Italian excellence with a dual purpose. We are among the leading electricity transmission system operators (TSO) in Europe in terms of kilometres of lines managed. 

Our Group plays a dual role: 

  • Terna is the majority owner of the Italian high voltage and very high voltage electricity National Transmission Grid. We operate in a natural monopoly and our public service mission is to secure the transmission and dispatching of electricity throughout the country. 90% of our activities are conducted in the regulated market. Our role is crucial in the operation of the entire system. We work to guarantee the supply of electricity to all, companies and private individuals alike. 
  • Listed on the Stock Exchange since 2004 and with around 70% floating shares, Terna focuses on efficiency, profitability and performance, as our results continually demonstrate. With consolidated expertise gained in the management of the Italian grid, we have invested in market activities, with innovative solutions for the energy market and international projects.

Dispatching, our core business

We are responsible for the transmission and management of electricity flows on the high and very high voltage grid over the whole of Italy. We ensure that there is a constant balance between demand and supply of energy (known as dispatching). Similar to the conductor of an orchestra that "calls" on the different instruments to play and sets the tempo for members of the orchestra, at the National Control Centre, our experts manage the transit of every kWh, from the power stations right through to the major consumption centres. Dispatching is the series of activities that are needed to maintain this balance, 365 days a year and 24/7, and represent the heart of our mission.

In recent years, dispatching has become increasingly complex, as a result of significant development in renewable sources.

A central role in energy transition

Our unique positioning within Italy enables us to adapt our energy systems to our long-term vision, placing us in a strategic position to promote energy transition towards more efficient and eco-compatible production methods. Indeed, the energy sector is currently experiencing deep-seated changes. The continual growth in renewable energy sources and the progressive decommissioning of traditional generation plants means we are facing new challenges, pushing us to develop innovative high-technology solutions and to modernise the grid in order to connect producers with consumers.

Did you know
In Italy, renewable sources covered in 2017 more than one third of the total energy requirement. From as early as 2012, Italy has achieved, maintained and then improved the European Community target of covering above 27% by 2020.


Constant and growing focus on sustainability 

Our dual role – as primary operator responsible for the electricity transmission service in Italy and as a private company ready to take on new development opportunities – is reflected in our focus on sustainability, as underlined by our motto: “Energy is our responsibility. Responsibility is our energy”.

Decarbonisation is already at the door, under Italy’s Energy Strategy electricity production using coal is due to end by 2025. The system will be focused on using renewable sources, becoming more sustainable, and our role in this is crucial in helping Italy through a complete energy transformation. To help meet this challenge our 2018-2022 Strategic Plan closely links the company’s challenges with sustainability.
We manage our services while always remaining mindful of their possible economic, social and environmental repercussions. We strive to create, maintain and consolidate a relationship of mutual trust with our stakeholders, with the intention of aligning strategic development interests with community requirements

In support of the Strategic Plan, the Sustainability Plan that we set out plays a role of limiting ESG (environmental, social and governance) and will help us guarantee in the medium term, a reduction in environmental impact, the availability of the necessary intangible capital - in particular human resources - and observance of the principles of integrity, responsibility and transparency.
