TRANSPORT

Also in 2020, a year characterized by difficulties and uncertainties due to the pandemic, Snam has demonstrated its essential role in guaranteeing the security of energy supplies

Snam, through its subsidiaries Snam Rete Gas 32,647 and Infrastrutture Trasporto Gas, is the leading km Italian natural gas transportation and dispatching Trasportation operator, and owns almost all the transportation network infrastructures in Italy, approximately 94% of the entire transportation system. 9,649 22,998 Snam manages the gas pipeline network via 8 districts, 48 km km maintenance centres throughout Italy, 13 compression National 69.97 Regional network network stations and a dispatching unit. Gas coming from mld m3 abroad is injected into the network at nine entry Gas injected into the national points, in correspondence with the 6 methane pipeline network interconnection points (including the TAP pipeline which began operating in November 2020) and the three interconnection points for the LNG regasification 3.86 3 terminals. Once it has been imported or regasified, the 66.11 mld m mld m³ Gas from gas is transported to the local distribution networks, the Imported gas national regional network redelivery points or large end users (such production as thermoelectric power stations or manufacturing plants).

Snam awards transportation capacity to shippers who apply. In 2020, 103 connection agreements were entered into In this way, users acquire the right to inject or withdraw a for the creation of new delivery/redelivery points or for quantity of gas not exceeding the daily rate allocated on upgrading existing ones, 19 contracts for the injection of any day of the thermal year.

STORAGE

With 17 bcm of total storage capacity, Snam has the largest capacity in Europe

The storage system makes it possible to compensate for the different requirements for gas supply and consumption: whilst supply has a substantially constant flow throughout the year, gas demand is concentrated mainly in the winter period. Storage also ensures that quantities of strategic gas are available to compensate for any lack of or reduction in non-EU supply or crises in the gas system. Snam carries out its activity through an integrated system of 17 bcm infrastructures, composed of deposits, wells, gas treatment plants, compression Total storage capacity stations and the operational dispatching system. Snam has nine storage concessions located in Lombardy (five), Emilia-Romagna (three) and Abruzzo (one). 4.5 bcm In 2020 Snam took action to promote the replenishment of national storage Strategic storage capacity facilities for the purpose of being able to manage seasonal peaks in demand. The replenishment level at the end of the injection campaign (October 2020) was 99%, in line with the European average. The market oriented approach adopted allowed the Company to increase the 9.3 bcm mix of customers owing a Storage contract (not only shippers serving end users Gas injected into the fields but also traders who maximise revenues from buying and selling gas to the PSV - virtual trading point) as well as attracting major European players.

Through its subsidiary company Stogit, Snam is the largest storage 19.6 bcm operator in Europe by total available capacity. Total storage capacity at the end of 2020, holding strategic storage equal, came Gas moved through the storage to 17 billion cubic metres. A result that attests to Stogit's ability to respond to system both the needs of the national market as well as the contingent dynamics linked to international markets and policies, which can significantly modify demand by increasing the value of business with policies to support the security of supplies. 12.5 bcm Available storage capacity

REGASIFICATION

GNL Italia provides a key contribution to diversification and flexibility of gas supply

Regasification represents the final activity in the liquefied natural gas (LNG) chain. In the exporting country, the natural gas extracted from the fields is liquefied at a temperature of -160°C in order to allow for its transport via tanker to the regasification terminal. Once offloaded from the tanker, the LNG is heated and returned to the gaseous state in order to be injected into the 3 transport network. 17,500 m The regasification service therefore also includes the offloading of the LNG from Maximum daily regasification the tanker, operational storage (i.e. storage for the time needed to vaporize the capacity of the Panigaglia LNG), regasification and injection into the national network. terminal The Panigaglia plant, built in 1971 and owned by GNL Italia, is able to regasify 17,500 m3 of LNG every day. The total amount of gas regasified at the Panigaglia plant in 2020 was 2.52 bcm (+5% vs 2019). The continued increase in 2.52 bcm volumes of activities compared with 2018 (0.91 bcm in 2018, more than doubled Quantity of LNG regasified in in 2020) is mainly due to the greater competitiveness of the cost of LNG 2020 in Panigaglia compared with natural gas, as well as the new regasification capacity llocationa mechanisms through dedicated auctions. The capacity allocation mechanisms based on auctions as well as the new businesses in the SSLNG sector, linked specifically to the possible future uses in 3.5 bcm heavy transportation and maritime transport, will lead to a scenario of further Maximum annual quantity of growth in the consumption of LNG in future years. natural gas that can be released into the transport network In 2020, 60 methane tankers were unloaded (+3 with respect to 2019; +5.3%; +39 unloaded with respect to 2018).
