Snam's presence in transmission in Italy
Through the subsidiaries Snam Rete Gas and Infrastrutture Trasporto Gas, Snam is the leading Italian natural gas transportation and dispatching operator, and owns almost all of the transportation infrastructure in Italy, with 32,625 kilometres of high- and medium-pressure gas pipelines (approximately 93% of the entire transmission system). Snam manages the gas pipeline network via 8 districts, 48 maintenance centres throughout Italy, 13 compression stations, including the two new plants of Minerbio and Sergnano that were commissioned in 2018, and a new dispatching unit that has been recently renovated in terms of structure and technology. The gas coming from abroad is fed into the network at the seven import channel, corresponding to the interconnections with the import pipelines and LNG regasification terminals. Once it has been imported or regasified, the gas is transported to the local distribution networks, the regional network redelivery points or large end users such as thermoelectric power stations or manufacturing plants.
Snam awards transportation capacity to applicant shippers. In this way, users acquire the right to feed or withdraw, on any day of the thermal year, a quantity of gas not exceeding the daily flow rate. The conditions for access to the service are contained in the Network Code. The shippers have the possibility to make sales and gas exchanges at a Virtual Trading Point (PSV) of the National Network, thanks to the dedicated IT platform.
