Prysmian awarded project for submarine interconnection

Prysmian Group, leader in the energy and telecom cable systems industry, has been awarded a new contract worth approximately Euro 21 million by IPTO (Independent Power Transmission Operator), the transmission system operator of the Greek electricity system, for two interconnections between the Cyclades islands (Evia, Andros and Tinos), Greece. The project involves the design, supply and installation, as well as the related land civil work of two turnkey high-voltage alternating current (HVAC) cable systems designed to transmit a power of 200 MVA and consisting of 150 kV three-core cables with XLPE insulation and double wire armouring and associated fiber optic cable system along a total route of over 18 km (16.5 km submarine and 2 km land) for the interconnection between the four landfalls. 

The submarine cable system will increase and ensure robust, reliable and sustainable power transmission system between the Cyclades islands. The maximum water depth expected will be in the range of 550 m in the link between the islands Evia and Andros. The submarine cables for the link will be manufactured in the Arco Felice plant (Naples), the group’s centre of technological and manufacturing excellence, while land cables will be produced in Pignataro, Naples. Marine cable laying activities will be performed by the group’s Giulio Verne cable-laying vessel. Production of both submarine and land cables will be carried out during 2018-2019. Delivery and commissioning is scheduled for Q3 2019. This new project confirms Prysmian’s role and commitment in developing the Mediterranean region’s power grids and particularly in deep water cable installation.
