30 Second Briefing
XCMG all‑electric heavy‑duty trucks have completed trial runs on the 700 km haul route between Codelco’s Chuquicamata copper mine and the port of Mejillones in northern Chile with zero reported malfunctions. The route, crossing the western Andean foothills, tests traction, braking and battery performance under high-altitude gradients, long downhill sections and desert temperatures. Successful operation over this distance signals growing feasibility of battery-electric haulage for mine‑to‑port logistics, with implications for charging infrastructure design, duty‑cycle planning and fleet energy management.
Technical Brief
- Trial used XCMG all‑electric heavy‑duty road trucks on a long-distance mine–port logistics corridor.
- Alignment straddles western Andean foothills, implying repeated long gradients and altitude‑related power derating checks.
- Desert environment adds thermal loading on traction batteries and power electronics during extended continuous operation.
- For other long mine–port corridors, such trials inform transition thresholds between diesel, hybrid and fully electric haulage.
Our Take
Codelco’s earlier 680 km electric haul trial with SANY between Radomiro Tomic and Angamos Port suggests the Chuquicamata–Mejillones 700 km route is part of a systematic programme to electrify long-distance copper logistics in northern Chile, rather than a one-off demonstration.
With Chile aiming to fast-track over $100 billion in mining investment, sustained trials of XCMG electric trucks on a key export corridor from the Chuquicamata copper mine position Codelco to meet tightening decarbonisation expectations without waiting for rail or port-side infrastructure overhauls.
Our database shows multiple recent Codelco items tied to operational reliability at Chuquicamata (including major conveyor belt upgrades), and layering electric road haulage onto this asset base signals that decarbonisation is now being integrated into core production and transport systems rather than treated as a peripheral pilot.
