[Explanation] On December 4, the Tibet-Ali and Tibet-China Power Grid Interconnection Project (hereinafter referred to as: Ali Interconnection Project) was officially put into operation. China’s last prefecture-level administrative region was officially connected to the national large grid, ending the operation of the Ali Grid’s isolated grid history.
According to Yi Jianshan, the executive deputy commander of the Alibaba Networking Project Headquarters, it only took 14 months for the Alibaba Networking Project to start and put it into operation, creating a miracle of power construction.
At the same time, in the process of project construction, actively carry out technological innovation, overcome technical difficulties, and effectively reduce the impact of construction on the plateau wetland environment.

We deepened scientific and technological innovation in the process of project construction and implemented key technologies for spiral anchor foundations in high-altitude swamps, reducing the excavation volume of each tower foundation from more than 500 cubic meters to 109 cubic meters, effectively reducing the impact on the plateau wetland environment.
[Explanation] On the same day, the reporter learned from the State Grid Corporation of China that the Alibaba networking project was started in September 2019 with a total investment of RMB 7.4 billion.
The project starts in Sangzhuzi District, Xigaze City, and ends in Gar County, Ngari Prefecture. The total length of the transmission line is 1,689 kilometers. It is the 500 kV power transmission and transformation project with the highest altitude and the longest distance in the world.
In addition, the Ali network project was completed and put into operation to solve and improve the safe and reliable power supply of 380,000 farmers and herdsmen in 16 counties along the project. Tibet has also entered the main power grid covering 7 cities and 74 counties (districts). ) A new era of unified power grid.
