On October 4, 2022, the EPC general contract project of the 200,000 kW photovoltaic sand control base in Liangzhou District, Wuwei City, Gansu Province, jointly constructed by the Seventh Hydropower Bureau of China and the Northwest Institute, started pile test construction.

The project is located in Tengger Desert, east of Jiudun Town, Liangzhou District, Wuwei City, covering an area of 6,488 mu, including 4,776 mu of photovoltaic area and 1,776 mu of sand control area. The average altitude of the project is 1,490 meters, which is an aeolian dune area with large terrain fluctuation and maximum height difference of 38.19 meters. The construction period of the project is 283 days. Since the project officially started on September 20th, the project department has advanced deployment, optimized resource allocation, completed the field level of more than 1520 mu, and started the pile test construction in advance by optimizing the design scheme.

Liangzhou District 200,000kW photovoltaic sand control base project is the first batch of national large base photovoltaic projects in line with the national carbon peak, carbon neutral, "double carbon target", and is also the first photovoltaic sand control base project of the seventh Bureau of Hydropower. The project combines the development of solar energy with the management of the Tengger desert, and makes use of the desert to generate "gold", which can contribute at least 380 million KWH of clean electricity every year, so as to achieve both ecological and economic benefits.
