What Transportadora de Gas del Sur does

Transportadora de Gas del Sur S.A. (TGS) is Argentina's largest natural gas transportation company and the principal midstream operator connecting the Vaca Muerta shale basin to consumption centers. Founded in 1992 following the privatization of Gas del Estado, TGS operates a regulated pipeline network of more than 9,248 km across seven provinces, transporting approximately 60% of Argentina's natural gas consumption through firm and interruptible transportation services priced under tariffs set by ENARGAS pursuant to Law No. 24,076. The company has been listed on the NYSE since 1994 (ticker: TGS) and is co-controlled by Pampa Energía S.A. and the Sielecki family, with CIESA holding 53.83% of share capital.

TGS operates five integrated business lines: (1) Transporte — regulated natural gas transportation with 32 compressor plants and 772,100 HP of installed power; (2) Líquidos — natural gas liquids processing, fractionation, storage, and dispatch at the Complejo General Cerri in Bahía Blanca, producing over 40% of Argentina's ethane and 28% of national LPG, with annual capacity exceeding 1.1 million tonnes and an export terminal at Puerto Galván serving five continents; (3) Midstream — gas gathering, treatment, and compression services in Vaca Muerta via a 183 km gathering pipeline and three plants (Tratayén, Río Neuquén, Plaza Huincul) with 60 MM m³/d of injection capacity, making TGS the first midstreamer in the basin; (4) Telcosur — telecommunications over 4,600 km of radio link and 3,570 km of optical fiber serving Oil & Gas companies, carriers, cooperatives, and ICTs; and (5) Integra — integrated construction, operation, maintenance, turbomachinery repair, and flow laboratory services for third-party Oil & Gas assets.

TGS earns revenue through subscription-based firm transportation capacity fees, usage-based interruptible transportation charges, transaction fees on liquids processing and export, and professional services fees. The customer base spans Argentine natural gas distributors (serving 6.2 million indirect end-users), power generators, industrial users, and upstream producers (YPF, Pluspetrol, Chevron, Shell) operating in Vaca Muerta. The company employs approximately 1,100-1,200 people across more than 35 installations. Two major growth projects are underway: a $550-560 million expansion of the Perito Moreno Gas Pipeline adding 14 MMm³/day by winter 2027 (RIGI-approved), and the $3 billion NGLs Project in Vaca Muerta targeting 2030 commercial operations and $1.2 billion in projected annual exports, with YPF, Pluspetrol, and Chevron committed to over 80% of project capacity.
