    Aggreko–Harmony Gold hybrid power deal: PPA lessons for remote mine planners

    Aggreko–Harmony Gold hybrid power deal: PPA lessons for remote mine planners

    First reported on Australian Mining

    30 Second Briefing

    Aggreko has signed a long-term power purchase agreement with Harmony Gold to build and operate what is billed as Australia’s largest hybrid power facility for the Eva copper mine project in northwest Queensland. The off-grid system is expected to combine high-penetration solar PV with thermal generation and battery energy storage, replacing conventional diesel-heavy supply for the planned open-pit copper operation. For mine planners and owners, the deal signals growing bankability of large-scale hybrid PPAs to cut power costs and emissions on remote greenfield sites.

    Technical Brief

    • PPA structure transfers design, construction, ownership and operation of the power plant to Aggreko.
    • Contract tenure is described as long-term, providing revenue certainty for both the power provider and mine owner.
    • Aggreko will integrate solar PV, thermal units and battery storage under a single control and dispatch system.
    • System design targets high renewable penetration while maintaining N-1 reliability for critical mining loads.
    • Harmony Gold secures fixed or indexed power pricing, de-risking operating cost forecasts for the Eva project.
    • Project is timed to align power plant commissioning with pre-production and ramp-up phases of the open-pit operation.
    • Deal adds to a growing set of large-scale hybrid PPAs in Australian remote mining, improving bankability benchmarks.

    Our Take

    Harmony Gold’s Eva copper project in Queensland already has major mine development and equipment contracts in place with Thiess and Metso, so locking in a large hybrid power facility with Aggreko effectively rounds out the core delivery chain for a rapid construction-to-production ramp-up.

    Harmony’s planned US$1.6 billion spend at Eva, targeting 100,000 t/y copper when combined with CSA output, means power costs and reliability in Australia will materially influence its copper cost base across the region, giving this hybrid power deal strategic weight beyond a single site utility decision.

    Aggreko has been publicly arguing for miners to reduce exposure to volatile fuel prices, and securing Australia’s largest hybrid power facility for a copper–gold project provides a high-profile reference case that could strengthen its pitch to other Australian and African mine operators in our database.

    Orica’s Danafloat copper flotation move: integration and design notes for plant engineers

    Orica has moved into copper processing chemistry by acquiring FMC Corporation’s Danafloat™ range of high-performance flotation collectors, used for copper and other “future facing” commodities. The deal covers proprietary formulations designed to maximise sulphide ore recovery and improve concentrate grade while reducing reagent dosage and environmental impact. For concentrator operators, this adds a major explosives and blasting supplier into the flotation reagent supply chain, potentially enabling tighter integration between upstream fragmentation and downstream recovery optimisation.

    National Group backing mining excellence: project delivery lessons for engineers

    Queensland-based mining services provider National Group is sponsoring a community-focused award recognising resources companies that show strong engagement and deliver measurable change across the sector. The award targets operators and contractors working in Queensland’s coal, metals and quarrying projects, with assessment centred on local employment, training programmes and long-term community investment rather than short-term donations. For geotechnical and mining teams, this signals growing scrutiny of how project delivery, contractor selection and site rehabilitation strategies translate into tangible regional benefits.

    Smarter filtration solutions: dewatering and tailings design notes for plant engineers

    Smarter filtration solutions in wet mineral processing are focusing on high-pressure tower filter presses for slurry dewatering, such as Thejo’s vertical plate designs that deliver low-moisture filter cakes and high filtrate recovery. Suppliers are pairing these presses with automated cloth washing, cake discharge monitoring and optimised cycle control to stabilise throughput and reduce unplanned downtime. For plant designers, the shift is towards integrating filtration with upstream thickening and downstream dry stacking to cut fresh water intake and tailings storage volumes.
