A joint venture between Chilean and French partners has submitted a US$900 million pumped-storage hydropower project for environmental review in Chile's Atacama Region.
The Central de Bombeo Atacama plant, located in Caldera, marks a significant step in the development of energy infrastructure in one of the country's most arid and resource-rich areas.
The filing signals growing investment in grid stability solutions as Chile seeks to balance its expanding renewable energy portfolio with storage capacity.
Pumped-storage facilities are critical for managing intermittency in wind and solar generation, which are increasingly dominant in the national mix.
This development arrives amid heightened environmental scrutiny for industrial projects in the region.
Major miners, including BHP, have recently faced rigorous approval processes for operations in Atacama, with BHP recently submitting an application to reopen its Cerro Colorado copper mine contingent on adopting recycled water systems.
