The deal was signed with EMOAC, which has worked as COPEC’s energy trader since 2020, and will last for 15 years, but Atlas did not announce when it expects to begin commercial operation of the BESS. The company has already contracted 5.2GW of renewable capacity in Latin America, and the deal follows a number of other investments into the region, including the signing of a PPA with mining company Codelco for “24/7 renewable energy” earlier this month.

“The BESS del Desierto project is a key part of our strategy to enhance energy reliability in the region through advanced solar resource utilisation and offer customised energy solutions to our clients,” said Carlos Barrera, CEO of Atlas Renewable Energy.

This latest development in the Chilean storage sector follows Engie’s launch of commercial operations at a 139MW/638MWh BESS earlier this month, also in Antofagasta. Spanish firm Ingeteam has also announced a collaboration with Grenergy on the Oasis de Atacama project, a solar-plus-storage project that is expected to have a storage capacity of 4.1GWh, the largest of any facility in the world.

These investments come as Chile looks to significantly expand both its renewables and storage sectors, with the government aiming to meet 70% of its energy demand from renewables by the end of the decade. Research firm Interact Analytics forecasts Chile to add more than 1GW of new storage capacity to the national grid each year between 2024 and 2026 to minimise the variability of these renewable power investments.
