Transport
Natural gas is taken over at delivery points located in connection with import lines, regasification plants, and production and storage centres in Italy, and is transported and then delivered to redelivery points connected to local distribution networks and to large industrial and thermoelectric users.
The correct flow of gas in the pipelines is ensured by 13 Snam Rete Gas compression plants, located along the national network, and by a management and control structure consisting of 8 Districts, which supervise and control the activities of 48 Maintenance Centres distributed throughout the country, and a Dispatching Centre that remotely monitors and controls the transmission network and coordinates the compression plants.

Storage
The storage system makes it possible to compensate for the different needs between gas supply and consumption, guaranteeing continuity of service during periods of gas demand peak (typically in the winter period) and gas storage (usually in the summer period).
Snam, through its subsidiary Stogit, is the largest storage operator in Italy and one of the largest in Europe. The Group manages a total of 9 plants that act in synergy with the Company’s other transport and regasification infrastructures, contributing to the country’s energy security.

Regasification
The regasification activity consists in returning to its original state the gas previously extracted from the fields and liquefied at a temperature of -160°C to allow it to be transported on LNG carriers. After regasification, the gas is fed into the national transmission network.
Snam, through GNL Italia, operates the Panigaglia (La Spezia) plant, the first operational regasification plant built in Italy, in 1971.
