We pursue non-regulated international initiatives abroad with a view of diversifying our business. We focus on countries with stable political and regulatory frameworks, using our knowledge and skills to improve their electricity infrastructure.

We work in collaboration with energy operators with a consolidated presence abroad. This not only presents a business opportunity for us, but also allows us to extend our knowledge and gain new skills, whilst also providing an attractive risk/return ratio for the Group.

We provide the following services abroad:

  • Concessions: the acquisition and management of transmission systems abroad by taking part in international concession tenders;
  • EPC: the creation of Engineering, Procurement & Construction Projects for high-voltage transmission assets. We will develop this on behalf of third parties;
  • Technical assistance: the supply of engineering and regulatory consultancy services for third parties operating in the electricity sector. We also participate in these via public tenders;
  • BOOT (Build, Own, Operate, Transfer) and BOT (Build, Own, Transfer): the BOOT model comprises the design, construction and operation of transmission infrastructures and their ownership for a defined period of time. The BOT model exclusively design and construction and the transfer of ownership of the infrastructure.
Our recent international projects
In September 2016, Terna won a Uruguayan tender for the creation of three electrical infrastructures. Find out more about this tender in our press release. In 2017 in Brazil, an agreement was signed with Planova, a Brazilian construction company, aimed at the acquisition of two concessions to operate a total of around 500 km of electricity infrastructure in the South American country. Find out more about this tender by reading our press release.Still in 2017 Terna formalised the contract for the construction of 132 km of 138 kV power line in central Peru, connecting the electricity substations of Aguaytìa and Pucallpa. Find out more about this tender by reading our press release.

Interconnector Projects

The development of a single electricity market by expanding the interconnection infrastructure with other countries by subjects other than grid operators became EU law in 2006. Italy formalized these guidelines into national Italian Law 99/2009, and assigned Terna the task of carrying out public tenders to select the subjects willing to finance specific interconnections, in exchange for the benefits deriving from the allocation of transfer capacity for a pre-established number of years.

Five interconnectors are planned in total with the borders of France, Switzerland, Montenegro, Austria and Slovenia, two of which are at an advanced construction stage (Italy-France and Italy-Montenegro).

Italy-France Interconnector. The new “Italy-France” direct current interconnector, between the substations of Piossasco and Grande Ile, will make the cross-border interconnection with France the most important for Italy, increasing cross-border interconnection capacity by 1200 MW (of which 350 MW available in third-party access exemption to the selected undertakings), which will rise from the current level of approximately 3 GW to more than 4 GW.

Italy-Montenegro Interconnector. The project aims to create a total of approximately 1200 MW of new cross-border interconnection capacity between Italy and Montenegro split into two modules of 600 MW each. A portion of the 600 MW provided by the first module will be available in third-party access exemption to the selected undertakings (private investors).

Italy-Austria Interconnector. The Italy-Austria Interconnector (Reschenpass project), currently awaiting the necessary consents, involves the creation of a new 220 kV alternating current interconnector between the substations of Nauders (AT) and Glorenza (IT). The connection will consist of approximately 26 km of underground cable and will require the related adjustments on the domestic grid. The project will enable an increase in cross-border interconnection capacity between Italy and Austria of approximately 300 MW, which will practically double the capacity currently available.

Italy-Switzerland Interconnector. The project involves the development of new transmission lines between Italy and Switzerland, partly in alternating current and partly in direct current. As far as the first type is concerned, a 380 kV connection will be built between Airolo All’Acqua (CH) and the new substation of Pallanzeno (IT). This will be connected to a system in direct current up to the 380 kV Baggio substation, making a total distance of more than 160 km. The project, which is currently awaiting the necessary consents on the Italian side, will significantly increase interconnection capacity between Italy and Switzerland, raising it from the existing 4 GW to approximately 5 GW.

Italy-Slovenia Interconnector. The creation of a direct current line is planned, partly in undersea cable, between the substations of Salgareda (IT) and Divaca/Bericevo (SL), together with work on upgrading the domestic grids in Italy and in Slovenia. The project is currently awaiting the necessary consents on the Italian side. The expected increase in cross-border capacity by approximately 1 GW will raise the interconnection capacity to more than double the existing level.
