The project is Chile’s first large-scale stand-alone energy storage system and the largest in Latin America.
Chile’s clean energy development took a major step forward with the launch of Latin America’s largest battery-based energy storage system.
Atlas Renewable Energy’s Desert BESS project, the first large-scale stand-alone system project in Chile and Latin America, is located on public land in the municipality of María Elena in the Antofagasta region.
Energy Minister Diego Pardow attended the system’s inauguration, where he remarked that the project represents concrete progress on Chile’s energy transition by integrating technology that lends greater stability to the national electricity system.
This excellent news also positions Chile as a leader in regional energy innovation and storage solutions.
The battery storage system
The system stores energy during high solar generation and reinjects it into the grid at high-demand times.
Importantly, it operates on a stand-alone model that allows for autonomous, decentralized operation, facilitating flexible integration with other renewable sources.
The system has a total installed capacity of 200 MW and a storage capacity of 800 MWh, equivalent to four hours of continuous discharge.
Its capacity is equivalent to the electricity consumption of approximately 122,000 homes. In addition, it can deliver energy autonomy equivalent to 2,500 electric buses or cover more than 500,000 kilometers, more than 100 times the length of Chile.
Project scope and projections
The system will reinject about 280 GWh annually into the national electricity system.
These storage systems are vital in transitioning to a cleaner, more resilient energy matrix, especially in areas with high solar generation.
