BHP Group Limited deployed two Caterpillar 793 XE Early Learner battery‑electric haul trucks to its Jimblebar iron‑ore mine on December 5 2025, marking the first use of electric haulage in the Pilbara region. The trucks are part of a joint trial with Rio Tinto and Caterpillar that will evaluate battery performance, charging infrastructure and operational integration in the region’s harsh, high‑temperature environment.
The Early Learner designation signals that the trucks are in a testing phase rather than a commercial rollout. The trial will assess how the vehicles perform under continuous, high‑load conditions, how quickly they can be recharged, and how they fit into existing mine workflows. Successful results could enable BHP to replace diesel‑powered haul trucks, reduce fuel costs, and cut operational emissions—key levers in the company’s net‑zero 2050 target.
Tim Day, BHP’s Western Australia Iron Ore Asset President, said powering up the first battery‑electric haul trucks is an important step toward decarbonisation. Andrew Wilson of Rio Tinto noted that decarbonising a fleet of 18 Pilbara mines is a significant challenge, and Marc Cameron of Caterpillar highlighted that industry‑wide collaboration is essential to accelerate innovation and bring sustainable solutions to market.
The trial aligns with BHP’s broader electrification strategy, which includes solar and battery storage projects across the Pilbara. By partnering with Rio Tinto and Caterpillar, BHP shares the risk and cost of developing charging infrastructure and training staff, while positioning itself as a leader in mining electrification. Headwinds include the upfront capital for charging stations, battery longevity in extreme conditions, and the need for workforce up‑skilling, but the potential tailwinds—regulatory pressure, investor focus on ESG, and long‑term fuel savings—support the initiative’s strategic value.
While no immediate market reaction data is available, the deployment signals to investors and regulators that BHP is actively pursuing technology that can materially reduce its operational emissions and operating costs. The move may influence BHP’s competitive positioning in a sector increasingly judged on sustainability performance.
BHP’s deployment of the Early Learner trucks represents a milestone in the company’s decarbonisation journey. If the trial demonstrates reliable performance and cost advantages, BHP could scale battery‑electric haulage across its Pilbara fleet, delivering measurable emissions reductions and fuel‑cost savings that reinforce its net‑zero commitments and strengthen its leadership in mining electrification.
