Do Fortescue’s plans to eliminate gas and diesel stack up?

Friday 15 May 2026

Mining giant Fortescue’s ambitious plan to completely eliminate fossil fuels from its Pilbara iron ore operations has faced skepticism, but a new financial analysis reveals the transition makes massive economic sense - driven almost entirely by the shift to battery-electric haul trucks.

While investing in large-scale solar and wind farms to replace gas power offers relatively low financial returns on its own, the real jackpot lies in the pits. Replacing a traditional diesel haul truck with an electric equivalent slashes annual operating and fuel costs from A$2 million down to just A$590,000 - saving a staggering A$1.4 million per truck every single year.

Scaled across Fortescue’s 360-truck fleet, these efficiencies translate to roughly A$500 million in annual savings. Even when accounting for the premium cost of electric vehicles and heavy charging infrastructure, the fleet investment achieves a payback period of less than three years, proving deep industrial decarbonisation can be highly profitable.
