TGS, which is partly owned by energy company Pampa Energia SA, announced the project during an event in New York in March. It includes new gas processing facilities at an existing plant in Tratayen, near the Vaca Muerta shale basin, a 573-kilometer pipeline to Bahía Blanca on Argentina’s Atlantic coast, and export facilities. The company has said it plans to seek incentives under President Javier Milei‘s RIGI investment regime, which offers tax and foreign-exchange advantages for large projects.
