SINEXCEL has completed the grid connection of a 107.12MW/428.48MWh battery energy storage system in Guangyuan, Sichuan Province, making it an iconic C&I BESS project in China. Developed for aluminium producer Zhongfu Industrial, the system is engineered to significantly reduce electricity costs through peak shaving for industrial-scale energy storage in the electrolytic aluminium sector.
Primary aluminium smelting is highly energy-intensive, consuming 13-15 MWh per tonne produced, with power accounting for up to 40% of total costs. Furthermore, sudden power outages can trigger catastrophic multi-million-yuan losses due to electrolyte freezing, demanding exceptionally reliable PCS.
This BESS tackles these challenges head-on. By storing low-cost electricity during off-peak hours and discharging it during peak tariff periods, the system saves Zhongfu Industrial an estimated 140 yuan per tonne of aluminium. This translates to annual savings exceeding 60 million yuan while cutting CO₂ emissions by roughly 52,000 tonnes per year.
At the heart of the project are 104 SINEXCEL 1725kW PCSunits, paired with 5MWh battery containers in an efficient DC-coupled architecture. Operating derated to maximize longevity, the PCS is engineered for demanding industrial conditions, featuring rapid response with millisecond-level reactions, high efficiency peaking at 98.5% and robust stability with IP54 protection rating.
The 1725kW PCS is fully certified to CE, VDE 4110/4120 and EN 50549 for European markets, with additional grid-compliance certifications for the United States, Australia, Japan and Thailand, cumulative shipments surpassing 1GW worldwide.
