Building a Comprehensive VRFB Industrial Chain

The Chuxiong Prefecture in Yunnan Province is executing a strategic and comprehensive expansion of its vanadium redox flow battery (VRFB) industrial ecosystem. To address the critical bottleneck of upstream core materials, Lufeng City within the prefecture is accelerating the construction of an annual production line capable of yielding 5,000 cubic meters of vanadium electrolyte. This initiative is designed to secure the foundational supply chain for the rapidly growing LDES sector.

System Integration and Regional Synergy

Beyond raw materials, Chuxiong is also focusing on downstream manufacturing. Yongren County is developing a supporting production line for 500MW/2GWh VRFB system integration. By strategically attracting industry leaders such as Shanghai Electric, Sichuan Weili De, and Zhejiang Juhe Energy Storage, the Jinjiang Energy Group is orchestrating a highly synergistic industrial layout. This regional strategy forms a cohesive supply chain characterized by Lufeng supplying electrolyte, Yongren leading system integration, and Yuanmou coordinating equipment manufacturing, thereby creating a robust and localized VRFB manufacturing hub.

Chuxiong's holistic approach to the VRFB value chain—from electrolyte synthesis to system integration—positions the region as a formidable powerhouse in China's long-duration energy storage manufacturing landscape.

Deploying Grid-Forming Storage Solutions

Parallel to its manufacturing ambitions, Chuxiong is advancing cutting-edge project deployments. Shuangbai County has officially launched the implementation of a 200MW/800MWh grid-forming smart VRFB energy storage station. Unlike traditional grid-following systems, grid-forming technology provides essential inertia and voltage support, significantly enhancing grid stability in areas with high renewable penetration. This project will operate in tandem with the Yongren mega-project to create a diversified regulation system that combines long-duration storage with short-term frequency regulation. Currently, Chuxiong's total energy storage installed capacity ranks first in Yunnan Province, reflecting its aggressive and successful push towards a modernized, resilient energy infrastructure.
