We guarantee a service in the national public’s interest: the transmission and dispatching of electricity in Italy, by
operating the high-voltage grid
planning grid development
constructing the grid.
Unlike other energy sources, electricity is difficult to store. We therefore need to ensure a constant balance between supply and demand.
Economic benefits for the community
Our services contribute to Italy's growth. The development of the electricity grid is especially significant, for the following reasons:
More interconnections with neighbouring connections mean that we can import energy at more competitive prices than that of national production, can have added power reserves available and can guarantee greater competition on the energy market.
- Reducing congestion on the grid improves the utilisation of production sources to meet requirements and makes it possible to use the more competitive plants, creating a positive impact on competition in the generation sector and on end prices.
Our 2019-2023 Strategic Plan sets out investments of around 6.2 billion euros over the next five years. In 2018, we invested 989 million euros in regulated activities.
All our investments in development are subject to preliminary verification. To maximise the cost/benefit ratio, we compare the estimated costs for implementation with the expected benefits on the reduction of the system's overall costs. This ratio should always be above 1.5. Every Euro invested by Terna on average generates a multiple of savings for grid users, which impacts on the end consumer.
Security of the electricity system
The Security Plan, prepared on an annual basis by Terna and approved by the Ministry of Economic Development, is a four-year programme based on initiatives to prevent disruptions on the electricity grid, and if these should occur, to mitigate potential consequences.
The Security Plan takes into account eight different areas, including scheduling, control, regulation and protection, restarting and monitoring of the electricity system, in addition to an area for the secure and optimal management of renewable sources.
In 2018, investment carried out for projects under the Electricity System Security Plan amounted to about 136 million euros, up 108% compared to 2017.
Dialogue with the community
Local communities are fundamental stakeholders for Terna and we aim to create and maintain a solid and collaborative relationship with them. In fact, our 2019-2023 Strategic Plan includes sustainability objectives, linked in particular to the "Stakeholder and Local Community" area. Targets have been defined with the involvement of local communities and by listening to residents, to create shared solutions for infrastructure.
By operating in this manner, we build a collaborative network, and thus develop the grid together. In so doing, our enterprise is more sustainable, focusing not only on the quality of the service we provide, but also on the impact on the environment and natural landscape. During 2018, Terna held a total of 330 meetings with local authorities.

We have direct dialogue with residents of the areas where main development work is taking place. In 2018, Terna held 17 “Terna incontra” events (in Avigliana (TO), Piedmont; Vellezzo Bellini (PV), Lombardy; Auronzo di Cadore (BL), Veneto; Pombino (LI), San Vincenzo (LI) and Suvereto (LI), Tuscany; Codrongianos (SS) and Santa Teresa di Gallura (OT – two meetings), Sardinia; Bisaccia (AV), Lacedonia (AV), Naples and Sorrento (NA), Campania; Alberona (FG), Deliceto (FG) and Troia (FG), Apulia; Cortale (CZ), Calabria.
