Background on the Kimal-Lo Aguirre Megaline Project

The Servicio de Evaluación Ambiental (SEA) in Chile has given a crucial green light to the Kimal-Lo Aguirre megaline project, bringing it closer to obtaining its Resolution of Environmental Qualification (RCA). This extensive undertaking, valued at approximately 1.5 billion US dollars, aims to connect Antofagasta and Santiago using high-voltage direct current (HVDC) technology for the first time in Chile. The project is pivotal for the country’s decarbonization efforts.

Project Details and Impact

The Kimal-Lo Aguirre megaline spans over 1,346 kilometers across five regions: Antofagasta, Atacama, Coquimbo, Valparaíso, and the Metropolitan Region. This high-tension electric transmission line project is the largest evaluated by the SEA in terms of extent. It will require nearly 5,000 permits during construction, creating more than 6,200 jobs in the process.

Regulatory Process and Next Steps

Since the project spans multiple regions, it will bypass the Comisión de Evaluación Ambiental (Coeva) and instead be reviewed by the Dirección Ejecutiva. The SEA’s executive director, Valentina Durán, is expected to issue the RCA shortly. Once approved, the project will proceed with securing the necessary permits and initiating construction.
