Gas distribution on the national transportation network

Gas volumes are expressed in standard cubic metres (SCM) with a traditional higher heating value (HHV) of 38.1 MJ/SCM. The basic figure is measured in energy (MJ) and obtained by multiplying the physical cubic metres actually measured by the relative heating value.

The availability of natural gas in Italy in 2013 was 69.50 billion cubic metres, down 4.77 billion cubic metres (-6.4%) compared with 2012.

The quantities of gas issued by the national transportation network decreased by 8.9%, to 69.01 billion cubic metres (75.78 billion cubic metres in 2012), due to reduced imports (-6.08 billion cubic metres; -9.0%) and national production (-0.69 billion cubic metres; -8.4%), partly offset by greater net withdrawals from storage (+2.00 billion cubic metres).

Imports were down by -6.08 billion cubic metres, due mainly to lower volumes injected at the Mazara del Vallo (-8.36 billion cubic metres; -40.2%), Gries Pass (-1.54 billion cubic metres; -17.1%) and Gela (-0.77 billion cubic metres; -11.9%) entry points and to lower volumes injected by the Panigaglia and Cavarzere regasification terminals (-1.07 billion cubic metres and -0.82 billion cubic metres respectively). These factors were partly offset by higher imports from Russia at the Tarvisio entry point (+6.41 billion cubic metres; +26.9%) and by the opening in October of the new Livorno regasification terminal, which injected 0.21 billion cubic metres into the network.
