Project Overview
- ●LocationTongxin County, Ningxia
- ●Scale1 GW / 2 GWh
- ●ValueThe project delivers full-spectrum grid support – including fast frequency regulation, reactive power compensation, fault ride-through (FRT), and black-start capability. It effectively smooths output fluctuations from wind and solar generation, strengthens grid security and stability, and defers investment in transmission corridors and thermal peaking plants – reducing grid expansion costs. The system adopts a 587Ah cell + 6.25 MWh container + string PCS architecture, delivering high system efficiency, deep depth of discharge (DOD), and superior capacity retention. Revenue is generated through multiple channels – spot market price spreads, capacity payments, and frequency regulation ancillary services – supplemented by various subsidies, delivering solid unlevered returns. As a 10 GW-scale shared energy storage demonstration project in Ningxia, it operates with zero carbon emissions throughout its lifecycle, accelerating the deployment of an integrated
