Sichuan Chuantou Electric Power Sales (SCIC), a subsidiary of Sichuan Energy Development Group, has successfully commissioned and put into commercial operation a 0.25 MW / 2 MWh vanadium flow battery energy storage system at the Sichuan Investment Building in Chengdu.
Located in the core commercial district along Tianfu Avenue, the project is currently the largest vanadium flow battery installation serving a commercial complex in downtown Chengdu. By adopting a long-duration, high-safety vanadium flow battery technology route, the project fills a key gap in large-scale vanadium flow battery applications in dense urban business districts and provides a practical reference for user-side deployment of this storage technology.
Designed for peak shaving and valley filling, the system is expected to reduce peak-period electricity purchases by approximately 400,000 kWh per year, easing peak-load regulation pressure on the grid. In the event of grid faults or outages, the system can rapidly switch into emergency power mode, supplying continuous power for no less than five hours to key areas such as the building’s core office zones—over three times the emergency support typically provided by conventional diesel generators.
Once in full operation, the project is expected to replace around 200,000 kWh of thermal power generation annually, cutting more than 520 tonnes of carbon dioxide emissions each year. This will provide an important demonstration of how advanced energy storage can support Chengdu’s green energy transition and low-carbon urban development.
SCIC has actively responded to the Sichuan Province “14th Five-Year Plan” for New Energy Storage Development, focusing on the deep integration of user-side energy storage with commercial office buildings and industrial parks. The successful commissioning of the Sichuan Investment Building vanadium flow battery energy storage station marks a major step forward in the company’s new energy storage deployment.
The project also helps to leverage and coordinate vanadium and titanium resources, vanadium electrolyte production, and system integration capabilities within Sichuan Energy Development Group, further contributing to the Group’s high-quality development and its strategic positioning in the emerging energy storage industry.
