Mine electrification

Here, we explore the transition of the mining industry toward all-electric operations powered by renewable energy microgrids. The Podcast highlights how replacing diesel machinery with electric vehicles (EVs) can significantly enhance operational safety, reduce ventilation costs, and eliminate harmful emissions in underground environments. It emphasises the importance of digitalisation and automation in creating more efficient, data-rich extraction sites. While the shift requires substantial technological investment and a newly skilled workforce, it offers a pathway to sustainable resource production. Furthermore, the University of Adelaide’s research capabilities and mobile test platforms are presented as vital tools for addressing technical challenges such as power quality and grid reliability. Global case studies illustrate that moving to hybrid or 100% green energy is already a growing reality for major mining companies

This study is from a collaboration between IGO, Perenti, and ABB, the work highlights how replacing diesel vehicles with battery electric versions (BEVs) can advance decarbonisation goals while improving worker safety through reduced noise and emissions. The research details essential charging strategies, such as battery swapping for heavy machinery and opportunistic charging for lighter vehicles, to maintain operational productivity. Financial analysis reveals that an electric transition is economically viable, with costs only marginally higher than traditional methods—a gap expected to close as technology prices fall. While logistical challenges like equipment lead times were identified, the findings provide a strategic roadmap for modernising power infrastructure in the mining sector.
