Prysmian Group won a contract worth about $127 million by Independent Power Transmission Operator, the transmission system operator of the Greek electricity system, for the interconnection between the island of Syros (Cyclades) and the mainland power transmission System in Lavrion, Greece.
The project involves the design, supply and installation of a turnkey high voltage alternating current (HVAC) cable system designed to transmit a power of 200 MVA and consisting of 150 kV extruded cables and associated fiber optic cable system along a total route of more than 110 km (108 km submarine and 2 km land) for the interconnection between the two landfalls that will enable integration of Syros into the Greek network system and future expansion to the other Cyclades Islands (Paros, Mykonos, Tinos).
The submarine cables for the Lavrion-Syros link will be manufactured in the Arco Felice plant (Naples), the Group’s center of technological and manufacturing excellence. Production of both submarine and land cables will be during 2015. Cable installation and protection will be completed within 22 months in 2016.
Prysmian has a long-standing track record in the development of submarine interconnection milestone projects in the entire Mediterranean region, such as Italy-Greece, Sardinia-Italian Peninsula (SA.PE.I.), two interconnections between Spain and Morocco, two projects in the Balearic Islands (Spanish Mainland to Majorca and Ibiza to Majorca) and the Dardanelles in Turkey.
Prysmian is also a founding member of the industrial partnership Medgrid, launched to study the feasibility of a high-voltage direct current interconnection project to transmit electricity from solar or wind power plants to load centers on either rim of the Mediterranean.
