New 1 GWh production line in Anhui highlights accelerating industrialisation of vanadium flow battery manufacturing
A major new expansion in China’s vanadium flow battery (VFB) manufacturing sector is underway following the formal environmental acceptance announcement for a 1 GWh annual vanadium flow battery production expansion project by Shanghai Electric (Anhui) Energy Storage Technology Co., Ltd. in Chaohu Economic Development Zone, Anhui Province.
Publicly disclosed by the Anhui Chaohu Economic Development Zone Management Committee on 20 April, the project provides further evidence that China’s leading industrial groups are moving rapidly beyond pilot deployment and into large-scale standardised manufacturing of long-duration energy storage systems.
With the completion of the new facilities, Shanghai Electric’s Anhui production base will increase from its existing 1 GWh annual vanadium flow battery manufacturing capability to a total of 2 GWh, reinforcing the continued rise of domestic investment in non-lithium long-duration storage technologies.
Rising Demand Drives New Industrial Capacity
Shanghai Electric originally commissioned its first 200 MW / 1 GWh vanadium flow battery production line in Chaohu in 2020, with environmental completion and discharge approvals finalised during 2021. According to the latest official filing, the company notes that existing production capacity is no longer sufficient to meet growing market demand, prompting the need for further expansion.
The new project will include:
- Factory Building No.1 (5,511 m²) dedicated primarily to electrochemical stack manufacturing,
- Factory Building No.2 (5,511 m²) dedicated primarily to system integration,
- additional auxiliary production facilities and supporting equipment.
Construction is scheduled over a compressed three-month implementation period, highlighting both the maturity of the company’s manufacturing platform and the urgency with which suppliers are responding to a rapidly developing domestic order pipeline.
Although the approved filing lists a direct investment of RMB 15 million for the plant modification works, the broader significance lies in what the expansion represents: vanadium flow battery manufacturing in China is increasingly entering a repeatable GWh-scale industrial replication phase among major state-backed engineering enterprises.
China’s VRFB Sector Moves from Demonstration to Industrialisation
Shanghai Electric is one of a growing number of major Chinese industrial participants positioning vanadium flow batteries as a strategic technology for utility-scale long-duration energy storage, particularly in applications requiring:
- high operational safety,
- long service life,
- unrestricted deep discharge capability,
- stable multi-hour storage economics,
- and minimal performance degradation over decades of cycling.
Unlike lithium-ion batteries, VFB systems store energy in external liquid electrolyte tanks, enabling independent scaling of power and energy capacity. This architecture is increasingly attractive for renewable integration, peak shaving, grid balancing and long-duration dispatchable storage, where lifecycle stability and fire safety are becoming more important procurement criteria.
The Anhui expansion also reflects a broader structural change now taking place across China’s vanadium battery industry. Manufacturers are no longer building isolated demonstration assembly lines, but are beginning to establish serialised GWh-class production platforms capable of supporting sustained national deployment.
As China enters a new phase of accelerated long-duration storage tendering under provincial energy storage mandates and renewable curtailment reduction programmes, manufacturing scale is becoming one of the sector’s most important competitive variables.
Shanghai Electric’s latest expansion therefore provides a further indication that China is rapidly building the industrial backbone required to support large-scale commercial deployment of vanadium flow battery systems over the coming decade.
