Italian firm wins contract for Tunisia power link

29 September 2025

Italy’s Prysmian Group has won a contract to build a submarine electricity interconnection between Italy and Tunisia as part of the Elmed Project.

The tender was launched by Italian transmission system operator Terna and Tunisian grid operator Steg.

Prysmian said the deal initially provides for a “preliminary activation phase” and is subject to certain conditions.

Once met, the contract value could reach about €460m ($540m).

The connecting cable will run between the Partanna substation in Sicily and the Mlaabi substation on Tunisia’s Cap Bon peninsula. It will cross the Strait of Sicily at depths of up to 800 metres. Installation will be carried out using the cable‑laying vessel Monna Lisa.

Prysmian, listed on the Italian stock exchange, has previously delivered several subsea cable projects for Terna, including the Tyrrhenian Link, for which it set a world record by installing a high‑voltage direct current (HVDC) cable at a depth of 2,150 metres during sea trials.

Other projects include the Adriatic Link between Marche and Abruzzo and the SA.CO.I.3 HVDC project linking Sardinia, Corsica and Italy.

Backed by the EU, the Elmed Project is a scheme to build a 600MW HVDC submarine interconnector between Sicily and Tunisia, with completion targeted for 2028. The project is the first direct electricity link between Italy and North Africa. 

The only existing subsea electricity interconnections between North Africa and Europe are the two Spain–Morocco links across the Strait of Gibraltar, commissioned in 1997 and 2006.
