An unique integrated Dispatching center: the Dispatching Centre provides to the monitoring and remote controlling of the transport network operations, receiving data from around 3,800 plants located along the transport network, with more than 1,600 of them controlled remotely. In addition to that, it remotely controls 9 storage plants

Ensuring service quality, reliability and continuity in the management of safe energy supply for Italy, is an essential requirement in order for Snam to be able to operate.
Group companies have maintained a high level of service quality and engage with clients on an annual basis through customer satisfaction surveys.
A list of indicators was identified to monitor the quality of service provided, automatically compensating customers in the event of non-compliance with service quality standards.
Snam’s performance in 2021 remained strong with regard to these indicators, for example reaching 100% compliance with time frame for issue of connection offer in transmission, 100% compliance with time frames for providing services subject to specific commercial quality standards in storage and reaching 100% compliance with the maximum period of interruption/reduction in capacity at the terminal due to maintenance works in regasification.
With a view to ensuring continuous improvement, the monitoring of service quality directly involves customers through annual customer satisfaction surveys.
Service continuity is of key importance for Snam which frequently checks its infrastructures.
To ensure service continuity, the company’s facilities and pipelines are subjected to regular checks and maintenance operations. With regard to gas transmission, for example, special attention is paid to the transmission route, which is inspected regularly with motor vehicles, helicopters and on foot, in order to detect potentially dangerous situations caused, for example, by work performed by third parties in the vicinity of the pipeline. Similarly, any movements that could cause landslides at specific points along the route are kept under control. The integrity of pipelines is also checked by running devices known as “intelligent pigs” through them, enabling possible faults to be detected.
Technological innovations in this field are constantly evolving and Snam is committed to researching and developing new opportunities, with a view to constantly improving its ability to observe the infrastructure and prevent and/or intercept potential dangerous situations for network security. The company has recently equipped itself with drones and an organisational structure based on an aviation model, as well as with satellite tracking technologies. In this context, project work has been completed on a pilot route of approximately 1,400 km and field verification of the evidence produced is underway, with initial results being very satisfactory.
In addition, the implementation of the Leak Detection and Repair (LDAR) project, developed in-house, continued in 2021, enabling inspection and field surveys to be carried out in order to prevent, detect and resolve any methane leaks from pipelines.

The 13 gas compression stations situated along the more than 32,500 km of pipeline network are controlled directly by the recently renovated dispatching unit at San Donato Milanese, which is responsible for ensuring that pressure levels are sufficient to meet demand. The network is also monitored using ongoing remote readings of cathodic protection meters as well as manual readings.
In the case of events that could lead to the interruption or unavailability of business processes, Snam has adopted a Business Continuity Management policy to manage the Business Continuity Management process and ensure an appropriate reaction to emergency situations, which is centralised at Group level and applies directly to all Group subsidiaries.
In accordance with the safety management system policy and guidelines, Snam has also established a Crisis Management Model, consisting of all the rules and methods for declaring and managing events which could lead to a crisis.
The Dispatching Centre
The Dispatching Centre provides to the monitoring and remote controlling of the transport network operations, receiving data from around 3,800 plants located along the transport network, with more than 1,600 of them controlled remotely.
Through the use of a specific software application, the data collected, also on the basis of historical consumption and weather forecasts, makes it possible to formulate short-term forecasts for the gas demand and to simulate and optimise the gas flows in the network, guaranteeing the best arrangement for the compression stations to thereby reduce their consumption and containing in this way the emission levels.
The network operations and the physical balancing of the system are constantly guaranteed by an operations room staffed 24/7, which, based on the programming defined by customers and in coordination with Italian and foreign infrastructure operators connected to the transportation network, ensures the correct movement of the gas from the injection points to the withdrawal points.
In addition to that, the dispatching Centre remotely controls 9 storage plants, planning and carrying out the operations for the surface treatment plants, shaft and compression area, guaranteeing a secure execution in ordinary, irregular or emergency operating conditions.
During the Covid-19 emergency, Dispatching, which represents the nerve center of the national gas transport network and which cannot stop under any circumstances, has worked in isolation, constituting an example of resilience and becoming an international best practice also adopted by National Grid , ALNG and Transitgas.
