A strategic project that will profoundly change the national energy landscape has officially begun construction in the vast deserts, Gobi and desert areas of western China. On November 27, 2025, the largest and highest proportion of new energy in China's "Shagehuang" large-scale power base project - the Qinghai Hainan Clean Energy Transmission Base Power Project - held a grand groundbreaking ceremony in Xining City, Qinghai Province. This super project with a total investment of nearly 73 billion yuan not only marks significant progress in the construction of large-scale wind and solar bases in deserts, Gobi, and desert areas in China, but also signifies a new stage of large-scale development in the construction of China's new power system.

The total installed capacity of the project reaches 19.44 million kilowatts, of which the proportion of new energy installed capacity is 86.4%, including 9.6 million kilowatts of photovoltaic power, 6 million kilowatts of wind power, and 2.64 million kilowatts of coal-fired power and 1.2 million kilowatts/4-hour electrochemical energy storage system. By constructing one ± 800 kV high-voltage direct current transmission channel with a transmission capacity of 8 million kilowatts, clean electricity can be transmitted directly across thousands of miles to Guangdong. This large-scale energy project fully utilizes the abundant wind and solar resources in the "Shage Desert" area, transforming the resource advantages of the western region into clean electricity advantages, and achieving cross regional optimization configuration through ultra-high voltage transmission technology.

After the completion of the project, it is expected that the annual power generation will reach 36 billion kilowatt hours, which is equivalent to saving about 10 million tons of standard coal and reducing carbon dioxide emissions by about 23.5 million tons per year. Through this' Green Power Expressway ', 36 billion kilowatt hours of clean electricity will be transmitted annually to the Guangdong Hong Kong Macao Greater Bay Area. This not only provides strong green energy support for the economic and social development of the Greater Bay Area, but also has a profound impact on optimizing the national energy layout and promoting coordinated development between the east and the west.

As a landmark project in the construction of a new power system, the implementation of this project will further promote the transformation and upgrading of China's energy structure, make important contributions to achieving carbon peak and carbon neutrality goals, and demonstrate China's responsibility in the global energy transformation process.
