102MW/228MWh hybrid system (LFP + vanadium flow) strengthens winter peak support, boosts grid flexibility, and accelerates low-carbon transition
On 1 January 2026, Wujing Power Plant announced that Shanghai’s first power-side independent energy storage station has officially entered commercial operation. Designated as a flagship demonstration project under Shanghai’s “15th Five-Year Plan” for new-type energy storage, the facility will provide critical flexible regulation capacity—strengthening grid stability and helping secure reliable electricity supply during the winter peak season and in the years ahead.
The newly commissioned facility delivers 102MW / 228MWh of storage capacity and was built through an innovative “asset revitalization” approach. By repurposing existing on-site coal yard land and independently refurbishing and reusing bays of a long-idled 220kV step-up substation, the project achieved a highly intensive construction model with no additional land acquisition and no new external transmission lines.
To strengthen long-term operational performance, Wujing Power Plant implemented dedicated technical training and involved its electrical maintenance and operations personnel throughout equipment installation and system commissioning. Ahead of commercial operation, the plant established a professional team capable of independently operating and maintaining an independent energy storage station—reducing lifecycle operating costs while creating new career development pathways for employees.
The station adopts a hybrid storage architecture combining lithium iron phosphate (LFP) batteries and vanadium flow batteries, supported by layered fire protection measures and physical isolation systems designed to enhance overall safety. Once in service, the facility can function as a fast-response “super power bank,” rapidly following grid dispatch instructions to improve peak-shaving capability and strengthen supply reliability across key areas of Shanghai.
Environmental and economic benefits are also expected to be significant. Project estimates indicate that, after commercial operation, the station could support higher renewable energy integration and reduce carbon dioxide emissions by approximately 19,000 tonnes per year over the next three years.
