China energizes world’s biggest ultra-high voltage line
State Grid Corporation of China (SGCC) has started up the 1,100-kV direct-current Changji-to-Guquan project, the world’s longest and most-powerful ultra-high voltage power line which will deliver power from China’s far northwest to the heavily populated east.
The $5.9 billion project, which the company refers to as the “Power Silk Road”, stretches 3,293 kilometres, reports Bloomberg.
First approved in December 2015, the new line is able to transmit 12 GW of power. It runs through Gansu, Ningxia, Shaanxi and Henan provinces before ending in the Anhui province city of Xuancheng.
It can supply 66 billion kWh of electricity to eastern China annually, meeting power demand of 50 million households, State Grid said.
