Energy transformation, a challenge for the grid. The energy sector is transforming, and our Group is taking a leading role in steering change in Italy. Positioned at the centre of the electricity system, and having anticipated these chances, Terna is now tasked with promoting and guiding energy transformation.

In the electricity sector, we support the continual growth in renewable sources, and progressive evolution in the larger generation plants. The development of the grid is crucial in this process of moving towards new ways of producing and consuming, meeting the needs of lifestyles that continue to evolve over time.

In line with European Union directives, projects aimed at decarbonising energy production are picking up pace: Italy’s Energy Strategy adopted in November 2017 aims for the decarbonisation of electricity in the country by 2025. At the same time we can constantly looking for increased market efficiency and procurement security.

With this in mind, the development of the electricity grid in Italy is the top priority in our 2019-2023 Strategic Plan, with planned investments of 6.2 billion euros. This is Terna’s highest economic commitment ever, up almost 20% compared to our previous plan: an unprecedented challenge due to its size and complexity.

More specifically, we will dedicate: 

•Over 3 billion euros to strengthen connections between different market zones in Italy, increase international interconnections and modernise the networks in the main Italian cities (see Key Investment for Italy, below).
•Approximately 1 billion euros for our Defence Plan, aimed at improving security and stability in the system and further developing fibre optics.
•Approximately 2 billion euros for renewal projects to improve efficiency and quality of service, and for the digitalisation of the electricity grid

70% of new investments will be sustainable since we intend to improve congestion and improve the quality of service as well as the environmental and visual impact. In particular, over 70% of the new power lines that will come into service during the plan will be "invisible" because they are use underground or submarine cables.

Key investiments for Italy 

Strengthening internal connections. Among the main projects to increase exchange capacity among the different zones of the Italian electricity market, we highlight the "Colunga-Calenzano" power lines (between Tuscany and Emilia-Romagna) and "Gissi-Foggia" (between Abruzzo and Puglia).

International interconnections. Projects aimed at placing Italy in the middle of the northern-continental, Balkan and European-Mediterranean system continue in order to facilitate the progressive integration of the continental markets. Among the primary infrastructure projects underway, there are the interconnections with Montenegro and France ( (which are expected to begin operating in 2019 and 2020 respectively)) and the start of works on the new SACOI 3 project (to connect Sardinia, Corsica and mainland Italy).

Rationalisation of electricity grids in metropolitan areas. The plan covers the cities of Milan, Rome, Naples and Palermo in particular and will involve, first and foremost, the replacement of old infrastructures with new, sustainable and technological cables.
