The report details four lithium-ion battery energy storage systems (BESS) in the testing phase as of March 2025, all connected to the grid. These include Grenergy’s 95 MW/586 MWh Quillagua I PFV project in María Elena, Antofagasta; Engie’s 48 MW/264.2 MWh PFV Capricornio initiative, also in Antofagasta; WEG Capital’s 60.5 MW/121 MWh PFV María Elena facility in the same region; and Pacific Hydro’s 3 MW/6 MWh PE Punta Sierra pilot BESS in Ovalle, Coquimbo. A Ministry of Energy spokesperson stated: “These projects demonstrate Chile’s leadership in integrating advanced storage solutions to support renewable energy.”
Most of these systems are located in Antofagasta, a key region for solar and wind power, where storage helps manage grid stability and reduce energy curtailment. The testing phase is critical for ensuring these systems perform reliably under real-world conditions, paving the way for broader adoption. The Punta Sierra pilot in Coquimbo marks an early step toward expanding storage solutions beyond Antofagasta.
Chile’s energy storage boom is driven by the need to optimize intermittent renewable sources like solar and wind. By storing excess energy during peak production and releasing it during high demand, these systems enhance grid flexibility and efficiency. Energy Minister Diego Pardow noted: “Energy storage is one of the most dynamic sectors in recent years, offering significant opportunities for clean energy integration.” The growth is supported by declining costs of lithium-ion battery technology and Chile’s abundant renewable energy potential.
The Ministry’s report underscores Chile’s strategic focus on sustainable energy development. With additional projects under construction and in planning, the country is on track to meet its 2030 goal, strengthening its position as a leader in Latin America’s energy transition. These efforts contribute to economic growth and environmental sustainability by reducing reliance on fossil fuels and supporting clean energy adoption.
