recently, Wuwei huajing pilot 300MW/1200MWh independent energy storage power station project, located in jiudun beach photovoltaic sand control demonstration park in Liangzhou district, was announced to be successfully connected to the grid, marking a solid step forward in building a new power system, promoting green and low-carbon energy transformation and promoting industrial chain supplement chain extension, and also providing key technical support for local power grid peak regulation, new energy consumption and new power system construction.
Zhang Tao, project manager of 300MW/1200MWh independent energy storage power station of Wuwei huajing pilot power co., ltd., told reporters:” 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. With the strong support of the municipal and district governments and the power grid, the project was successfully connected to the grid on March 31, 2026. Currently, commissioning of the energy storage area and the subsequent grid-connection tests are underway in full swing. Commercial operation is scheduled to be completed by April 30, 2026.
walked into the independent energy storage power station project site, a huge buzzer sounded through the ears, and rows of white battery cabins stood neatly in the park, equivalent to a huge power” reservoir “. “Green electricity” generated by the sprawling array of photovoltaic panels across the vast desert is collected via high-voltage transmission lines and stored in 240 energy-storage batteries. During peak demand periods, the stored energy is discharged to smooth out fluctuations in the power supply, thereby enabling peak-shaving for renewable energy. Staff members moved swiftly between the equipment, meticulously monitoring all operating parameters to ensure full readiness for the upcoming series of commissioning tests.
it is understood that the project covers an area of 98.43 mu and has a total investment of 1.368 billion yuan. the project includes 60 sets of 5MW/20MWh energy storage units, each of which consists of 1 set of 5MW PCS boost converter 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 cells are lithium iron phosphate (LFP) batteries, designed for a 20-year operational lifespan with a cycle life of no fewer than 6,000 cycles.
After the project is officially put into operation, it will accept the unified dispatch of Gansu power grid, which is mainly used for power grid peak regulation and frequency regulation, emergency standby power supply and other auxiliary services, which will greatly improve the allocation space of new energy power generation and play a positive role in promoting the consumption of new energy in the region, reducing the load pressure of the power grid, maintaining the stable operation of the power grid and helping to ensure 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.
Zhang Tao, project manager of 300MW/1200MWh independent energy storage power station of Wuwei huajing pilot power co., ltd., said: “as the largest independent energy storage power station project in Wuwei city, the completion of the project is of great significance to the realization of high-quality development of new energy storage in the whole province, and can effectively alleviate the peak shaving pressure brought by the rapid development of new energy in the whole province.”
the new energy storage is an important way to achieve the goal of carbon neutralization and an important support for energy transformation. The 300 MW/1,200 MWh standalone energy storage power station project of Wuwei Huajing Linghang Power Co., Ltd. has successfully been connected to the grid. This will effectively enhance the power system’s supply reliability and grid regulation capabilities, while significantly improving the quality of new energy generation integration.
