Two consortiums bid for Chile’s Kimal–Lo Aguirre HVDC line [free access]

October 8, 2021

Two consortiums have submitted bids to compete in the international tender for the Kimal–Lo Aguirre high voltage direct current (HVDC) project in Chile.


The first consortium, known as Yallique, has been proposed by China Southern Power Grid International (CSGI) HK, which is integrated by the Colombian ISA Interchile and CSGI. The second bidder is the Meval consortium formed by Iberdrola Redes España, S.A.U and Celeo Redes Chile Limitada.


The Kimal–Lo Aguirre is a 1,500-km, ±600 kV line that will link Antofagasta and Santiago, with a transmission capacity of 2,000 MW. The project will require an estimated USD1.48 billion.


Chile has set a goal of total withdrawal of coal plants before 2040. The HVDC project is necessary, as it will take advantage of the energy being produced from the upcoming renewable energy projects in northern Chile, which due to the current congestion of transmission lines, are not being utilised at their full capacity.


The HVDC project will run parallel to the existing 500 kV alternating current (AC) corridor and facilitate the decarbonisation process that is currently underway.


The construction works are expected to begin 2022 and end by end-2028.
