Similarly, the Camarones BESS in Coquimbo offers 200 MW / 1,000 MWh capacity, investing $350 million USD, scheduled to start operations by late 2026. The standalone system will include 315 containerized lithium-ion battery units and connect via 220 kV infrastructure. Meanwhile, in Tarapacá, the Nueva Pozo Almonte BESS will deploy lithium iron phosphate (LFP) technology with 762 MWh capacity and $157.5 million USD investment, set to begin construction in March 2026, underscoring the trend toward diversified battery chemistries.
Other projects like Los Ñisñiles (90 MW / 360 MWh, $64 million USD in Coquimbo) and Kallpa (57 MW / 285 MWh, $69 million USD in Antofagasta) complement this expansion, with Kallpa linked directly to a 344 MW wind farm, marking one of Chile’s initial integrated renewable-plus-storage facilities.
Data from early 2025 reveals over 6,800 MWh of new BESS capacity entered environmental review across 16 projects totaling 2,031 MW in power and $2.5 billion USD in investment nationwide. Leading projects like Kanut and Las Cañas propose large-scale storage exceeding 1,600 MWh, emphasizing Chile’s focus on long-duration storage to mitigate renewable intermittency and support the National Electric System’s stability. Collectively, these developments represent a decisive scaling of Chile’s storage infrastructure critical for accelerating its clean energy transition.
