Mexico’s natural gas market continues to evolve rapidly. New pipelines are being built to move increasing volumes of U.S.-sourced gas to Mexican power plants, industrial customers and other end users. Gas exports from the U.S. to Mexico already average 4.5 Bcf/d and those volumes are sure to rise as more pipelines and power plants come online. Just as important, the government of Mexico has been taking aggressive steps to undo what had been state-owned Petróleos Mexicanos’s (Pemex) near-monopoly on gas pipeline capacity and to encourage a large and diverse group of gas marketers to enter the fray. Today, we examine ongoing efforts to increase transparency, pipeline access and competition in the gas market south of the border, and look at how Comisión Federal de Electricidad’s (CFE) marketing affiliate, CFEnergía, is growing its gas marketing business within Mexico.
