Strategic Initiatives
Growth programs, investments, and their expected impact
An expansion project to increase natural gas transportation capacity by 14 million cubic meters per day from the Vaca Muerta formation (Tratayén) to Salliqueló, helping replace energy imports and boost domestic supply.
Expected impact: Adds 14 MMm³/d of incremental transport capacity, reinforcing TGS's dominant position in Argentine gas midstream and driving long-term regulated revenue growth.
A massive strategic initiative aimed at monetizing hydrocarbon-rich gas from Vaca Muerta through the separation, transportation, and fractionation of natural gas liquids (propane, butane, ethane, and natural gasoline). The project includes conditioning facilities in Tratayén, a 573-km mixed-product pipeline, and a fractionation plant in Bahía Blanca.
Expected impact: Positions TGS as a regional leader in NGL industrialization, projected to generate approximately USD 1.2 billion in annual export revenues upon completion.

TGS selected German industrial engineering firm Gizil to deliver its 'Virtual Plant' digital solution. This innovative alternative to conventional 3D CAD/BIM digital twins uses reality capture and metadata integration to improve operational efficiency, safety, and asset management across TGS's compressor stations and facilities.
