In recent years, the installed capacity of vanadium flow batteries has continued to grow rapidly. Data shows that in 2024, a total of 23 related projects were tendered nationwide, with a total scale of 849.85 MW/3,712 MWh. The average winning bid price was RMB 2.1/Wh, a year-on-year decrease of 20%. A total of 18 projects were delivered, with a total scale of 612 MW/2,438 MWh. Among them, Rongke Power delivered 1,428 MWh, accounting for nearly 60% of the total. The total delivery volume of vanadium flow batteries in 2024 increased by 600% compared to the previous year.
Introduction to Rongke Power
As of now, Rongke Power has built and is constructing projects with a total scale of 3.9 GWh. Its industrial base planning is clear and divided into three core sections:
The first section is the material base, with a core focus on the specialized production of high-performance vanadium and vanadium electrolyte. The second section is the vanadium battery energy storage equipment manufacturing and system integration base, focusing on core equipment production and overall system solution delivery.
The third section is the flow battery and hydrogen energy innovation incubation base. Given the significant commonalities in technical principles, R&D, and application between vanadium electrolyte hydrogen production technology and vanadium battery core materials, hydrogen energy has been clearly identified as one of Rongke’s long-term strategic development directions.
Rongke Power’s main business includes the supply of vanadium flow battery energy storage equipment, power station solutions, operation and maintenance services, and it owns a CNAS-certified energy storage battery testing center.
Its product system includes the early indoor application VPower series—500 kW/750 kW, with a DC-side efficiency of over 80% and an operating temperature of 5–35°C; the current mainstream outdoor TPower series—500 kW/750 kW, configurable for 4/5/6-hour capacity, with a DC-side efficiency of over 80%; as well as small customized products such as UPower and SPower, used in scenarios like urban lighting.
Typical projects demonstrate Rongke Power’s technical reliability and market competitiveness. The 2012 5 MW/10 MWh project at Guodian Longyuan Wind Farm in Faku, Liaoning, has been operating stably for 13 years with a capacity retention rate of 100%. The Dalian Flow Battery Energy Storage Peak-Shaving Power Station, a national demonstration project, collaborated with Huaneng and State Grid in 2024 to complete the world’s first large-capacity thermal power unit black start of an urban power grid using new energy storage.
The Xinjiang Aksu 175 MW/700 MWh project (70% undertaken by Rongke) is the first large-scale grid-side vanadium flow battery energy storage project in China. The Three Gorges Energy Jimusaer 200 MW/1,000 MWh project, independently undertaken by Rongke, marks the entry of vanadium flow batteries into the GWh era.
The Jilin Songyuan project, as the first centralized shared energy storage power station in Northeast China, adopts an innovative leasing and dispatch model. The 6 MW/36 MWh project in collaboration with Conch Cement adopted an electrolyte leasing model, achieving an AC-side efficiency of 65%. The Saudi Aramco 90 kW/1,000 kWh project is the world’s first long-duration energy storage application (exceeding 11 hours) in an oil and gas field scenario.
In the field of vanadium flow battery cost control, Rongke Power has established a multi-dimensional cost reduction path of “technological innovation + scaled procurement + financial innovation” to systematically advance the achievement of cost reduction goals.
