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
It travels from remote places through a series of infrastructures
The European natural gas network has over 2 million km of pipelines and 100 million delivery points
In Italy alone there are over 32,000 km of primary transport network and 260,000 km of local distribution network
The integrated system of infrastructures used to distribute gas is known as a “Distribution System” and is made up of:
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.
