Regasification of LNG

Liquefied natural gas is injected into the national gas grid through the interconnection with LNG terminals in Panigaglia and Rovigo.

Highlights 2021

Daily regasification capacity maximum of LNG of the Panigaglia plant: 17,500 m3.

Maximum annual quantity of natural gas that can be released into the network for transmission: 3.5 bcm.

Transportation and dispatching

Natural gas in Italy reaches the single withdrawal points along the national gas transport system which is made by the national, regional and local pipeline networks.

Highlights 2021

  • 9 entry points of the National Network for natural gas coming from abroad: Tarvisio, Gorizia, Passo Gries, Mazara del Vallo, Gela, Melendugno and the LNG terminals in Panigaglia, in Rovigo (Cavarzere) and in Livorno (OLT).

  • Gas injected in the national network: 75.77 bcm.

  • Operating gas pipeline network: 32,767 km.


Gas storage enables a dynamic optimization of infrastructures with the aim of satisfying requests by system users.

Highlights 2021

  • 9 storage concessions: 5 in Lombardia, 3 in Emilia Romagna and 1 in Abruzzo.

  • Strategic storage capacity: 4.5 bcm.

  • Total storage capacity available: 12 bcm.

  • Gas volumes through the storage system: 18.86 bcm.

Natural gas pays a key role in the energy context, both Italian and European. In Italy Snam provides natural gas transport, dispatching, storage and regasification, ensuring national energy security.

Transportation network

Methane flows throughout Italy thanks to a pipeline network that spans for the whole Country. Thanks to Snam's specific know-how that designs infrastructure in equilibrium with the environment, pipeline transport guarantees high levels of security and environmental sustainability, avoiding inefficient and less reliable road transport.


To guarantee energy security, gas system has to face with ease possible demand sudden increase. For this reason Snam manages a storage system capable of storing gas during lower demand periods (i.e. Summer) and of supplying methane during periods of increased demand, deficiency or temporary interruption of imports. Gas storage is fundamental to manage fluctuations, linked to seasonal dynamics. In addition, it is a strategic solution against unforeseen events or demand's unexpected increases, engendered by particular atmospheric conditions.

LNG regasification

Once extracted, natural gas can be liquefied thorugh a specific cooling process (-160°), that leads to a considerable reduction of volume. Thanks to reduced volume occupied, LNG can be easily carried by LNG carriers. Liquefied Natural Gas represents a fundamental resource in terms of diversification of supplies and un connecting European countries with resources, which would be impossible to connect through pipeline.
