The contract includes the design, manufacture and installation of the new high-voltage AC (Alternate Current) power link between Evia and the region of Attika on the mainland.
The project will facilitate the development of wind power projects totaling around 400 MW on Evia, the second largest of the Greek islands, by enabling the power they produce to be exported directly into PPC’s national power transmission grid.
The 150 kV submarine cables will be manufactured in Nexans’ specialized submarine cable facility in Halden, Norway. Installation is planned to be carried out by Nexans’ own cable ship, the “C/S Nexans Skagerrak”. The cables will be buried approximately 1 meter below the seabed. The project is scheduled for completion within 36 months.
The 150 kV link will interconnect the Nea Makri substation on the coast of Attika with the Polypotamos substation on Evia. Nexans will manufacture, supply and install three subsea cable circuits that will take a 21 km route across the Gulf of Evia in waters reaching a maximum depth of 85 metres. Nexans is also supplying the underground power cables (27 km) to provide the land connections at each end of the submarine cables together with associated accessories such as transition joints and outdoor terminations.
