Mozambican graphite mine adopts hybrid energy solutions

Syrah Resources’ Balama graphite mine in Mozambique has approved a solar and battery renewable energy solution at its operation, thereby de-risking its energy supply while reducing operational costs and carbon emissions.  

The move by Syrah Resources is indicative of an ongoing shift within the African mining sector, whereby mining companies are actively seeking ways to improve their self-reliance, operational costs, and the overall sustainability of their operations. The proposed 11.25 megawatt peak (MWp) solar photovoltaic (PV) AND 8.5 megawatt hour (MWh) battery energy storage system (BESS) at the Balama mine will reduce diesel consumption for power generation by 35%. The solar PV system will have the capacity to supply up to 100% of the mine’s power requirements during peak daylight hours. The BESS system will alleviate the reliance on the current diesel plant, reducing operational and long-term sustaining costs. The renewable energy system is forecasted to save approximately US$8/t at a 15,000tpm production rate.

The PV system and BESS plant will be delivered and financed by CrossBoundary Energy in partnership with SolarCentury Africa which has the development lead role. The integrated, renewable energy solution is expected to be commissioned and operating before the end of March 2023. African mines are proving to be pioneers in hybrid energy adoption, being spurred on by increased oil prices and the lack of energy access at remote sites.
