The Lufeng City 100MW/400MWh vanadium flow battery (VFB) shared energy storage project has officially been commissioned, marking a major step forward for Yunnan Province and Chuxiong Prefecture in advancing long-duration energy storage and integrated renewable development. Invested in by Chuxiong Jinneng New Energy Co., Ltd., the project adopts a vanadium flow battery energy storage system with independent intellectual property and is described as Yunnan’s first grid-side shared energy storage station using the vanadium flow battery technology route.
At the commissioning ceremony, local leaders and project partners highlighted the project’s role in supporting China’s “dual-carbon” goals and strengthening regional clean-energy infrastructure. Lufeng City officials noted the project’s rapid delivery—from groundbreaking to commissioning in 232 days—as an example of “Lufeng/Chuxiong speed” enabled by coordinated efforts across government, finance, design, engineering, and technology partners.
Project Overview
- Capacity: 100MW / 400MWh vanadium flow battery energy storage system
- Project type/positioning: Grid-side shared energy storage
- Site area: 53.09 mu (approx. 3.54 hectares)
- Grid connection infrastructure: New 220kV step-up substation and dual-circuit 8.7 km 220kV line, connected via a “π” connection to the Yishan Wind Power project and the 500kV Heping substation line
- Total investment: RMB 1.237 billion
- Design operating period: 25 years
Expected Economic and Grid Benefits
Upon full operation, the station is expected to deliver:
- Annual charging energy: ~240 million kWh
- Annual discharge energy: ~168 million kWh
- Annual output value: ~RMB 108 million
- Annual tax contribution: ~RMB 13 million
The project is also expected to support employment and local income growth, while providing critical flexibility for large-scale wind and solar integration in central Yunnan—helping to ease grid consumption pressure and reduce wind/solar curtailment by enabling deeper coordination between renewables, the grid, and energy storage.
The project was developed with participation from multiple organizations, including Chuxiong Jinneng New Energy Co., Ltd., China Construction Third Engineering Bureau, Sichuan V Liquid Energy Co., Ltd., and PowerChina Jiangxi Electric Power Design Institute.
