- This involves installing a battery energy storage system (BESS) at the 205 MW Las Salinas photovoltaic power plant, which currently operates alongside the 112 MW Sierra Gorda Este wind farm.
- The project will combine three technologies: solar, wind, and energy storage.
November 24, 2025 – Enel Chile, through its subsidiary Enel Green Power Chile, has initiated construction of the Las Salinas battery energy storage system (BESS), part of an industrial-scale hybrid renewable energy plant that combines three technologies: solar, wind, and storage.
Located on the same site as the Sierra Gorda Este wind farm and the Las Salinas photovoltaic plant, this new battery energy storage system (BESS) will have a capacity of 205 MW and can store energy from both plants for up to four hours.
This project, which aims to optimize the integration of renewable energy sources and enhance the resilience of the electrical system, is the first of three BESS systems planned for implementation in currently operating wind and solar facilities.
BESS systems are crucial in the electricity generation chain because they allow the production curve of renewable sources to be shifted, ensuring efficient delivery when needed.
With an annual storage capacity of 292 GWh, the Las Salinas BESS system equals 21% of the volume of the Rapel hydroelectric power plant reservoir, which can store 695 million cubic meters.
During the peak of construction, it is estimated that approximately 250 workers will be involved in various implementation tasks at the plant.
Furthermore, Enel Green Power highlights that the project will feature educational programs directed at the local community, consistent with its Sustainability and Community Relations policy.
The launch of this project marks a milestone for the company, reaffirming its dedication to the country's decarbonization efforts. The expansion of storage systems such as BESS will allow for more efficient integration of renewable energy sources, thereby enhancing the security and stability of the national electricity grid.
