Major Milestone: Commissioning of China’s Largest Energy Storage Station

On December 5, 2025, a significant advancement was achieved in the field of renewable energy with the successful commissioning of the first phase of China’s largest electrochemical energy storage station. This facility, having a capacity of 300 MW/1200 MWh, is powered by SINEXCEL’s state-of-the-art 1725-kW Power Conversion System (PCS). This undertaking is not only a notable achievement for SINEXCEL but also a crucial development for the energy sector, enhancing grid stability and accelerating the transition to renewable energy sources.

Overview of the Energy Storage Facility

This energy storage installation is part of a dual-project site intended to reach a total capacity of 600 MW/2400 MWh. It features 240 battery containers and 60 integrated prefabricated cabins. When fully completed, the project will operate under an innovative integrated model that harmonizes wind, solar, thermal, storage, and transmission technologies. This configuration aims to maximize the utilization of renewable energy and improve overall system flexibility.

SINEXCEL, which provided 60 of the prefabricated cabins with a combined total of 180 units of their 1725-kW PCS, has developed a technology with a peak efficiency reaching up to 98.5%. The PCS employs advanced multi-string technology that not only enhances battery protection but also supports flexible configurations—allowing for 1, 2, 4, or 8 battery strings. This flexibility is crucial for adapting to various energy needs and optimizing operational performance.

Moreover, the system’s combined AC/DC output facilitates easier system management and future expansions. To ensure durability, systems are equipped with cabinets rated at IP54 for reliable outdoor performance.

The rapid response time of just 10 milliseconds for real-time grid balancing positions this PCS product as compliant with essential standards across major global markets, including North America, Europe, Australia, Japan, and China.
