Electrification of mining fleets is advancing beyond early pilots, with battery-electric haul trucks, loaders and light vehicles moving from trial phases into multi-year deployment contracts despite recent pull-backs in some OEM roadmaps. Dan Gleeson details how mines are pairing 6–8 MWh battery trucks with on-site fast-charging bays and trolley-assist lines, and integrating underground BEVs with upgraded 11 kV substations and ventilation recalculations. Operators are reassessing mine plans, ramp gradients and power quality to manage peak loads, charger placement and heat rejection from high-capacity battery systems.

Aggreko has signed a minimum 15‑year power purchase agreement with Harmony Gold to build and operate what is described as Australia’s largest off‑grid renewable hybrid power facility for the Eva copper project in northwest Queensland. The build‑own‑operate arrangement will combine on‑site renewables with thermal generation and battery storage to supply continuous power to the remote open‑pit operation. For mine planners and process engineers, the long‑term PPA locks in a dedicated low‑emission power source, influencing pit expansion options, processing throughput and future electrification of mobile fleets.

Northern Star Resources’ March quarter gold sales have surged, signalling a production ramp-up across its Western Australian assets including Kalgoorlie Consolidated Gold Mines and the Super Pit. Management is positioning for record output in FY25–26 as processing throughput and mine development advance at key hubs such as Yandal and Pogo, supported by higher mill utilisation and improved grade control. For contractors and suppliers, the trajectory points to increased demand for underground development, open-pit fleet capacity, and plant optimisation services over the next 12–18 months.
