At the construction site of the grid type energy storage power station outside the Dongsu Substation in Xilingol League, Inner Mongolia, the last 5MWh energy storage cabinet has completed grid connection debugging, and the blue energy storage array is neatly laid out in the sunshine of the grassland. With the full capacity grid connection of these two projects, the world's largest single grid type lithium iron phosphate independent energy storage power station has officially landed in Ximeng, installing the core stabilizer of a new power system for this region with the highest density of new energy installations in the country.

Large capacity grid energy storage landed in Ximeng

This key project with a total scale of 4GWh, with a total investment of about 3 billion yuan and a total land area of 420 acres, is fully equipped with 800 sets of 5MWh energy storage cabinets independently developed by Star Charging Full Stack. It is expected to be fully operational by the end of August 2026.

After the project is put into operation, it can stably discharge about 1 billion kilowatt hours per year, which can effectively stabilize the intermittent fluctuations of local wind and photovoltaic power. Unlike traditional grid connected energy storage, this grid based system has the core capabilities of active frequency regulation, voltage regulation, and islanding operation. When the power grid fails, it can respond quickly in milliseconds, avoiding the risk of large-scale power outages. By 2026, the installed capacity of new energy in Inner Mongolia has exceeded 180 million kilowatts, and the large-scale implementation of energy storage has directly solved the stability problem of high proportion of new energy grid connection, providing key support for regional energy security and green power consumption.

The advantages of full chain technology support the landing of industries

As the core equipment supplier of the project, Star Charging has accumulated over 12GWh of projects in the domestic user side energy storage track by 2026, building a complete technical system for the coordination of multiple elements such as photovoltaics, energy storage, charging networks, and virtual power plants.

This energy enterprise, established in 2014, relies on its long-term accumulation in the fields of high-power charging, intelligent operation and maintenance, and energy trading to create a mature integrated solution of source grid load storage and charging for factories, computing power centers, and high energy consuming enterprises. At the 2026 Munich International Energy Storage Exhibition, the total scale of energy storage strategic cooperation signed between enterprises and multinational energy companies is nearly 3.5 GWh, and the nearly 1 GWh centralized energy storage order won in India during the same period also marks the official entry of domestic grid based energy storage technology into overseas markets. Keywords: energy storage projects, new energy projects

The 4GWh blue energy storage array spread on the grasslands of Ximeng is not only two energy projects that have landed, but also a landmark achievement of China's technological independence in the field of ultra large capacity grid energy storage. It has proven through practical implementation that domestic energy storage technology can fully support the stable operation of high proportion new energy grids, providing replicable practical samples for the construction of new power systems nationwide and even globally.Editor/Cheng Liting
