Chile’s Atacama energy storage build‑out: power contract insights for miners
Reviewed by Tom Sullivan

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.
