Recently, construction of China’s largest user-side energy storage project - the 107.12 MW / 428.48 MWh Guangyuan Zhongfu & Guangyuan Linfeng User-Side Lithium Battery Energy Storage Project in Sichuan Province - has entered its final phase. Since construction began on July 30, 2025, all work has proceeded steadily according to plan, with full efforts now focused on achieving the completion target of November 30.

The project is jointly developed by Great Power, a leading company in the energy storage industry, and Henan Zhongfu High Precision Aluminum Co., Ltd (Zhongfu Aluminum), a top enterprise in the aluminum sector. Located only 210 meters from Zhongfu Aluminum’s plant, the project directly connects to the 10 kV power distribution system, significantly reducing transmission losses and improving energy efficiency. It is linked via cables to two 220 kV substations in the industrial park and operates on a “charging during off-peak, discharging during peak” model, with a maximum charge/discharge power of 107 MW and a total capacity of 428.48 MWh, allowing for 4 hours of full charge and discharge per cycle.

Once operational, the project will not only reduce electricity costs and enhance power reliability for Zhongfu Aluminum, but also help the power grid with peak shaving and load balancing. According to plans, Phase II of the project construction will expand the system to 400 MW / 1,000 MWh, along with the construction of a new 220 kV substation, wind and solar power facilities, and EV charging stations. Ultimately, the project aims to establish an integrated “generation - grid - load - storage - charging” regional microgrid in Guangyuan, Sichuan province, providing a practical model for China’s power market reform and carbon neutrality goals, while injecting green momentum into the city’s economic and social development.
