State Grid Huai'an Powers Up City's Largest User-Side Energy Storage Station

On December 28, 2024, State Grid Huai'an Power Supply Company successfully connected and put into operation the city's largest user-side energy storage station, with an installed capacity of 60 MW/120 MWh. This will significantly enhance the peak-shaving capability of the Huai'an power grid during the winter.

User-side energy storage mainly takes advantage of the price difference between peak and valley electricity rates to reduce enterprise costs, while also optimizing power supply quality, improving the local consumption rate of renewable energy, and reducing the peak-valley difference of the grid. The project adopts a fully self-use model and is expected to reduce the grid's supply load by 60,000 kW during peak load periods, providing strong support for winter power security in the Huai'an area.

The main investor of this energy storage project is a key enterprise in Huai'an, which has an annual electricity consumption of over 1 billion kWh. State Grid Huai'an Power Supply Company actively practices the “Electric Warm Current” brand initiative of State Grid Jiangsu Electric Power, which focuses on multiple measures to ensure power supply. The company supported users by conducting potential analysis for energy storage construction, precisely planning the project scale, and organizing multi-disciplinary expert groups to form a service team. The project was completed and put into operation in less than three months.

In addition, State Grid Huai'an Power Supply Company has also formed a specialized technical team called "Huai Shang Xin" to provide users with training on virtual power plants and auxiliary services. This is expected to save over 30 million yuan in electricity costs annually.

In recent years, the Huai'an area has actively improved its "green content" to enhance its development "golden content." Data shows that there are currently 17 user-side energy storage systems in operation in Huai'an, with a total scale of 90.56 MW/218.88 MWh. It is expected that by the end of 2025, the city's user-side energy storage capacity will exceed 200 MW/400 MWh.
