Construction began on October 21 for a 7-MW/42-MWh vanadium-flow battery demonstration project at China Mobile’s Huainan data center.

A report citing Wenergy Group’s public account says the project held its groundbreaking ceremony on October 21. The ceremony marked its formal entry into construction implementation, rather than commissioning or commercial operation.

The installation is an all-vanadium flow-battery energy-storage demonstration project associated with China Mobile’s Yangtze River Delta data center in Huainan. The report identifies Juhe Energy as the project company and places the site in Huainan’s High-Tech Development Zone.

The specified 7 megawatts (MW) describe the battery system’s power rating, while 42 megawatt-hours (MWh) describe its energy-storage capacity. These figures are not the data center’s computing capacity or total electrical load; the supplied source gives no project cost or completion date.
