Solar and BESS Plant Estepa I & II

Estepa represents the largest financing deal in Atlas's history — and a bold answer to one of Chile's biggest energy challenges. By combining solar power with massive battery storage in the sun-soaked Antofagasta region, Estepa will capture clean energy during the day and release it when the grid needs it most, helping ease the curtailment that has long troubled Chile's renewable sector. Once complete, it will generate enough clean power for more than 250,000 households. Estepa is under construction, with commercial operation expected by the end of 2026.
