TGI Pipeline Network is a gas pipeline network in Colombia.

Location

Starting from the Ballena gas fields along the Caribbean coast in Colombia's northeastern department of La Guajira, TGI's gas transportation network extends south through Barrancabermeja, then branches off at the hubs of Vasconia and Mariquita and spreads throughout Colombia's interior. The pipeline stretches as far west as Cali (Valle del Cauca department); as far south as Neiva (Huila department); and as far east as the gas fields of the Llanos Orientales basin near Yopal (Casanare department).

Project Details

• Operator: TGI (Transportadora de Gas Internacional SA)
• Owner: Grupo Energía Bogotá
• Current capacity: 733.8 million cubic feet per day
• Length: 4,033 km
• Status: Operating
• Start Year: 1997

Background

Colombia's Transportadora de Gas Internacional S.A. E.S.P. (TGI) - a division of Grupo Energía Bogotá - engages in the operation and maintenance of a natural gas pipeline system, comprising more than 4,000km of pipelines and 16 gas compression stations with a total combined capacity of 195,000 HP.

The TGI network comprises three main gas pipelines, to which regional branches are connected.

The three main segments of pipeline are:

• Ballena to Barrancabermeja (771 km)
• Barrancabermeja to Bogotá and Neiva, also known as the Centro Oriente pipeline (1143 km)
• Mariquita to Cali (797 km)

TGI acquired the latter pipeline from Transgas de Occidente S.A. in 2017.

Additional segments of the pipeline network are as follows:

• Boyacá to Santander (305 km)
• Cusiana to La Belleza (406 km)
• Morichal to Yopal (13 km)
• Cusiana to Apiay to Usme (409 km)
• De la Sábana (150 km)
• Bolívar/San Vicente (51 km)

TGI supplies natural gas to residential, industrial and commercial end-users, including Colombia's main cities (Bogotá, Medellín, and Cali). TGI was founded in 2007 after the EEB group acquired the state-run Ecogas's assets.

Recent projects have focused on expanding capacity along TGI's Cusiana-Apiay-Ocoa and Cusiana-Vasconia pipelines.

Capacity Expansion Plans

A January 2020 report from Colombia's energy planning agency UPME calls for several capacity expansions to the TGI Pipeline Network, including:

• enhancement of infrastructure on the Yumbo-Vasconia section of the pipeline to accommodate bidirectional flow of 250 MMcfd; this expansion is to be completed by January 2024, in anticipation of the commissioning of the new Buenaventura-Yumbo Gas Pipeline, which will bring in imported natural gas from Colombia's Pacific coast to Yumbo, just north of Cali.
• enhancement of infrastructure on the Ballena-Barranabermeja section of the TGI pipeline to accommodate bidirectional flow of 100 MMcfd by January 2021.
• construction of a new 170-MMcfd bidirectional connector linking the Ballena-Barrancabermeja segment of the TGI pipeline with the Ballena-Barranquilla segment of the Promigas Pipeline Network, to be completed by January 2021.
• enhancement of infrastructure on the Mariquita-Gualanday section of the pipeline to accommodate flow of 20 MMcfd by March 2022.
