Corporate Profile

Our Company

Transportadora de Gas del Sur S.A. started operations on December 28, 1992, upon the privatization of the Argentine energy sector. Nowadays, we are the major gas transportation company in our country, and conduct the operation of the most extensive pipeline system in Latin America. We are also leaders in natural gas liquids (NGL) production and commercialization both in the local and exports market - an activity performed from our General Cerri Complex, located in Bahía Blanca, province of Buenos Aires. Furthermore, we provide integral solutions related to natural gas, and link Producers’ activities to the market.

In 1998, we ventured into the telecommunications segment through our subsidiary TELCOSUR S.A. ("TELCOSUR"), becoming an important "carrier of carriers" in our operations area.

Quality Standards

In late 2001, we obtained the re-certification of our Environmental System under ISO 14,001 Standards, as well as the certification of our Quality Management System under ISO 9,001 Standards. Both qualifications enable us to be the first company in the regulated gas sector to integrate both systems. Furthermore, in the year 2006 we honored our commitment to continuous improvement outlined in our Policy of Quality, Environment and Safety and Occupational Health, by obtaining the certification under OHSAS 18,001 standards
