Recently, a bidding announcement was quietly launched on the Three Gorges Group's electronic procurement platform. The survey and design services for the bidding design and construction drawing design phase of the Dabancheng Pumped Storage Power Station in Xinjiang have been officially launched for online search. This means that this super power bank, which has been dormant at the foot of the Tianshan Mountains for several years, has finally closed the last door before starting construction after passing through various levels of obstacles such as feasibility study, environmental impact assessment, and approval.

The feasibility study and environmental impact assessment have been passed consecutively

Opening the project schedule, the timeline is clear and tight. In April 2024, the feasibility study report prepared by Yangtze River Design Group was reviewed by the Water and Electricity Institute, and the technical route was granted a pass. In November of the same year, the soil and water conservation plan was approved; In December, the project was officially approved by the Development and Reform Commission of the autonomous region, with a total investment of 10.713 billion yuan locked in. By March 2025, the environmental impact assessment report will be approved, and all prerequisite documents will be collected.

1.4 million kilowatts peak shaving Tianshan

The power station is located in Dabancheng District, Urumqi, about 85 kilometers away from the city center, with a planned installed capacity of 1.4 million kilowatts and four 350000 kilowatt reversible units. The designed annual power generation is 1.983 billion kilowatt hours, and the annual pumping capacity is 2.644 billion kilowatt hours. The regulating capacity of the upper reservoir is 7.71 million cubic meters, the lower reservoir is 7.7 million cubic meters, and the rated head is 520 meters. After completion, it will specialize in peak shaving and valley filling, energy storage and frequency regulation of the Xinjiang power grid, and convert fluctuating wind and photovoltaic power into stable and controllable high-quality electricity.

Changjiang Design Leading Tendering Bureau

The preliminary feasibility study survey has been carried out by Yangtze River Design Group, and this bidding design and construction drawing design section has obvious advantages as the main venue. But there are only a few power design institutes in China that have the ability to design the entire stage of pumped storage, and Electric Power Construction East China Institute, Northwest Institute, and others are also eyeing it. The bidding deadline is set for April 20, 2026, and the answer to who will win the design rights for this billion dollar project is about to be revealed. No matter who the flowers fall on, the mechanical roar at the foot of the Tianshan Mountains has entered the countdown.Editor/Gao Xue
