Network Plan Listed

On 14 March 2025, Terna S.p.A. presented its 2025-2034 National Electricity Grid Development Plan, in which the Ionian-Tyrrhenian Backbone (project code 563-P/HG-4) is listed as Corridor 4 of the Hypergrid programme. The 2025 NDP refines the scope to three HVDC sections: an undersea HVDC line between the planned Latina converter station and an overhead-cable transition station near Montecorvino; a DC modernisation reconstructing the existing Rossano-Laino (380 kV) and Laino-Tusciano (220 kV) AC corridors at up to plus/minus 525 kV DC between Montecorvino and a new converter station near Rossano; and an undersea HVDC line between Rossano and a new converter station near Priolo in Sicily. The plan places the project in the post-2034 grid architecture envelope, with completion targeted by 2040 alongside the Sardinian backbone, the 380 kV Aliano-Montecorvino power line and complete-project GRITA2. This shifts the schedule from the 2035 commissioning year shown in the 2023 NDP and reaffirmed by the ENTSO-E TYNDP 2024 Continental South East Regional Investment Plan. The plan was presented by Terna Managing Director Giuseppina Di Foggia in the presence of MASE Minister Gilberto Pichetto Fratin and ARERA Chairman Stefano Besseghini, and forms part of an overall 2025-2034 investment programme of more than EUR 23 billion (with up to EUR 40 billion beyond the ten-year horizon).
