China Accelerates Construction of 300MW/1200MWh Vanadium Flow Battery Project in Yunnan

Massive VRFB Project Accelerates in Yunnan

The 300MW/1200MWh vanadium redox flow battery (VRFB) energy storage project in Yongren County, Chuxiong Prefecture, Yunnan Province, is rapidly advancing. As the largest under-construction VRFB project in China, it boasts a total investment of 3.382 billion RMB and a 25-year operational lifespan.

Currently, electrolyte filling has reached 48.54%. Project managers expect to complete all filling and joint debugging by the end of October, with grid connection targeted for the end of the year. Once operational, the station is projected to charge over 720 million kWh and discharge over 504 million kWh annually.

Building a Comprehensive Supply Chain Ecosystem

Chuxiong Prefecture is leveraging this flagship project to construct a full VRFB industry chain. Led by Jinjiang Energy Group, the region is strategically allocating resources. Yongren focuses on stack manufacturing and system integration, featuring a 500MW/2GWh integration production line operating at full capacity to supply the local storage station.

Meanwhile, Lufeng County is developing upstream materials, including a 5,000-cubic-meter vanadium electrolyte production line, and Yuanmou is building an equipment base. By attracting industry leaders like Shanghai Electric and Zhejiang Juhuang Energy Storage, Chuxiong has formed a closed-loop industrial ecosystem, currently ranking first in Yunnan for installed storage capacity.

Expanding Regional Storage Capacity

Expanding beyond Yongren, Shuangbai County has initiated a 200MW/800MWh grid-forming intelligent VRFB project. This initiative will combine with projects in Yongren and Lufeng to create a diverse regulation system featuring both long-duration and short-term adjustment capabilities. Furthermore, the grid connection engineering for the South Grid Lijiang Huaping Industrial Park VRFB shared energy storage station has been successfully completed, laying a solid foundation for its timely production.
