In brief

What this company does

Transportadora de Gas del Sur receives natural gas owned by a shipper, usually a natural gas distributor, at one or more intake points on its pipeline system and transports it for delivery to the shipper at specified delivery points along the system. Under applicable law and its License, it is not permitted to buy or sell natural gas except for its own consumption and to operate the pipeline system. The pipeline system connects natural gas fields in southern and western Argentina with distributors and other users of gas in those areas and in the greater Buenos Aires area. Natural gas transportation revenues accounted for 41% of its total revenues in the year ended December 31, 2025. In 2025, 74.2% of its average daily natural gas deliveries were made under long-term firm transportation contracts. Revenues derived from natural gas firm transportation contracts amounted to Ps. 567,936 million during 2025, representing 81% of the total revenues of its Natural Gas Transportation segment for that year. It is the technical operator of the GPM pipeline, including its two compressor plants, after ENARSA awarded it the operation and maintenance through a private tender on June 5, 2023, for a period of 5 years, extendable for up to 12 months.
