BHP battery truck static charging at Jimblebar: productivity lens for mine planners
Reviewed by Joe Ashwell

First reported on International Mining – News
30 Second Briefing
BHP is running battery-electric haul truck trials at the Jimblebar iron ore mine in the Pilbara using two Caterpillar 793 XE Early Learner units, in a joint programme with Caterpillar and Rio Tinto. The focus is on quantifying productivity impacts of static charging, including effects on haul cycle times, truck availability and fleet scheduling compared with diesel 793s. Outcomes will directly inform future pit design, charging bay layout and power infrastructure planning for large-scale BEV deployment on similar ultra-class truck fleets.
Technical Brief
- Trials use two Caterpillar 793 XE “Early Learner” battery-electric haul trucks at Jimblebar.
Our Take
The related 17 September item in our database notes BHP has already quantified about 1,000 fewer operating hours per battery truck per year under static charging, which at a high‑throughput iron ore hub like Jimblebar in the Pilbara likely forces a rethink of fleet size and standby capacity to keep tonnes moving.
Among recent iron ore coverage, BHP and Rio Tinto feature heavily in Pilbara decarbonisation trials, so Caterpillar’s 793 XE Early Learners at Jimblebar will be closely watched as a benchmark for how quickly large OEM battery haulage can be made productivity‑neutral against diesel in large open pits.
With over 1,200 mining stories and a strong cluster around ‘Projects’ and ‘Sustainability’, Jimblebar’s battery‑truck trial stands out as one of the few that explicitly weighs carbon gains against quantified productivity loss, giving other iron ore operators a rare data point for their own electrification trade‑off studies.
