    Aggreko–Harmony Eva copper hybrid plant: power and pit planning notes for engineers

    April 2, 2026|

    Reviewed by Joe Ashwell

    First reported on International Mining – News

    30 Second Briefing

    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.

    Technical Brief

    • Contract term is explicitly “minimum 15 years”, allowing long‑horizon mine planning around a fixed power solution.
    • Facility is described as Australia’s largest off‑grid renewable hybrid plant, indicating multi‑tens of megawatts scale.
    • Hybrid configuration integrates on‑site renewables, thermal generation and battery energy storage for grid‑quality power in islanded mode.
    • Remote northwest Queensland location necessitates full electrical islanding, with no reliance on the National Electricity Market.

    Our Take

    In our database, Harmony’s Eva copper project in Queensland appears repeatedly alongside major contracts to Thiess and Metso, signalling that the Aggreko offtake-style power deal is part of a coordinated build-out of mine, plant and energy infrastructure rather than a standalone sustainability gesture.

    Aggreko’s recent commentary on fuel price volatility in African mining, also in our coverage, underlines that the Eva copper power purchase agreement in Australia fits a broader commercial push by the company to replace diesel-exposed generation with hybrid systems at remote copper and gold operations.

    Battery and electric vehicles in mining: design and power notes for engineers

    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.

    Metso Robotic Split Strip: cathode stripping design notes for copper plant engineers

    Metso has launched the Outotec Robotic Split Strip, a compact hydraulic‑robotic system for separating copper cathode sheets from mother plates in electrorefining circuits, designed for both greenfield and brownfield plants. The unit uses robotic handling and flexible tooling to improve stripping precision and reduce sheet damage and copper waste compared with conventional mechanical strippers. For plant engineers, the modular layout and automation focus allow retrofit into existing cells with minimal footprint, supporting tighter process control and more consistent cathode quality.

    Northern Star March gold surge: ramp-up implications for mine planners and contractors

    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.
