Huawei and SchneiTec Launch First TÜV SÜD-Certified Grid-Forming Energy Storage Project in Cambodia

SHANGHAI, June 16, 2025 /PRNewswire/ — Huawei Digital Power, in partnership with SchneiTec, has successfully commissioned Cambodia’s first TÜV SÜD-certified grid-forming energy storage project. This achievement marks a significant milestone in the country’s transition to a sustainable energy future. SchneiTec, a prominent energy solutions provider in the region, previously developed Cambodia’s largest solar power plant.

The newly completed energy storage project features a capacity of 12MWh, which includes a 2MWh testbed specifically designed to validate Huawei’s Smart String Grid-Forming ESS technology. This system has proven its exceptional capabilities in stabilizing the grid in both off-grid and weak-grid scenarios, facilitating the seamless integration of intermittent renewable energy sources.

This project has received official certification from TÜV SÜD, marking Cambodia’s inaugural deployment of a grid-forming ESS and establishing a solid foundation for future capacity expansion and large-scale energy infrastructure development. The project underwent joint testing by TÜV SÜD, SchneiTec, and Huawei Digital Power. TÜV SÜD, known globally for its stringent standards in energy technology testing and certification, verified critical technical capabilities of Huawei’s Smart String Grid-Forming ESS, including inertia response, high/low voltage ride-through, frequency support, and overload performance.

### Key Testing Highlights:
This independent verification of Huawei’s grid-forming ESS technology represents the first overseas on-site validation of the system, fully compliant with international standards, including IEC, China National Standards, the UK Grid Code, and Germany’s VDE standards. The TÜV SÜD certification confirms that Huawei’s grid-forming ESS technology meets globally recognized benchmarks for energy management and grid stability.

This milestone signifies a major achievement in Huawei Digital Power’s technological development and represents a landmark moment in the evolution of innovation within the energy sector. The collaboration between Huawei Digital Power and SchneiTec marks a significant advancement in Cambodia’s renewable energy transition. As the country continues to progress on its renewable energy roadmap, Huawei Digital Power is committed to driving innovation, delivering stable, scalable, and reliable solutions to meet the growing demand for sustainable electricity, and supporting the development of its energy infrastructure.
