Background

Construction of the pipeline started in March 2001. It was completed in November 2002 and inaugurated by the presidents of Uruguay and Argentina, Jorge Batlle Ibáñez and Eduardo Duhalde. The main pipeline, constructed at a cost of US$150 million, is approximately 215 km in length and has a capacity of 5 million cubic meters of natural gas per day (1.825 billion cubic meters per year). Additional branches of the pipeline bring its total length to 400 kilometers. The offshore section crossing the River Plate between Punta Lara (Argentina) and Santa Ana (Uruguay) measures 55 kilometers in length, with the remainder of the pipeline running onshore through the departments of Colonia, San José, Canelones y Montevideo in Uruguay. The pipeline ranges in diameter from 18 to 24 inches.

Proposed extension to Brazil

The pipeline is supplied from Argentina's gas fields in the Neuquén Basin. An increase in Argentine fossil gas production made possible by completion of the first phase of the Néstor Kirchner gas pipeline in mid-2023 has spurred interest in the possibility of extending the Southern Cross pipeline to export Argentine gas into southern Brazil. The 920-kilometer pipeline extension would include some 415 kilometers (258 mi) of pipe to be laid in Uruguay and 505 kilometers (314 mi) in the Brazilian state of Rio Grande do Sul. In Brazil, the new pipeline extension would connect with the existing Gasbol gas pipeline. The proposed pipeline would also require the construction of several new compressor stations.

Proposed Extension to Brazil: Location

The proposed extension would run from Colonia del Sacramento or Montevideo, Uruguay to a junction with the Gasbol Gas Pipeline near Porto Alegre, Brazil.
