Shorthaul is a custom service offered by GTS to feed gas into a specific entry point and withdraw gas from a specific exit point of the GTS network only. The distance between the entry and exit points can be 50 km at the most (as the crow flies). The shorthaul service is registered in a separate portfolio and the hourly volume of gas fed in needs to be the same as the volume withdrawn. Shorthaul has a minimum contract period of three years and a maximum contract period of 7 years.
