Complementary infrastructure on TGN’s existing system will extend benefits beyond the trunk route. The company plans 147 kilometers of 30-inch parallel loops across Córdoba, Santa Fe, Catamarca, Santiago del Estero and Tucumán, alongside 71,000 horsepower distributed across five compressor plants. These upgrades will add up to 14 million cubic meters daily to system capacity, directly serving industrial facilities and thermal power plants in Santa Fe and the Litoral region. The provincial government views the expansion as critical for energy cost competitiveness after industries absorbed sharp LNG import cost increases during the 2026 winter, when delivered BTU prices jumped from US$11 to US$26 due to Middle East supply disruptions.
TGN CEO Horacio Pizarro stated the project will transform Vaca Muerta gas into competitive energy through domestic production, import substitution and exportable surplus generation. The company projects annual savings of US$700 million through reduced imports of LNG and diesel, while regional gas exports to Chile, Brazil, Bolivia and Uruguay could generate US$450 million yearly in foreign exchange. TGN holds the only Argentine gas network connected to all four neighboring countries. Peak construction activity will require approximately 2,000 workers.
The commercial process opens with a capacity tender in late September 2026, followed by offer submission and award scheduled for late November. Santa Fe will benefit from enhanced pipeline capacity addressing structural supply constraints that have affected the province’s manufacturing base and power generation sector, with the provincial government simultaneously implementing financing programs to help industries manage elevated energy charges during the transition period.
