Transportadora de Gas del Sur S.A. (NYSE: TGS) is a leading Argentine energy infrastructure company specializing in the transportation, processing and commercialization of natural gas and natural gas liquids (NGL). The company’s core business activity is the ownership and operation of an extensive pipeline network that delivers natural gas from producing fields in the Neuquén Basin and Golfo San Jorge to major demand centers in the Greater Buenos Aires area, central Argentina and export interconnections with neighboring countries.
In its transportation segment, TGS manages over 7,000 kilometers of high-pressure pipelines equipped with compressor stations and measurement facilities. Through long-term capacity contracts, the company ensures reliable gas flow for electric power generators, industrial users and local distribution companies. TGS also supplies cryogenic services for the handling of liquefied gases and operates key extensions that connect Argentina’s gas system to Chile via the Norandino pipeline.
The company’s gas processing division includes two gas treatment plants near Bahía Blanca and General Cerri, where raw natural gas is separated into methane and valuable NGL by-products such as ethane, propane, butane and natural gasoline. TGS markets these by-products domestically and for export, offering fractionation, storage and transportation solutions. In addition, the company provides turnkey engineering, maintenance and technical consultancy services for mid-stream natural gas facilities.
Founded in 1992 following the privatization of the former state‐owned Gas del Estado, TGS is majority-owned by Tecpetrol, a subsidiary of the Techint Group. Governed by a board of directors under Argentine corporate law, the company’s executive leadership focuses on asset modernization, regulatory compliance and environmental stewardship. With a multi-decade track record, TGS continues to play a critical role in Argentina’s energy supply chain and regional gas markets.
