In addition, natural gas is produced from domestic sources in the east of the country. The construction of a further LNG terminal on the Pacific coast in the south-west of the country is currently being planned. In total, the transport network stretches over more than 4000 km of pipeline, with differences in altitude of more than 2500.

A challenge for the Colombian grid operator are the large differences in gas quality, as the LNG imported by ship can differ significantly from the domestic source. In order to be able to correctly determine the energy supplied to downstream customers, a project to implement SmartSim was started in 2018. In this way, the gas quality can be tracked precisely throughout the country. The project, which is being carried out in cooperation with the Colombian Consultancy Firm Polygon Energy S. A., has a pioneering character because it is the first application of this kind in South America. The metrological evaluation of the method is carried out in accordance with the international standard ISO 15112 and the international guideline R 140 of the OIML.
