Enel initiates EIA for Chile‚ÄďArgentina link [free access]

October 18, 2021

Chilean electric company Enel Generación has submitted the environmental impact assessment (EIA) for the international electrical interconnection project between Chile and Argentina to the country’s Servicio de Evaluación Ambiental or the Environmental Evaluation Service (SEA). The EIA will cover all the activities or works located in Chilean territory, starting from the new Los Cóndores substation to the tower closest to the international border with Argentina.

 

The objective of the assessment is to ascertain the environmental impact of a 500 kV transmission line that will allow electricity exchange between the Chilean and Argentine electricity systems. The interconnection project is estimated to require an investment of USD36 million.

 

The Chilean section of the cross-border link includes the construction of the new 220/500 kV gas-insulated switchgear (GIS) Los Cóndores substation, 2x220 kV Los Cóndores–Ancoa line, and a 26.7-km, 500 kV single-circuit line connecting the new Los Cóndores substation to the border with Argentina, from where it will run 287 km to the Río Diamante substation. In addition, the Rio Diamante substation will also be expanded to accommodate the new line.
