in the city of Tianjin on Jan 12, 2017. The electric power from two UHV channels converges and is transmitted to the cities of Beijing and Tianjin and Hebei province. 

With 1000kV UHV substation connects two HUV channels from Inner Mongolia and can annually provide another 20 billion kilowatt hours of electricity for the city of Tianjin, which amounts to one third of total electricity consumption of Tianjin. 



According to Wang Cheng, deputy director of communication and construction department of SGCC, the proportion of electric power transmitted from other provinces to the city of Tianjin grows from 20% to 35%, which amounts to a cut of 9 million tons of annual coal consumption. What is more, the emissions of CO2, SO2 and atmospheric dust can be greatly reduced.  

The two UHV channels - Ximeng-to-Shandong and Mengxi-to-Southern Tianjin connected via the substation are among twelve transmission channels of Action Plan for the Control of Air Pollution. To date, of 12 channels, 4 channels have been put into operation and the rest would have been in service by the end of 2017.
