Gasoducto Rosarito consists of 302 kilometers of natural gas pipeline in Baja California owned by IENova S.A.B. de C.V. (which is in turn owned by Sempra Energy International). It connects to 80 miles of pipeline in the United States owned by TC PipeLines, called the North Baja pipeline. There is no co-ownership of the U.S. or Mexican portions of the system, but TC PipeLines and Sempra Energy International have an agreement that defines how the pipeline is operated.[1]

The pipeline is a bi-directional system divided into three segments.[3]

The main pipeline, in operation since 2002, is 30 inches in diameter with a capacity of 534 million cubic feet per day (15.1 million cubic meters per day, or 5.5 billion cubic meters per year). It begins at an interconnection with El Paso Natural Gas Co. near Ehrenberg, Arizona, crosses the Mexican border at Algodones, Baja California, and heads west across northern Baja California, terminating at an interconnection with the Transportadora de Gas Natural de Baja California (TGN) Pipeline south of Tijuana. The second section, known as LNG Spur and in operation since 2008, is 42 inches in diameter, with a capacity of 2600 million cubic feet per day. It starts at the Costa Azul LNG terminal north of Ensenada, Baja California and intersects with the main line near El Carrizo, south of Tecate, Baja California. A third 72-kilometer section, known as Yuma Lateral, has a diameter of 12 inches and a capacity of 190 million cubic feet per day.[4]
