The completion of the laying of the eastern branch of the Tyrrhenian Link, Terna’s direct current power line, marks the conclusion of the marine works between Campania and Sicily. The company announced this, explaining that the connection was created by Prysmian, which in 2021 was awarded the framework contract for the design, supply, installation and testing of over 1,500 km of cables for Terna’s main connections. In May 2025, on board Prysmian’s Leonardo da Vinci ship, the first cable of the eastern branch of the Tyrrhenian Link was installed, 490 km long, from Fiumetorto (Termini Imerese, PA) to Torre Tuscia Magazzeno (Battipaglia, SA). The second power line, of the same length, was laid with the ship Monna Lisa from Campania to Sicily, officially completing the route. Overall, 150 days of naval activity were spent on the construction of the eastern branch, with advanced technologies and continuous monitoring of the route. Construction is also underway on the land front at the sites that will host the conversion stations in Eboli (SA) and Termini Imerese (PA). In Campania, the infrastructure will be connected to the Torre Tuscia Magazzeno landing place through an underground power line of approximately 15 km, designed to minimize environmental and landscape impact. Similarly, in Sicily, the station will be connected to the Fiumetorto landing place with an underground cable route of approximately 10 km.
The Tyrrhenian Link also includes the western branch between Sicily and Sardinia: the laying phase of the first of the two submarine links ended in January this year, explains Terna. With a total investment of approximately 3.7 billion euros, the work involves two 500 kV direct current sections, extending for approximately two thousand kilometers of underwater route. The eastern branch is also one of three Terna projects included in the European REPowerEU programme, confirming the strategic value of the work also at community level, with funding of 500 million euros. Thanks to its high transmission capacity, the Tyrrhenian Link will contribute to achieving the decarbonisation objectives defined by the National Integrated Energy and Climate Plan (PNIEC). The infrastructure will strengthen the electricity interconnection between Campania, Sicily and Sardinia, favoring an increase in exchange capacity, improving the adequacy and flexibility of the network and guaranteeing greater security, reliability and resilience to the national and European electricity system.
