On 24 June 2024, Terna issued the non-technical summary for the Hypergrid HVDC Milan–Montalto connection, defining preferred and alternative feasibility corridors for the entire route, including the subsea and onshore cable sections and the overhead HVDC line. The document specifies a bipolar ±525 kV, 2,000 MW link with approximately 250–300 km of submarine cable between Montalto di Castro (Lazio) and the Avenza area near Carrara (Tuscany), around 10 km of terrestrial HVDC cable on the Tuscany side and about 2 km on the Lazio side, as well as roughly 170 km of overhead HVDC line from Avenza to the new Sud Milano converter station, largely following and replacing existing HVAC lines. These route corridors, landfall options and converter station locations across Lazio, Tuscany, Liguria, Emilia-Romagna and Lombardy represent completion of a key phase of cable and line route engineering for the Milan–Montalto subsea link.
