Overview
- The Ministry of Economy published Resolutions 1976 and 1977 in the Boletín Oficial on Friday, November 13, 2026, formally approving the adhesion of Procesadora de Gas del Sur (PGS) and Midstream de Gas del Sur (MGS) to the RIGI regime.
- Together the projects list USD 3.244 billion in qualifying investment, with PGS declaring USD 1.3947 billion to expand Tratayén processing capacity to 1,200 million cubic feet per day and MGS declaring USD 1.8496 billion for a 577 km, 20-inch poliduct and a 90,000 barrels‑per‑day fractionation plant.
- ARCA will assign special CUITs and apply tax and customs benefits under RIGI, MGS secured a formal request to freely dispose of export dollars under Article 198 while PGS did not, and both firms can import approved capital goods duty-free.
- Both firms began construction in May 2026, must meet staged investment milestones with hard deadlines in 2027, and target a start of operations on February 1, 2030 with an estimated 30-year useful life.
- The projects are part of TGS’s NGL program and involve partners and stakeholders tied to TGS’s control group; the approvals are meant to boost export capacity from the Neuquén basin and affect Argentina’s foreign‑exchange earnings and local supply chains through a 20% local‑sourcing commitment.
