Zhang Tao, project manager of 300MW/1200MWh independent energy storage power station of Wuwei huajing pilot power co., ltd., said: “the 300MW/1200MWh independent energy storage power station project in Liangzhou district of Wuwei city is invested and constructed by Wuwei huajing pilot power co., ltd. The project started construction on August 1, 2025 and was successfully connected to the grid on March 31, 2026. At present, the commissioning of the energy storage zone and the following network-related test work are being carried out in full swing, and commercial use is planned to be completed by April 30, 2026.”

walked into the independent energy storage power station project site, the huge buzzer sounded through the ears, and rows of white battery cabins stood neatly in the park, equivalent to a huge power “reservoir”. The “green electricity” generated from the scattered photovoltaic panels in the vast desert is concentrated into these 240 energy storage batteries through high-voltage wires, and then released during the peak period to realize the peak regulation of green electricity. The staff shuttled between the equipment, nervously checking the operating parameters, and making full preparations for the next series of debugging work.
it is understood that the project covers an area of 98.43 mu with a total investment of 1.368 billion million yuan. the project includes 60 sets of 5MW/20MWh energy storage units, each set of 5MW/20MWh energy storage units consists of 1 set of 5MW PCS boost converter module and 4 sets of 5MWh energy storage battery containers. The project uses 12 circuits of 35 kV collection lines to connect to the 35 kV side of the newly-built 330 kV energy storage booster station, and synchronously support electrical equipment such as transformers, HGIS, lightning arresters, high-voltage switch cabinets, SVG cabinets, communication cabinets, and auxiliary equipment such as lighting, ventilation, pump gates, etc. The battery core adopts lithium iron phosphate battery, with a designed operating life of 20 years and a cycle number of not less than 6000 times. After the project is officially put into operation, it will accept the unified dispatching of Gansu power grid, which is mainly used for power grid peak regulation and frequency modulation, emergency backup power supply and other auxiliary services, which will greatly enhance the allocation space of new energy power generation, play a positive role in promoting regional new energy consumption, reducing power grid load pressure, maintaining stable operation of power grid and helping energy supply, At the same time, it also provides important demonstration and practical support for building a clean, low-carbon, safe and efficient modern energy system.
“As the largest independent energy storage power station project in Wuwei City, the completion of the project is of great significance to the province’s high-quality development of new energy storage, and can effectively alleviate the pressure of peak shaving brought about by the rapid development of new energy in the province.” Zhang Tao said.
The new type of energy storage is an important way to achieve the goal of carbon neutralization, and it is also an important support for achieving energy transformation. The successful grid-connection of the 300MW/1200MWh independent energy storage power station project of Wuwei Huajing Pilot Power Co., Ltd. will effectively improve the reliability of power supply and grid regulation capacity of the power system, and significantly improve the grid-connected quality of new energy power generation.
