recently, Gansu Yumen 200MW/800MWh independent shared energy storage power station constructed by EPC of Guizhou engineering company was successfully electrified.

the project is located in qingquan township, Yumen city, Gansu province. as the company's largest energy storage project at present, the project has a construction scale of 200MW/800MWh, 160 5MWh battery cabins, 40 5MWPCS booster cabins and a 330 kv booster station.

Since the start of the project, it has faced severe natural environment tests such as high temperature in summer, severe cold in winter, sandstorms and complex geology, and the construction is very difficult. The project department has set up three vanguard teams, namely, "Party member commando", "worker pioneer" and "youth commando". With a high sense of responsibility and mission, the project department has scientifically coordinated and accurately implemented policies, went deep into the front line of the project, dynamically optimized the construction scheme, innovatively applied two core construction technologies, namely, concrete foundation chamfering technology and angle steel finished protective sleeve, according to the characteristics of Gobi environment, so as to effectively disperse temperature stress and provide a fitting surface, significantly improves the durability and maintenance of the infrastructure. At the same time, we should strengthen the connection between resource allocation and working procedures, strengthen the application of digital intelligence construction platform, and build a solid defense line for project safety. Under the rigid constraint of "no lag in progress and no discount in quality", we have successfully overcome the construction problems and realized electrification on schedule.

The successful electrification of the project will greatly improve the local new energy consumption level and the peak shaving capacity of the power grid, enhance the reliability of power supply and the security and stability of the power grid, help green and low-carbon development, and promote the optimization of the local energy structure. Drive the development of related industries and increase employment and income, and provide solid green support for local economic and social high-quality development, ecological environment protection and people's livelihood power protection.
