    Chile’s Atacama energy storage build‑out: power contract insights for miners

    Chile’s Atacama energy storage build‑out: power contract insights for miners

    First reported on MINING.com

    30 Second Briefing

    A nearly $500 million solar‑plus‑storage plant in Chile’s Atacama Desert, ContourGlobal’s Victor Jara hybrid facility in Tarapacá, has begun operating with a 200 MW battery system capable of 6.5 hours discharge, backed by a 15‑year night‑time PPA with Copec EMOAC. Chile already has 3,072 MW of BESS operating or under test and expects a further 5,400 MW online by December, largely in the desert grid‑bottleneck zone where daytime solar is routinely curtailed. For mining and other energy‑intensive users, this rapidly expanding long‑duration storage fleet is key to securing firm, low‑carbon power contracts.

    Technical Brief

    • ContourGlobal’s Victor Jara plant is described as Latin America’s longest-duration utility-scale battery installation.
    • System configuration is solar-plus-storage, explicitly designed to shift surplus daytime PV into night-time delivery.
    • Victor Jara is ContourGlobal’s second Chilean solar‑storage asset, following the Quillagua project in Antofagasta region.
    • Atlas Renewable Energy’s Estepa hybrid project secured $510 million financing, positioning it among Chile’s largest solar‑storage builds.
    • Developers cited Chile’s regulatory framework, strong renewables pipeline and rising electricity demand as key investment drivers.
    • ContourGlobal is scoping further storage and wind projects nearer Santiago and in central–southern Chile, targeting data centre baseload demand.

    Our Take

    Within our 1189 Mining stories, Chile appears frequently in copper- and lithium-linked power deals, and the Estepa project’s 200 MW / 6.5-hour profile signals that large miners like BHP in northern Chile can now realistically substitute a significant share of thermal power with firmed solar for round-the-clock operations.

    The roughly $500 million solar-and-storage build in the Atacama Desert places Atlas Renewable Energy in the same investment scale band as AES Andes SA and Engie Energía Chile SA assets in our database, suggesting that independent power producers are now competing head-on with incumbents for long-duration supply to copper and lithium districts.

    Because the Atacama region underpins global copper and lithium supply alongside emerging cobalt and rare earth prospects, high-duration storage like Estepa reduces curtailment risk for future projects and is likely to become a de facto requirement in power tenders for new mines in northern Chile by December and beyond.

    Weir’s early-stage water management push: design and risk lessons for mines

    Early-stage water management embedded in mine design, rather than retrofitted later, is being pushed by Marnus Koorts, Director of Capital and Process at Weir, as a core variable alongside throughput and grind size. Koorts argues that integrating water balances, tailings deposition plans and pump/sump layouts from concept study stage cuts risk of flooding, unplanned dewatering and costly rework. For engineers, this means specifying pipelines, thickeners and water-recovery circuits in initial flowsheets, not as bolt-ons once pit expansion or TSF instability exposes gaps.

    ICMM names Froydis Cameron-Johansson CEO: ESG and tailings impacts for miners

    ICMM has appointed Froydis Cameron-Johansson as its next President and CEO, effective 23 November 2026, succeeding Rohitesh Dhawan after more than five years in the role. Cameron-Johansson brings senior global leadership experience from major mining houses, positioning her to influence ICMM’s work on tailings governance, Scope 3 emissions and responsible sourcing standards across its 26 member companies. Leadership continuity at ICMM matters for operators because its frameworks often feed directly into site-level ESG criteria, investor due diligence, and permitting expectations.

    McKinsey’s 2026 gold-led mining returns: key asset optimisation lessons for engineers

    Record metals and mining returns entering 2026 are being driven largely by gold, with sector-wide market capitalisation at an all-time high and balance sheets among the strongest in a decade, McKinsey’s Global Materials Perspective 2026 reports. Behind the headline numbers, overall industry productivity has stalled and value creation is increasingly concentrated in a small group of top-quartile performers. For operators, this points to growing pressure to extract more value from existing assets through operational excellence, brownfield debottlenecking and disciplined capital allocation rather than volume-led growth.
