Transoccidente operates a pipeline in the Cauca Valley in Colombia. Transoccidente has a capacity of 69 mmcfd.
Transoccidente was established in 1998 as a result of a spin-off overseen by the Colombian Regulatory Commission for Energy and Gas. Because of the spinoff and since it began to operate after the public services law was issued in 1994, Transoccidente does not have a concession agreement for its operation.
Transoccidente's customers are Gases de Occidente, an LDC owned 70.1% by Promigas, and Cartones de America.
Promigas provides operations and maintenance services for Transoccidente under a long-term cost-plus contract which includes incentives for shared services.
