Terna is an independent grid operator and one of the key players in Europe, thanks to its 72.000 km of lines managed and with more than 3.700 experts who are tasked every day with ensuring the safety of Italy’s electricity system.

The Group’s company structure comprises the holding company, Terna S.p.A., and its two operating subsidiaries: Terna Rete Italia and Terna Plus, each with its own Board of Directors.

This leading role makes Terna responsible for service towards the entire national community. The service which Terna provides in Italy is crucial to the operation of the entire electricity system and for guaranteeing the supply of electricity to all, companies and private individuals alike.

In playing such a leading role, Terna has responsibility for supplying the entire country’s electricity needs, not directly but via those companies that distribute and sell electricity to end-consumers. The sense of responsibility in providing a service of such wide-ranging importance is integral to Terna’s company culture.

Terna Group is a leading Italian corporation. The Company is responsible for the planning, development and maintenance of the grid, combining competence, technologies and innovation in keeping with international best practices.

Through its subsidiary, Terna Plus, the company is responsible for developing new businesses, both in Italy and abroad. It seeks to exploit business opportunities stemming from technology gaps and from trends peculiar to the energy sector, such as: growth in renewable energy sources, Smart Grid development and energy efficiency. As part of the implementation of Non Traditional Activities, Terna Group has signed the closing for the acquisition, by Terna Plus S.r.l., of the entire capital of Tamini Trasformatori S.r.l. (Tamini) and of its subsidiaries Tamini Group, a company that produces and sells industrial electrical and power transformers.

Specifically, in Italy, through Terna Rete Italia, it is engaged in:

  • providing a service that ensures safety, reliability, quality, continuity and cost-effectiveness maintaining a continuous balance between electricity supply and demand;
  • maintaining efficiency and developing the transmission system;
  • respecting the principles of fairness and neutrality to ensure equal treatment of all grid users.

Its responsibility covers both day-to-day operations and those in the medium to long period: the electricity transmission grid is a Terna asset as well as a vital infrastructure of the country. Its management, maintenance and development must be geared to ensure efficiency and safety both today and in the future.
