Important news about Tyrrhenian Link, the infrastructure that will connect Sicily with Sardinia and the Italian peninsula. In fact, the work involves the construction of four high voltage direct current (HVDC) submarine cables. The eastern section, which will connect Sicily and Campania, is approximately 480 km long, while the western section, between Sicily and Sardinia, is 470 km long. In total it reaches 950 kilometers in length and 1000 MW of power.
Well, Terna announced today, Tuesday 30 November, the signing of two framework contracts with Prysmian and Nexans (in association with Roda and Mive) relating to this strategic infrastructure for the country. The agreements concern, in particular, the supply and laying of submarine and underground cables and have a maximum value of 1,7 billion euros for Prysmian and 664 million euros for Nexans.
Depending on what is expected, Prysmian will install one to three connections. Nexans, on the other hand, will create a link with similar characteristics.
The new interconnection, explains Terna, "is a cutting-edge project and, in addition to being the longest electricity infrastructure ever built in Italy, will reach the world depth record of laying submarine cables, reaching approximately 2.000 meters below sea level". Marine laying will be carried out by Prysmian and Nexans, while Italian companies from Terna's qualified sectors will be involved for laying on land.
The company led by Stefano Donnarumma will invest in the Tyrrhenian Link over the next few years 3,7 billion euros, involving around 250 companies in the construction of the work.
Finally, we recall that, at the beginning of November, the Minister of Ecological Transition, Roberto Cingolani, signed the formal initiation of the authorization procedure of the East Branch. The work in its entirety will be fully operational in 2028, but the first of the two cables of the East Branch will be operational as early as the end of 2025, Terna announced.
