The Snam Group in 2015 GRI - G4: 3, 4, 6, 7, 8, 9
As an integrated operator in gas infrastructure management, the Snam Group is active in the transportation and dispatch, storage and distribution of natural gas and the regasification of liquefied natural gas, carried out, respectively, through four operating subsidiaries wholly-owned by Snam S.p.A.: Snam Rete Gas, GNL Italia, Stogit and Italgas.
The scope of consolidation changed in 2015, with Acam Gas S.p.A. added in April after Italgas bought the remaining 51% stake in the company that it did not already own. As such, Italgas S.p.A. became the owner of 100% of Acam Gas S.p.A.’s share capital with effect from 1 April 2015.
The situation compared with 30 June 2014 also changed as a result of the consolidation in July 2014 of Gasrule Insurance Ltd and A.E.S. Torino S.p.A., respectively wholly-owned subsidiaries of Snam S.p.A. and Italgas S.p.A.

Transportation |
Snam Rete Gas manages the gas pipeline network via 8 districts, 48 maintenance centres throughout Italy, 11 gas compression stations and a dispatching unit. |
In transportation, the natural gas is loaded at delivery points connected to the import lines (Russia, northern Europe and North Africa), the regasification plants and the gas production and storage centres distributed throughout Italy. The gas is then transported for delivery, based on customer directions, to redelivery points connected to local distribution networks and to major industrial and thermoelectric consumers. |

Regasification |
GNL Italia manages the regasifier in Panigaglia (La Spezia), the first plant of its kind, which was built in Italy in 1971. |
Regasification is the final activity in the liquefied natural gas (LNG) chain and involves taking gas extracted from deposits and then liquefied at -160°C back to its original state for transportation on purpose-built ships. In the gas system, the LNG chain thus enables diversification of supply sources. |

Storage |
Stogit manages nine storage fields in Lombardy, Emilia-Romagna and Abruzzo, under concession. The fields comprise deposits, wells, pipes, processing plants and compression stations. Stogit also manages an operational dispatching system. |
Natural gas storage involves injecting the gas into the porous rock of an empty gas field, thereby essentially restoring the field to its original state. Once it has been stored, the gas can be reinjected into the transport system and delivered in accordance with demand from the market. Storage enables the difference between gas supply and demand to be offset, thereby ensuring continuity of supply. |

Distribution |
Italgas, with its subsidiaries Napoletanagas, A.E.S and Acam Gas, manages an integrated system of infrastructure, mainly self-owned, comprising gas withdrawal stations, local pipelines, pressure reduction plants and redelivery points where gas meters are installed. |
The distribution service involves carrying gas from the transportation network connection points to the end-user redelivery points. It is conducted on behalf of companies authorised to sell gas. The system is overseen, 24/7 and 365 days a year, by the Integrated Supervision Centre. |
