Terna’s main business line is the transmission of electricity on high-voltage lines connecting power stations to distribution networks. This service is licensed by the government. In Italy, where Terna is the main owner of the high-voltage National Transmissioni Grid, with over 56,000 kilometres of lines, the Company also performs the role of operator of the electricity system. The service is indispensable for the functioning of the entire system and supplying electricity to all Italians.

Given the nature of the service, Terna is not affected by issues of product responsibility typical of companies that produce goods and have a relationship with end consumers, such as label content, marketing, and commercial communication.

Even though the end users of the electric service are not Terna’s direct customers, the essential role the Company performs in the electricity system makes it ethically responsible for the service to all Italians. A sense of responsibility for a public utility service is part of the working culture of Terna’s employees.

Therefore Terna strongly feels the responsibility entrusted to it by the government licence and makes the latter’s objectives its own. In particular, with regard to Italy it undertakes to:

  • provide a service that is secure, reliable, continuous, and cost-effective;
  • maintain the transmission system efficient and develop it;
  • observe the principles of impartiality and neutrality to ensure equal treatment for all grid users.

Terna’s responsibility regards everyday operations, as well as the medium and long run. The transmission grid is owned by Terna, but it is also essential infrastructure for Italy, and its management, maintenance, and development must take into account the necessity of ensuring its efficiency not only today, but also for future generations.

The Company’s objectives are, therefore, first of all connected with complying with the regulations and targets specified by the industry’s regulatory authority, the Authority for Electricity and Gas (AEEG). Particularly important among the latter are various measures of service continuity. Terna’s performance in the last few years has always been in line with or better than the targets set.

Terna’s role in the Italian electric system entails specific objectives regarding the security and development of the grid. The security objectives are included in the Defence-System Improvement Plan, which specifies investment for work on various aspects that affect maintenance and, if need be, the restoration of the security conditions of the electric system.

Electric pylonThe objectives of grid development translate into work that is included in the Developmenti Plan, which must be approved every year by the Ministry for Economic Development. Among other things, Terna chooses the work to be done according to the criterion that the economic benefits must exceed the costs for the electric system as a whole.

The role of electricity system operator entails the possession of confidential data of the users of the transmission and dispatching services, in particular electricity producers. Furthermore, the National Statistics System assigns Terna the task of processing the statistics of the Italian electricity industry, for which information is collected from the companies concerned. For these data and those it processes to manage its economic relations with grid users, Terna employs the best practices for protecting confidential data in order to prevent information in its possession from being accessible or communicated to third parties that are not so entitled.
