The project’s influence zones extend beyond Biobío into Quilleco commune and Yungay in Ñuble region due to noise, vibration and atmospheric emissions impacts, giving the development interregional classification status. This designation requires broader environmental analysis covering biodiversity, air quality and human settlement factors across multiple administrative jurisdictions. The technical design incorporates a step-up substation, a 220 kV transmission line spanning 3.84 kilometers, and sectioning infrastructure to connect with Chile’s National Electric System.
Preliminary scheduling indicates construction commencement in August 2027 with completion targeted within 24 months. The construction phase encompasses road enablement, work camp installation, concrete plant construction, foundation excavation, turbine assembly and transmission line installation. Peak workforce requirements reach 753 personnel during construction, averaging 346 monthly positions across the two-year build period. Permanent works will occupy 105.4 hectares of primarily forestry-designated land selected for favorable wind conditions and proximity to existing transmission infrastructure.
The operational phase extends 35 years following commissioning planned for July 2029, with projected annual generation around 800 GWh at an estimated 25 percent capacity factor. A subsequent 12-month closure period provides for facility decommissioning and land restoration activities. The project represents one of Chile’s three largest environmental submissions by investment value in 2026, trailing only mining expansions at El Abra ($7.5 billion) and Escondida ($5.15 billion), establishing it as the year’s most significant greenfield renewable energy development.
Climate risk assessment identifies high and very high threat levels related to temperature and precipitation changes affecting flora and fauna in Los Ángeles, Quilleco and Yungay, alongside rural water security concerns amid increasing drought frequency. The selection of forestry land with adjacent transmission access aims to minimize new linear infrastructure requirements and reduce environmental footprint compared to alternative sites.
