Gas transport involves transmission from the production sites to the consumption area to feed gas into the distribution networks there. The gas transport network can be compared to a motorway as it is made up of large axes, while the distribution networks are made up of shorter axes that route the gas directly to the consumer. At a national level, long-distance pipelines of the gas transport network efficiently connect the storage caverns or aquifers with the distribution networks. A key requirement for the smooth functioning of the infrastructure is information about the gas volumes that flow from one region to another or from one company to another.
