GasAndes Pipeline is an operating natural gas pipeline in Argentina and Chile.


The pipeline runs from La Mora, Mendoza Province, Argentina to San Bernardo, Chile, on the outskirts of Santiago, Chile.[1][2]

In 1991, Argentina and Chile concluded the Gas Interconnection Protocol. For the implementation of this protocol seven trans-Andean pipeline projects were proposed.[7] The GasAndes Pipeline project was proposed by the consortium of NOVA Corporation of Canada, Chilean companies Gasco and Gener, and Argentine companies Compañía General de Combustibles and Techint Compañía Técnica Internacional. The feasibility study for the pipeline was concluded in 1994, and the pipeline was commissioned in 1997.[2]

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.[7][8] In 2012, Argentina and Chile began discussing possible conversion of the GasAndes pipeline for 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.[7][8][9]

In 2018, Chilean power plant operator Colbún (owner of the Nehuenco and Candelaria power stations) signed a contract with Argentina's Compañía General de Combustibles to import up to 1.3 million cubic meters of gas per day, allowing Argentina to resume natural gas exports to Chile through the GasAndes pipeline for the first time in more than a decade.[8]

The GasAndes Pipeline, together with the NorAndino Gas Pipeline, has continued to play a key role in meeting shifting seasonal demand for natural gas in Chile and Argentina.[10][11] In April 2022, Argentine and Chilean government officials met with representatives of 10 leading oil and gas companies to discuss a fuel swap initiative that would send Vaca Muerta gas to Chile in the summer months via the GasAndes pipeline, while returning gas to northern Argentina in the winter months via the NorAndino Gas Pipeline.[11]

Technical features

The diameter of the pipeline is 610 mm (24 in), and its annual capacity is reportedly between 3.3 billion[2] and 3.94 billion[1] cubic meters. It was originally designed to export gas from Argentina's Neuquén gas fields. Total investment in the project was US$1.46 billion.[2]
