Infrastructure and storage service

Shrough its subsidiary company Stogit, Snam is the largest storage operator in Italy, with a 97% share of total available storage capacity, and one of the largest in Europe. It carries out its activity through an integrated system of infrastructures, composed of deposits, gas treatment plants, compression stations and dispatching operations. 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, the demand for gas 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. The storage business makes use of integrated infrastructure comprising deposits, wells, gas treatment plants, compression stations and the operational dispatching system. Snam has nine storage concessions located in Lombardy (five), Emilia-Romagna (three) and Abruzzo (one).The new Bordolano site has been operational since 2015.

Thanks to the investments made into developing new fields and strengthen existing ones, the total storage capacity at the end of 2017, including strategic storage, reached 16.7 billion cubic metres (+ 0.2 billion cubic metres compared to 2016).

In 2017, 19.92 billion cubic metres of natural gas was moved through the storage system, (which was in line with volumes moved in 2016: -0.4%).

In October 2017, Stogit reached a modulation storage volume at the storage system of 11,829 million standard cubic metres of gas, achieving a new historical peak. A result that attests to Stogit’s ability to respond to 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.
