ENGIE has commenced commercial operations for two battery energy storage system (BESS) projects in Chile. The projects include the Libélula and Los Loros BESS, adding a combined 251 MW of storage capacity to the National Electric System. With the addition of these projects, ENGIE’s operational BESS portfolio in Chile has reached 663 MW.
Furthermore, the Libélula project, located in the Metropolitan Region, includes a 203 MW/1,034 MWh five-hour duration BESS along with a 140 MW solar plant comprising 245,560 solar panels. The project represents a total investment of $320 million. The Los Loros project, located in the Atacama Region, features a 48 MW/275.23 MWh BESS comprising 63 lithium-iron-phosphate battery containers and involves an investment of $64 million.
In July 2026, ENGIE commenced commercial operations at the 25 MW/150 MWh BESS Arica project located in the Arica and Parinacota region, Chile. The project involves an investment of approximately $50 million. The project is connected directly to the Arica substation. Additionally, the project comprises 36 lithium-ion battery containers and nine conversion modules and can supply electricity equivalent to the consumption of over 18,000 homes for five hours.
