The proposed South Texas-Tuxpan Gas Pipeline is a joint venture between TransCanada (60%) and Sempra Energy’s Mexican unit IEnova (40%), also known as Infraestructura Marina del Golfo (IMG), which is building the pipeline.[4] The $3.1bn project is being developed by the Federal Electricity Commission (CFE) of Mexico, and will become the country’s first undersea pipeline upon completion. Construction began in the port of Altamira, Mexico, in May 2017, and is scheduled to be complete by late 2018.[5]

The pipeline began service in early 2019.[6]


In August 2017, members of the Yaqui tribe in the town of Loma de Bacum used a backhoe truck to remove a 25-foot segment from the 30-inch-thick pipeline, effectively halting production. Loma de Bacu had previously previously refused to grant its consent to the pipeline.[7]
