The Nor Andino Gas Pipeline is an operating natural gas pipeline in Argentina and Chile.[1]


The pipeline runs west from the Pichanal natural gas compressor station in Argentina's Salta province, passing through Tres Cruces (Jujuy province), crossing the Argentine-Chilean border at Paso de Jama, and continuing through the Antofagasta region to Engie's Tocopilla and Mejillones power stations and the Mejillones LNG Terminal on Chile's Pacific coast.[1][2][3]

The pipeline was originally designed to transport natural gas from northern Argentina to Chile. However, starting in 2004, Argentina began reducing gas exports to Chile due to insufficient supply, and by 2007 gas transport through the pipeline had been completely halted.

In 2012, Argentina and Chile began discussing possible conversion of their trans-Andean pipelines to permit bi-directional flow. By 2016 the two governments had developed scenarios calling for Chile to export natural gas received at its Mejillones LNG Terminal and Quintero LNG terminal to the Argentine provinces of Salta and Mendoza, respectively, during the winter months, while Argentina would ship natural gas from its own production to Chile during the summer. The two pipelines identified as the best candidates for this initiative were the Nor Andino Gas Pipeline in the north and the GasAndes Pipeline in the south.[3][5][6]

In December 2017, Engie Energía Chile and Argentina Energy Consulting Services (ECS) became the first private companies to take advantage of the Nor Andino Pipeline's new bi-directional capacities. Under the terms of their agreement, ECS would export up to 2.5 million cubic meters of Argentine natural gas per day for use in Engie's Chilean operations through May 15, 2018; after that date, and within 240 days of its initial shipment, ECS would reimport an equivalent volume of gas from Chile.[7]
