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.
Nexans was awarded a €64 million turnkey contract by Greece’s Public Power Corporation (PPC) to design, manufacture and install the new 150 kV Nea Makri–Polypotamos high‑voltage AC power link across the Gulf of Evia, also known as Attica‑Evia 2. The project involves three three‑core submarine cable circuits on a 21 km route between the Nea Makri substation on the Attica coast and the Polypotamos substation on Evia, providing two operational circuits and one spare to secure power export from wind projects on Evia to the mainland grid. Nexans is also supplying and installing approximately 27 km of single‑core underground power cables in three circuits for the landfall connections on both the Attica and Evia sides, including accessories such as transition joints and outdoor terminations. Manufacture of the submarine cables is carried out at Nexans’ Halden facility in Norway, with installation using the cable‑laying vessel C/S Nexans Skagerrak.
