Chile’s President Attends Inauguration of 3.5GWh BESS at Grenergy’s Oasis De Atacama Solar-Plus-Storage Complex

Why It Matters

The expansion solidifies Chile’s position as Latin America’s leading market for large‑scale solar‑plus‑storage, attracting significant capital and enhancing grid flexibility. It also demonstrates the scalability of hybrid renewable models for other emerging markets.

Key Takeaways

• Grenergy inaugurated 3.5 GWh BESS at Oasis de Atacama Phase 6
• Targeting 14 GWh storage and 2.1 GW solar by 2028
• Chile remains Grenergy’s largest market with $2.8 bn invested
• BYD supplied 6,240 containerised MC Cube T units for the BESS
• Grenergy plans $2 bn additional Chile investment over next two years

Pulse Analysis

Chile’s Atacama Desert continues to attract megaprojects that blend abundant solar irradiance with cutting‑edge battery storage. The recent inauguration of Grenergy’s 3.5 GWh BESS, featuring 6,240 BYD MC Cube T containers, highlights how developers are turning the region into a testbed for dispatchable renewable power. By pairing storage with solar, the project mitigates intermittency, supports peak‑hour demand, and provides a template for other high‑insolation markets.

Grenergy’s Oasis de Atacama complex is scaling aggressively, moving from an initial 2 GW solar footprint toward a 2.1 GW/14 GWh hybrid configuration by 2028. The $270 million financing secured last September and the broader €3.5 billion (≈$3.9 billion) investment plan signal strong confidence from global capital providers. The phased roadmap, which doubles Elena’s storage capacity to 7 GWh by 2028, reflects a strategic shift toward longer‑duration batteries that can smooth daily and seasonal variability, a critical capability as Chile’s grid integrates more renewables.

Regionally, the development reinforces Latin America’s accelerating storage build‑out, drawing interest from investors such as KKR and CVC DIF, and prompting policy dialogues ahead of the Energy Storage Summit Latin America 2026. As Chile targets an additional $2 bn of renewable investment, the country’s regulatory environment and financing frameworks are likely to evolve, offering a blueprint for neighboring markets seeking to replicate the solar‑plus‑storage model. The convergence of abundant resources, supportive policy, and robust financing positions Chile as a catalyst for the continent’s clean‑energy transition.
