On May 31, 2020, the State Grid issued an announcement that with the completion of the Shaanxi section of the Qinghai-Henan ±800 kV UHV DC transmission project, the entire project was completed.

The Qinghai-Henan ±800 kV UHV DC project is a key project for State Grid Corporation of China to implement General Secretary Xi Jinping’s ecological civilization thought and the spirit of the important speech when inspecting Qinghai. The UHV channel is also a major innovation in China's development of using UHV transmission technology to promote the large-scale development and utilization of new energy, which will further enhance the safety, reliability and standardization of UHV transmission.

The project starts in Hainan Prefecture, Qinghai Province, and ends in Zhumadian City, Henan Province. It passes through 4 provinces, Qinghai, Gansu, Shaanxi, and Henan. The total length of the line is 1587 kilometers. Two new converter stations are built. It will deliver 40 billion kilowatt-hours of clean electricity and is expected to be fully operational in December this year. The project will directly drive investment in related industries by more than 200 billion yuan and provide nearly 10,000 jobs. It will play a positive role in stabilizing employment, stabilizing investment and protecting people's livelihood. It has significant economic, social and environmental benefits and is a real benefit along the route. The masses benefit the "electric power road" of the people's livelihood in the four provinces.

The headquarter of State Grid Co., Ltd. set up a construction coordination and supervision group, and the State Grid UHV Department sent people to the site to supervise the battles and make every effort to ensure the smooth completion of the project construction goals. State Grid Qinghai and Gansu Electric Power have overcome the difficulties of construction and transportation, the difficulty of construction, the extremely harsh climate, and the fragile ecological environment. They have established green environmental protection construction concepts, increased investment in environmental protection and soil and water conservation, and paved steel plates in temporary roads and machinery docking areas. Ensure green construction to the greatest extent. State Grid Shaanxi Electric Power strengthens the organization and management of the project through "monthly tasks, weekly plans, and daily pre-control", refines the tasks to the tower position and the line release section, and insists on issuing tough lists every month, weekly coordination and supervision, and daily plan correction. , Successively breaking through the difficulties and constraints in the construction process. State Grid Henan Electric Power has increased investment in construction power, increased operating area, optimized key processes, implemented mechanization and large-scale water flow operations, strictly implemented safe and civilized construction measures, and managed and controlled the risk of on-site operations.

During the construction process, the project vigorously advocated "inheriting the red gene, protecting the green ecology, and casting the golden quality". The project temporary party branch and 6 special temporary party branches were established to include all party members of the participating units, especially the subcontracted party members The Party General Branch is under unified management, carrying out a series of themed Party Day activities, giving full play to the role of the party branch as a fighting fortress and the exemplary role of party members as pioneers, and making every effort to create a model project for the new era.

State Grid has a relationship with China's energy development prospects. Are you aware of the central enterprises that are based on everyone's vital interests? Editor/Peng Xue
