On October 30, 2026, the Danfengyuling Pumped Storage Power Station in Shaanxi Province was officially approved by the Shaanxi Provincial Development and Reform Commission, marking a key breakthrough in project construction.

Shaanxi pumped storage adds another million kilowatt level project

This project has been included in the Shaanxi Province's 2024-2028 pumped storage layout optimization and adjustment plan approved by the National Energy Administration. It is a key implementation project of Shaanxi Province's 15th Five Year Plan and the core promotion project of Shaanxi Hydropower in 2026. The power station is located in Danfeng County, Shangluo City, with a straight-line distance of about 135 kilometers from Xi'an City, about 36 kilometers from Shangluo City, and only 10 kilometers from Danfeng County. It has excellent location conditions and convenient external transportation.

The power station is a daily regulated pure pumped storage power station with a total installed capacity of 1.4 million kilowatts, a total investment of 9.609 billion yuan, and a total construction period of 69 months. The main building includes complete supporting facilities such as an upper reservoir, a lower reservoir, a water transmission system, an underground factory building, a switch station, and a flood discharge and sand removal tunnel, and belongs to the first-class (1) type project. Previously, the project had completed all prerequisite approvals such as pre feasibility study review, land pre-approval, and social stability risk assessment, and the approval process was efficiently promoted throughout the entire process.

Significant upgrade of regional power grid regulation capability

After the project is completed and put into operation, it will mainly undertake core functions such as peak shaving, valley filling, energy storage, frequency regulation, phase regulation, and emergency backup of Shaanxi power grid, providing key regulatory support for the high proportion of new energy grid connection in the region. The designed annual power generation of the power station is 2.814 billion kilowatt hours, and the annual pumping capacity is 3.752 billion kilowatt hours, which can significantly stabilize the intermittent fluctuations of wind and solar power generation and enhance the capacity of Shaanxi power grid for the consumption of new energy.

Previously, the feasibility study stage survey and design work of the project has been initiated. In the future, we will accelerate the preparation and review of 14 special reports on environmental impact assessment, water conservation, and access system design, and coordinate the bidding related work. After the project is put into operation, it will directly optimize the energy structure of Shaanxi region, fill the gap of large-scale energy storage and regulation facilities in the hinterland of Guanzhong, and provide solid support for the stable operation of the new power system in Northwest China.Editor/Cheng Liting
