BHP and Rio Tinto megawatt Cat 793 XE charge: haulage design notes for engineers
Reviewed by Joe Ashwell
First reported on International Mining – News
30 Second Briefing
BHP and Rio Tinto have completed what they describe as the first “megawatt scale” (>1 MW) fast charge of a Cat 793 XE Early Learner battery-electric haul truck at BHP’s Jimblebar iron ore mine in Western Australia’s Pilbara. The ultra-class truck is one of two 793 XE units under joint evaluation, aimed at validating high‑power charging, duty cycles and electrical infrastructure integration in a production-scale pit environment. Successful megawatt charging is a key step towards fully electrified 220–250 t class haulage fleets on long Pilbara ramps.
Technical Brief
- Megawatt-scale charge was delivered into a Cat 793 XE Early Learner truck at Jimblebar.
Our Take
BHP’s work on megawatt‑scale charging at the Jimblebar iron ore mine sits alongside its broader technology push highlighted in our recent piece on Edgar Basto’s performance agenda, signalling that haulage electrification is being treated as a core productivity lever rather than a standalone sustainability trial.
Within our 67 keyword‑matched iron ore items, Pilbara operations like Jimblebar are among the few experimenting at this power level for haul truck charging, which is likely to influence future tender specs and grid‑connection designs for new Western Australia iron ore expansions.
For Rio Tinto, which features heavily in our critical minerals and Argentina coverage, collaborating on 1 MW‑class charging in the Pilbara suggests it is road‑testing infrastructure and operating models that could later be adapted to lower‑emission haulage at its copper and battery‑metal projects elsewhere.
