Engie Chile Advances Construction of First Wind-Integrated Battery Storage System BESS Kallpa

Engie Chile’s BESS Kallpa project, linked to the 344 MW Parque Eólico Kallpa in Taltal, Antofagasta, has reached 44% completion. The $69 million investment will deploy a 57 MW/285 MWh battery system using 70 lithium-ion battery containers providing up to five hours of energy autonomy, equivalent to the average consumption of 34,000 households for the same period. This battery storage will connect directly to the wind farm’s substation and is planned to be operational by late 2026. The system is designed to optimize continuous renewable energy injection, contributing to the stability and reliability of the national electric system (Sistema Eléctrico Nacional).

Juan Villavicencio, CEO of Engie Chile, emphasized that BESS Kallpa represents a critical element in integrating renewable generation with storage solutions, enhancing flexibility and resilience in the electric grid. Engie views this as a strategic move toward a secure and sustainable energy transition, particularly in Antofagasta, where the company has maintained a significant presence.

BESS Kallpa complements Engie’s robust Chilean portfolio of battery projects, which includes BESS Arica (34 MW/170 MWh), BESS Tocopilla (116 MW), BESS Lile (140 MW), BESS Los Loros (46 MW), and the combined photovoltaic and storage facility Libélula (151 MWp + 199 MW). Currently, Engie operates 267 MW of battery storage capacity in Chile. Globally, the company advances hybrid projects combining renewable generation and storage, leveraging international expertise to build more resilient and efficient energy systems. These developments align with national and international objectives for energy transition and grid modernization.
