In 2022, Ningxia's grid connected energy storage capacity reached nearly 1 million kilowatts, ranking second in the country, and the development of energy storage entered a "fast lane". The reporter learned from State Grid Ningxia Electric Power Co., Ltd. that the company is based on its advantages in energy resources, fully serving the overall development of low-carbon energy transformation in Ningxia Hui Autonomous Region, and actively promoting the construction of energy storage power stations.

Recently, State Grid Ningxia Electric Power Co., Ltd. completed the preliminary review of the access system report for the Lingwu No.1 Energy Storage Project of China Guanghe Nuclear Power Group Co., Ltd. We have proposed phased access plans based on the construction plan of energy storage projects and the regional power grid access capacity, ensuring the needs of regional users to access the power grid and ensuring the 'first level' of safe and stable operation of the power grid. "Ma Jun, Deputy Chief Engineer of the Dispatching and Control Center of State Grid Ningxia Electric Power Co., Ltd., introduced that as of now, there are 15 grid connected energy storage power stations in Ningxia, with the grid side energy storage capacity ranking first in the country, It is expected that the energy storage scale will exceed 3 million kilowatts by 2023, and the installed capacity of energy storage will exceed 5 million kilowatts by the end of the 14th Five Year Plan.

As new energy gradually becomes the mainstay of power supply, the balance of system power and energy consumption and clean energy consumption will face more challenges. Developing clean energy is a firm choice to achieve the 'dual carbon' goal. With the rapid development of new energy in Ningxia, the development situation requires an increase in energy storage construction. "Yao Bo, Director of the Energy Development Department of the Ningxia Hui Autonomous Region Development and Reform Commission, pointed out that building energy storage power stations is equivalent to adding a large" charging bank "to the power grid. By using the principle of" peak shaving and valley filling "regulation, it can not only alleviate the pressure of peak power supply in the power grid, Improving regional power supply and grid peak shaving capacity, while also achieving dynamic supply-demand balance, providing frequency and voltage regulation auxiliary services, effectively solving the problem of new energy consumption.

Next, State Grid Ningxia Electric Power Co., Ltd. will provide more accurate information on the layout of energy storage projects, conduct a rolling analysis of the total energy storage scale and configuration types year by year, increase forward-looking research, and actively strive to take the lead in building a new power system and new energy supply and consumption system in Ningxia, serving the high-level construction of a national new energy comprehensive demonstration zone in the autonomous region.
