China News Service, Urumqi, March 27th (Shi Yujiang Miao Wenqin) drove up the steep mountain road, and under the blue sky, the mountains dotted with white snow were particularly magnificent.
"Today is really a rare good weather. The day before yesterday, it was snowing heavily here, and the mountains were covered in silver." The driver of the car told a reporter from Chinanews.com.

On the 26th, the site of the pumped storage project in Fukang City, Xinjiang was very lively, with colorful flags, fireworks and cheers coming one after another.
On the top of the towering mountains, in the valleys surrounded by mountains, a huge dam has been capped.
"This is the upper reservoir dam of the first pumped storage power station under construction in Xinjiang, and it is also the first pumped storage power station in my country that adopts the design-led EPC construction management model." State Grid Xinyuan Xinjiang Fukang Pumped Storage Co., Ltd. Fu Bailing, general manager and deputy secretary of the party committee, said that the dam crest is 2275m high and the maximum dam height is 133m.
The whole project has gone through 37 months. The participating units have overcome the difficulties of high altitude, severe cold weather, and narrow terrain construction by adding large-scale equipment and investing in technical personnel with rich experience.
Looking around the upper reservoir dam, there are mountains on three sides.
Looking up from the mountainside, the upper reservoir is like being held up by the mountains.
"In the period of low electricity consumption, the reversible pump-turbine unit is used to pump the rich electric energy of the grid through the lower reservoir, and the potential energy is converted into water and stored in the upper reservoir to realize the 'charging' function. During the peak of electricity consumption, water is delivered from the upper reservoir. The pipeline goes straight down, and the potential energy of the water is converted into electrical energy through the hydro-generator to realize the 'discharge' function." Fu Bailing introduced.

The pumped storage power station includes upper reservoir, lower reservoir, water delivery system, underground powerhouse and ground switch station.
At present, the upper and lower dams and reservoirs have been fully formed, and the underground power plant is being constructed in an orderly manner.
Driving along the cave into the hinterland of Tianshan about 1 kilometer, you can see the prototype of a huge underground power station. Workers are constructing in an orderly manner, pouring the outer concrete of the volute of the No. 1 generator set, and the concrete of the base of the remaining three volutes is under construction. sequence construction.
A reporter from Chinanews.com noticed that the underground powerhouse system in the mountain is centered on the main powerhouse tunnel, the main transformer tunnel, and the tail gate tunnel, which are arranged in parallel from upstream to downstream.
Inside the mountain, workers are working on the generator set in a tense and orderly manner.

Why spend time and effort building a pumped-storage power station?
It actually acts as a "charging treasure" for the power system.
"When the power system is in surplus, the power station uses the power to pump water to a high place for storage; when the power is insufficient, it releases water to generate electricity to meet the needs of production and living." State Grid Xinyuan Xinjiang Fukang Pumped Storage Co., Ltd. Chairman and Secretary of the Party Committee Yan Liangping said that the power station is a daily regulation pure pumped storage power station. After the operation is integrated into the power grid, it undertakes tasks such as peak regulation, frequency regulation, phase regulation, energy storage, system backup and black start, which can increase the consumption of new energy power and optimize the power supply. structure.
A reporter from Chinanews.com learned that pumped storage power stations have been operating abroad for more than 100 years, and my country has only entered a stage of rapid development in the early 21st century.
"After the completion of the Fukang pumped-storage power station, it can further improve the power supply structure of Xinjiang and northwest power grids, ease the pressure on power grid peak regulation, enhance the safety and reliability of power system operation, and promote the large-scale development of green energy and help energy 'dual control'. It is of great significance to achieve the carbon neutralization goal of peaking carbon." Yan Liangping said.
