On June 10, the Hami-Chongqing ±800 kV UHV DC transmission project was put into operation. It is understood that this UHV project is China's first UHV DC transmission project for transmitting new energy from a desert, Gobi, and desolate land base, and it is also the first UHV DC receiving project in south-west China. The project starts from the Balikun Converter Station in Hami City, Xinjiang Uyghur Autonomous Region, passes through Gansu, Shaanxi, and Sichuan, and ends at the Yubei Converter Station in Yubei District, Chongqing. It adopts the "double 800" UHV DC transmission technology with a rated voltage of ±800 kV and a rated capacity of 8 million kW. The transmission distance is 2,260 kilometers, with a total investment of 28.6 billion yuan. As one of China's first large-scale new energy transmission projects from desert, Gobi, and desolate land bases, the project is supported by a 14.2 million kW power supply located in the Gobi base at the northern foot of the Tianshan Mountains in Xinjiang. The installed capacity of wind power, PV, and solar thermal power reaches 10.2 million kW, with new energy installations accounting for over 70%.
