State Grid Shizuishan Power Supply Company has completed grid-connected energy storage projects in Ningxia, China. Last week, the 220 kV bus sectional transformation at the Xiangyang Substation was completed, allowing the connection of two large energy storage projects, Jianbi and Yuanzhishan Energy Storage Power Stations. Each station has a capacity of 400,000 kilowatts.
The energy storage projects were connected to the grid one year ahead of schedule. The new infrastructure includes two 220-kilovolt outlet intervals, which provide 200,000 kilowatts of grid capacity for each project. Energy storage facilities like Jianbi and Yuanzhishan help regulate the power grid, stabilize fluctuations, and enable the integration of more renewable energy into the system.
In addition to these projects, the State Grid Shizuishan Power Supply Company completed three other energy storage projects in just three months, Zhonghe Sharing, Simplified Energy Storage Project, and Yuanzhishan Energy Storage Project. Together, these developments support a combined energy storage capacity of 600,000 kilowatts.
Energy storage systems play a critical role in balancing supply and demand, especially when renewable sources like solar and wind generate variable power. By integrating energy storage, China aims to improve the consumption of renewable energy locally and ensure stable power delivery.
In recent years, China has also launched several renewable energy projects. One example is the Tengger Desert Solar Park in Ningxia, which has an installed capacity of over 1.5 GW and is one of the largest solar projects in the world. Another is the Jiuquan Wind Power Base, located in Gansu Province, with a planned capacity of 20 GW, making it one of the largest wind farms globally.
