At 18:18 on 28 August, the first phase of the State Power Investment Corporation (SPIC) Sichuan Panzhihua 100MW/500MWh Vanadium Flow Battery Energy Storage Power Station was successfully connected to the grid following completion of technical commissioning. This achievement marks a significant milestone for Panzhihua in advancing new energy storage technologies and establishes Sichuan’s first grid-connected vanadium flow energy storage project.
Located in the National Vanadium & Titanium High-Tech Industrial Park, the project features 48 large battery containers utilizing internationally advanced vanadium flow battery technology. With a storage capacity of 500,000 kWh, the facility can discharge continuously for 5 hours – equivalent to the annual electricity consumption of 200 households – and enables local consumption of renewable power within the industrial park.
“This project demonstrates deep integration between central enterprise technology and local industrial chains. It will greatly strengthen Panzhihua’s vanadium industry ecosystem, from vanadium resources and electrolyte production to battery stacks and system integration, supporting the development of a world-class vanadium and titanium industrial cluster,” said Yang Yuchi, Deputy Director of the Administrative Committee of the National Vanadium & Titanium High-Tech Industrial Park.
Construction of the project took just nine months from initiation to operation, filling a gap in large-scale long-duration energy storage applications in Panzhihua. The facility can complete approximately 85,000 kWh of charging and 60,000 kWh of discharging per day, significantly enhancing renewable energy consumption capacity.
Core advantages of the vanadium flow battery station include:
- High safety, long cycle life, and stable storage capacity
- Super “power bank” functionality, storing surplus green electricity and releasing it during peak demand with millisecond-level response
- Large-scale grid stability, with 60MWh regulation capability that smooths renewable generation fluctuations and supports smart coordination with the main grid
According to Shao Wang, Director of the Development Department at SPIC Sichuan Wind Power Company, planning is already underway for Phase II, which will combine vanadium flow energy storage with hydrogen-fired generation.
Invested and built by SPIC Sichuan Electric Power Co., Ltd., the project is expected to raise renewable energy utilization in the region by 6.64 percentage points annually, equivalent to an additional 21.25 million kWh of green power consumption and a reduction of approximately 1.353 million tonnes of carbon emissions each year.
This project not only marks Sichuan’s entry into large-scale vanadium flow energy storage but also provides critical support for China’s “dual carbon” strategy and the construction of a new-type power system.
