SANY unveils Africa's largest solar-storage-diesel microgrid

On December 29, SANY Silicon Energy announced the commissioning of the Zambia Ruida Mining Microgrid Power Project, a hybrid energy system integrating solar, storage, and diesel power. This project is reportedly Africa's largest single-unit microgrid designed specifically for mining operations.

The hybrid microgrid system includes a 13 MWp solar photovoltaic (PV) array, a 39 MWh battery energy storage system, and a diesel generator for backup power. The system is designed to ensure a stable and reliable electricity supply for mining activities while reducing reliance on diesel fuel and supporting operational efficiency. The solar and storage combination provides clean energy, while the diesel generator ensures continuity in the event of fluctuations in renewable energy generation.

The project progressed from the signing of the Power Purchase Agreement (PPA) to commissioning in four months. This timeline was achieved despite challenges such as Zambia's complex terrain, harsh climate conditions, and logistical constraints linked to the country’s infrastructure. The microgrid is now operational, providing mining operations with energy self-sufficiency and stability, which are critical for consistent industrial performance.

SANY Silicon Energy has stated its intention to utilize the expertise and operational insights gained from this project in future renewable energy developments. The company has indicated plans to expand its deployment of hybrid microgrid systems across Africa and other regions, applying the lessons learned from the Zambia Ruida project to similar energy projects.
