The North Baja Pipeline is an overall 220-mile (350 km), bidirectional natural gas pipeline that can deliver gas from Arizona, through California, and into Mexico or from Mexico into the United States.
The 80-mile (130 km) U.S. portion of the system is owned by TC PipeLines LP, and the 140-mile (230 km) Mexican portion is owned by Sempra Energy International.
[1] North Baja Pipeline was originally conceived as an east-to-west pipeline to provide electric power plants in Mexico with natural gas.
The source of that natural gas is a liquefied natural gas terminal on the Pacific Coast of Mexico called Costa Azul (Energia Costa Azul), owned by a subsidiary of Sempra.
The pipeline is capable of transporting up to 600 million cubic feet a day of natural gas in either direction.
