Our approach


Terna’s core business is electricity transmission and dispatching. These are general interest services that, as in other European countries, are carried out based on a concession by the government, which assigns Terna the role of National Electricity System Operator (TSO). The service provided by Terna is indispensable for the operation of the entire electricity system and thus for supplying electricity to the population.

Given the nature of the service, Terna is not affected by the problems of product responsibility typical of producers of goods or services for end customers, such as the explanatory content of labels, marketing, and advertising.

Even though the end users of the electricity service are not direct customers of Terna, but rather of companies that distribute and sell electricity, the role it performs in the electricity system makes Terna ethically responsible to all of Italian society for the service; the sense of responsibility for a public service is part of the work culture of the Company’s personnel.

Thus Terna strongly feels the responsibility entrusted to it by the government concession and takes on its objectives. In particular, in Italy, the Company undertakes to:

  • provide a service characterized by security, reliability, quality, continuity, and cost-effectiveness, constantly maintaining a balance between electricity demand and supply;
  • keep the transmission system efficient and develop it;
  • comply with the principles of impartiality and neutrality to ensure that all grid users are treated equally.

The responsibility regards both everyday operation and the medium and long term. The grid is Terna’s asset, but it is also an essential infrastructure for the country, and its current management, maintenance, and development must ensure its efficiency and security in the immediate future, as well as for future generations.

Our managerial objectives are therefore first of all connected to complying with regulations and meeting the specific targets established by the industry’s regulatory authority (the AEEG, Electricity and Gas Authority). Particularly important among these are the different measures for service continuity. Terna’s performance in the last few years has always been in line with or exceeded the targets set.

Terna’s role in the Italian electricity system entails specific objectives regarding the security and development of the grid. The security objectives are stated in the Security Plan for the electricity system, in which the investments are planned that are necessary to improve various aspects affecting the security of the electricity system.

The grid development objectives are published in the Development Plan, which is approved every year by the Ministry for Economic Development and sets forth the construction of new electricity lines and stations necessary to ensure the efficiency and cost-effectiveness of the system. Terna selects development projects also according to the condition that overall benefits for the electricity systems are greater than their costs.

The task as operator of the electricity system entails knowledge of confidential data of transmission and dispatching services users, particularly electricity producers. Furthermore, Terna is entrusted by the National Statistics System with the task of compiling 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 follows the best practices for protecting confidential data in order to prevent the information in its possession from being accessible or communicated to third parties that are not entitled to it.
