Chile Valparaiso energy storage lithium battery manufacturer

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.

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.

In March 2024, BESS Coya, the largest battery-based energy storage system in Latin America, started operations. The facility is located in the Antofagasta region and has a storage capacity of 638 MWh, with 139 MW of installed capacity. The project utilizes lithium-ion batteries and stores the energy generated by the 180-MW Coya photovoltaic plant.

In fact, batteries charged at nearly $0/MWh during the day in the sunny, northern desert regions of Chile, sell energy at night for over $100/MWh. Although projects such as Engie's BESS Coya are already enjoying these large spreads, this capacity payment will partially de-risk Chile's dependence on volatile, but still profitable, merchant revenues.

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.

According to a December 2023 publication on the InvestChile website, the country had 23 approved energy storage projects with a total of 3,000 MW of capacity. Chile is exploring a variety of solutions to keep abreast of the changing energy demand landscape ranging from BESS to innovative projects using CO2.
