Crossing the Heitu Mountain Pass at an altitude of 4300 meters, you will arrive at Lajia Town, Maqin County, Golog Tibetan Autonomous Prefecture, Qinghai Province. The red gravel rock mountain ranges one after another, and the Yellow River twists and turns with the mountain terrain between the plateau canyons. The highest elevation and largest installed hydropower station under construction in the upper reaches of the Yellow River, the Qinghai Ma'erdu Hydropower Station of the National Energy Group, is located here.

The total installed capacity of the National Energy Group Qinghai Ma'erdu Hydropower Station is 2.32 million kilowatts, located on the main stream of the Yellow River at the junction of Tongde County and Maqin County in Hainan Tibetan Autonomous Prefecture, Qinghai Province. It is the backbone power supply point for the implementation of the "West East Power Transmission" and "Green Power into Henan" by the country.

The Marduan Hydropower Station is expected to achieve the first unit put into operation for power generation in March 2024, and all units will be put into operation for power generation in December 2024. After the power station is fully put into operation, it is expected that the average annual power generation will be 7.304 billion kilowatt hours, making it an important clean energy export project in Qinghai Province.

At the construction site of the main dam of the Mahogang Hydropower Station, large pure electric mining trucks are transporting stones for the dam filling. According to Wang Haitao, Director of the Infrastructure Construction Management Center of the Mahogang Hydropower Station, currently 55 pure electric mining vehicles have been put into use at the project site to undertake the construction task of dam filling. Compared with traditional fuel mining vehicles, pure electric mining vehicles achieve significant energy conservation while improving operating efficiency by more than 30%.

Dust prevention equipment and measures are distributed throughout the construction site, and equipment and facilities such as fog guns, sprinkler trucks, and sprinkler systems have been purchased with over 30 million yuan invested; Qinghai spruce and poplar trees arranged neatly from the entrance of the construction site to the roads inside the site; The concept of maintaining ecosystem stability is reflected everywhere in the release stations and fish lift machines that promote fish proliferation

The Wanli Yellow River is the mother river of the Chinese nation, and the Guoluo Tibetan Autonomous Prefecture is an important source of water conservation and supply in the upper reaches of the Yellow River. Transforming the surging Yellow River water into green electricity that illuminates the lights of the world, clean energy is becoming an important force in promoting green development in the upper reaches of the Yellow River.

The picture shows the lifting site of the turbine runner of the first unit of the National Energy Group's Qinghai Mahogan Hydropower Station on September 27th.

At around 14:00 on September 27th, with the waving of a command post and flag, the turbine runner of the first unit of Mahogan Hydropower Station slowly rose under the traction of the main powerhouse bridge crane. After nearly an hour of lifting operation, it accurately reached the predetermined position and the lifting was successfully completed.

The diameter of the turbine runner of the Mahogan Hydropower Station is 6.6 meters, the height is 3.1 meters, and the total weight is 158.5 tons. It is assembled and welded from the upper crown, lower ring, and 17 blades. After the hoisting of the turbine runner of the first unit of the Mahogan Hydropower Station is completed, the unit will enter the final assembly stage of the turbine, laying the foundation for the production and power generation of the first unit in 2024.

During the Mid Autumn Festival National Day holiday, the construction site of the power station was bustling with tower cranes waving giant arms and transportation vehicles shuttling back and forth. We, nearly 5000 builders, have overcome difficulties such as high altitude, hypoxia, and reduced efficiency of artificial equipment, focusing on key parts and links, reversing the construction period, and fighting on the wall. "Li Hongxin, Deputy General Manager of Guoneng Qinghai Yellow River Ma'ergan Hydropower Development Co., Ltd., said that they are fully promoting the construction process of Ma'ergan hydropower station project by focusing on progress, ensuring quality, and promoting safety.
