The Terna Business Model

Terna is Europe's largest independent grid operator for the transmission of electricity (Transmission System Operator - TSO) and is sixth worldwide in terms of kilometres of lines managed.

The Terna Group owns the Italian National Transmission Grid (NTG) with more than 57,400 kilometres of high voltage lines (more than 63,400 km of three-phase power lines), 468 transformation stations and 22 interconnection lines with foreign countries.

In Italy, Terna acts as TSO under a government concession. It is responsible for transmitting and dispatching electricity along the high-voltage and very-high-voltage grid throughout the whole of Italy. Terna is also responsible for planning, constructing and maintaining the grid.

Terna's mission is:

  • to manage electricity transmission in Italy, guaranteeing its security, quality and affordability over time;
  • to ensure equal conditions of access to all grid users;
  • to develop market activities and new business opportunities with the experience and technical skills gained in the management of complex systems;
  • to create value for the shareholders with a strong commitment to professional best practices and with a responsible approach to the community, respecting the environment in which it operates.

The Italian electrical system chain consists of four segments: the production, transmission, distribution and sale of electricity.

In this chain, Terna is in charge of managing the electrical system through operating the high voltage grid, maintaining the infrastructure and developing the grid (planning and construction).
