China's State Grid Corporation officially commenced construction of the Hami-Chongqing ±800 KV Ultra High Voltage Direct Current (UHVDC) project, marking the country's fourth UHVDC project launched this year.
Spanning a distance of 2,290 kilometers, the project originates at the Barikun converter station in Hami city, Xinjiang Uygur autonomous region, and terminates at the Yubei converter station in Chongqing municipality.
This line traverses five provinces - Xinjiang, Gansu, Shaanxi, Sichuan, and Chongqing, covering a 62.4-kilometer stretch within Chongqing.
The project will integrate 10.2 GW of new energy capacity including wind, photovoltaic, and solar thermal, and its new energy power generation is expected to account for over 50% of the total. Additionally, the project will also be connected with a supportive 4 GW coal-fired power capacity, according to Lv Xindong, Deputy General Manager of State Grid Xinjiang Electric Power Company.
Projected to be operational by 2025, the Hami-Chongqing UHVDC project is expected to transmit over 36 TWh of electricity annually from Xinjiang to Chongqing, surpassing one-fifth of the city's total power consumption.
In another significant endeavor, China's State Grid has also initiated the construction of the Chongqing Liziwan Pumped Storage Power Station. With a total investment of $10.3 billion, the power station is expected to further elevate Chongqing's peak power supply capacity after it completes, playing a crucial role in regulating and securing the stability of the southwest power grid.
