Overview
- The Energy Secretariat formalized the award via Resolution 397/2025, with TGS the sole bidder in the July 28 tender.
- Works include new stretches between Tratayén and Salliqueló, three compressor plants totaling 90,000 HP, and reinforcements on TGS’s network to route gas to Greater Buenos Aires and the Litoral.
- Transport capacity will rise from 21 to 35 million cubic meters per day, with an optional second phase contemplated for a further 6 million.
- TGS will run an open contest to allocate the incremental capacity before construction mobilizes, consistent with free-access rules.
- Timing remains uncertain, with company statements and some reports pointing to winter 2026 and others to winter 2027; officials project trade and fiscal savings of about $700 million and $450–500 million a year, supported by roughly 20 new wells and added conditioning investments.
