The firm has bought the portfolio for $38 million (£26.8m) after reaching an agreement with Atacama Energy and Lader Energy.
The portfolio consists of a 77MW wind farm and 551MW of projects under development.
Commercial operations of the projects are expected to start by 2025.
Miguel Stilwell de Andrade, EDPR and EDP Group Chief Executive Officer, said: “We are committed to playing an active role in the energy transition and in the Latin American markets, where Chile offers world-class renewable energy generation potential.”
Chile has set out a target to generate 20% of its power from non-hydro sources by 2025 and 70% by 2050.
