The Chilean Environmental Impact Assessment System (SEIA) has approved the 250 MW “Battery Energy Storage System – BESS La Isla” project in Llay Llay, Valparaíso, which will use lithium ferrophosphate (LFP) battery technology with a total capacity of 1,250 MWh. The $300 million La Isla project will be located in the Valparaíso region. The project aims to integrate with. With 23 energy storage projects already approved, totaling an impressive 3,000 MW of capacity, Chile is at the forefront of innovation and efficiency in Latin America. During its recent participation in COP28 in Dubai, Chile not only reaffirmed its commitment to renewable energy, but also. Santiago, Chile / Milan, Italy – December 1, 2025 – Limes Renewable Energy (Limes), a global developer specialising in solar, wind and battery energy storage system (BESS) projects, has successfully secured the Environmental Qualification Resolution (RCA) for its Pradera Larga project in Chile's. This momentum is reflected in the data: AMI estimates that there is a 7.

Currently, 36 of the 129 large-scale projects Latin America projects with an energy storage component under development are in Chile, including 32 out of 71 of the region's early works projects. The storage technologies either in use or being considered include:
While many projects are under development, lithium - ion battery storage is still limited. According to data from Acera, the Chilean Renewable Energy Association, there are only 64MW of battery storage capacity currently active, representing 0.2% of national capacity.
Are battery energy storage systems a viable alternative for Chilean power producers?
With transmission lines at overcapacity and permitting delays slowing the development of new grid infrastructure, battery energy storage systems (BESS) have surged as a profitable alternative for Chilean power producers.
According to data from Acera, the Chilean Renewable Energy Association, there are only 64MW of battery storage capacity currently active, representing 0.2% of national capacity. AES Andes, a subsidiary of U.S. company AES Corp. operates all 64MW at their Angamos and Los Andes substations.
