Chinese provinces sign agreement for Qinghai–Henan UHV project [free access]

November 1, 2018

The governments of China's Henan, Qinghai and Gansu provinces have signed a cooperation agreement in Beijing with the State Grid Corporation of China (SGCC) to build an ultra-high-voltage (UHV) clean power transmission line from Qinghai to Henan.

 

The project will start construction in November this year and is expected to become operational in July 2020. It is the world's first renewable energy, high voltage, power transmission project, and mainly transmits renewable power generated in Qinghai and Gansu.

 

Under the project, a ±800 kV direct current (DC) transmission line will extend 1,587 km across four provinces, from northwest China's Qinghai, Gansu and Shaanxi provinces to central China's Henan Province. It would have a rated transmission capacity of 8 million kW, with an annual transmission capacity of about 40 billion kWh.
