The gas infrastructure can contribute to the energy transition currently under way and become a lead player.

With its infrastructures, in fact, gas is flexible by nature and therefore able to independently satisfy peaks in demand, something that the electricity system is still unable to do. So, gas plays a fundamental role in making energy production more flexible.

The strategic role

of natural gas distribution infrastructures

How the gas gets to Italy

<p style="text-align: center;">It travels from <strong>remote places</strong> through a series of <strong>infrastructures</strong></p>

<p style="text-align: center;">In Italy alone there are over <strong>32,000 km</strong> of primary transport network and <strong>260,000 km</strong> of local distribution network</p>

The integrated system of infrastructures used to distribute gas is known as a “Distribution System” and is made up of:

Withdrawal stations

Withdrawal stations are the systems that connect local networks to the national pipeline network. 

These points are used for delivery, filtration, pre-heating prior to pressure reduction, pressure adjustment, metering and gas odourisation.

Currently Italgas Group has several hundred withdrawal stations, all with advanced remote control and remote reading systems. The remote control permits maximum timeliness for an intervention in the event of a fault, while remote metering allows the continuous detection of a number of parameters related to the management of gas flows, therefore detecting the amount of incoming gas in the networks.

Distribution networks and pressure reduction plants

The sections of the distribution network are classified according to their operating pressure:

  • the mains (higher than 5 bar);
  • medium pressure (higher than 0.04 bar up to 5 bar);
  • low pressure (up to 0.04 bar).

Pressure reduction plants are devices placed along the distribution network: these are devices designed to bring the gas pressure to the right level in relation to the type of use.

Many thousands of these plants are in operation on our networks, divided into final reduction units, industrial reduction units and utility units.

Redelivery points (pdrs) And meters

The redelivery points are located between the gas distribution system and the domestic system under the responsibility of the end customer.

Gas meters are installed in the redelivery points. We purchase the meters solely from specialist industries, world leaders in this sector.
