Huawei’s new platform builds on field experience gained from the Red Sea project in Saudi Arabia, where the company deployed a 1.3GWh battery system. According to Steve Zheng, President of Smart ESS Business at Huawei Digital Power, the system achieves 93.1% round-trip efficiency by utilizing a high-voltage 1000V AC architecture powered by silicon carbide components. By applying an optimizer to each battery pack and a controller to every rack, the design mitigates electrochemical inconsistencies that typically degrade system performance over time.

Scaling grid-forming capabilities

The shift toward grid-forming technology is driven by the need to maintain essential functions like black-start capability and frequency regulation as fossil-fuel plants retire. Huawei has defined six core capabilities for its system, including power oscillation damping and virtual synchronous generator modes. Rather than focusing solely on the density of individual containers, the company emphasizes plant-level optimization. This approach allows a 1GWh installation to reduce delivery timelines by 30% and footprint requirements by 1 square meter per megawatt-hour compared to conventional market solutions.

Technical performance is further bolstered by a dual-stage architecture, which Huawei argues provides superior safety during grid disturbances such as low-voltage or high-voltage ride-through events. As transmission operators in regions like the UK, Australia, and Germany introduce stricter technical requirements for grid-forming resources, Huawei is positioning its array-centric design to serve as the new standard for large-scale utility storage.
