[Explanation] On November 30, the first power station that started construction at the clean energy base in the upper reaches of the Jinsha River——the last unit of Huadian Jinshang Suwalong Hydropower Station was officially put into operation for power generation. So far, all 4 units of Suwalong Hydropower Station have been put into operation.

It is reported that the Jinsha Jiangsu Walong Hydropower Station, located at the junction of Batang County in Sichuan and Mangkang County in Tibet, has a total installed capacity of 1.2 million kilowatts and an average annual power generation of about 5.5 billion kilowatt-hours, which can save 1.8 million tons of standard coal and reduce carbon dioxide emissions by 4.3 million tons .

  A single unit of the Suwalong Hydropower Station has a length of 20 meters, a maximum outer diameter of 16 meters, and a weight of 1,300 tons. The large temperature difference in the plateau area will cause an error of about 0.3 mm during the installation process of the unit, although there are only three The thickness of A4 paper, but if it is not handled properly, it may cause deformation of the stator and rotor of the unit.

  By building insulation sheds on site, combining temperature control with measurement at the same time and place, we "strive for every minute", and the installation quality has reached the leading level of domestic units of the same type.

Under the rated load, the bearing swing of Unit 1 is only 0.05mm, which is thinner than a hair.

  [Explanation] The concept of ecological priority and green development has been well implemented in the construction of Suwalong Hydropower Station.

As of November 2022, a total of 9 times of multiplication and release have been carried out, and a total of 2.1 million rare and unique fish fry have been released. At the same time, a set of "black technology" system for protecting fish has been innovatively established.

  The dual-channel fish passing system of the upward fish lifter and the downward fish collection and transportation system was completed and put into operation before the water storage at the lower gate. It became the first fish lifting machine and fish collection boat combined fish passing system in the Wanli Yangtze River. It will start trial operation in August 2022 , Let the fish pass through the system to complete the upstream and downstream gene exchange.

  [Explanation] At the same time, the Suwalong Hydropower Station accurately targeted poor households in the hub area, submerged area, and affected area of ​​the power station to carry out "three-point training" to enable 15 poor young people to find employment, and Yixilam was one of them.

24-year-old Yeshi Ram has a family member who is seriously ill and needs to be taken care of. The pressure of life makes her relatively introverted.

Through the "three-point training", Yixilam is now engaged in equipment maintenance and defect elimination work in the power station. Through continuous learning, she can also skillfully operate bridge cranes, door cranes and other special equipment.

  Having this stable job and income has also brought a lot of help to my family. While learning some daily work (maintenance and elimination) of mechanical equipment, I also learned the operation of bridge cranes and door cranes. Introverted, now I get along with my colleagues, and my personality has become cheerful.

  [Explanation] Since the construction of the Suwalong Hydropower Station, the living conditions of the people on both sides of the strait have also undergone tremendous changes. Roads have been built, jobs have been provided, education and training have increased the income of the local people through substantial channels.

  During the construction period, we actively recruited more than 400 people and 170 vehicles to participate in the project construction, and 170 people were employed in public welfare positions such as camp security, sanitation and canteen logistics, creating an output value of 140 million yuan for the local area.

Actively improve the local infrastructure construction, build and rebuild 91.7 kilometers of roads, rebuild and rebuild 4 cross-river bridges.

  [Explanation] It is understood that the clean energy base in the upper reaches of the Jinsha River and its supporting Jinshang-Hubei DC transmission project have been included in the "The 14th Five-Year Plan for National Economic and Social Development of the People's Republic of China and the 2035 Long-term Goal Outline", the base After full completion, the annual power generation will reach 140 billion kwh, saving 42 million tons of standard coal and reducing carbon dioxide emissions by 116 million tons.
