Brussels, 21 April 2021


Cenergy Holdings SA announces that Hellenic Cables, its cables segment, in joint venture with Asso.subsea Ltd, has been selected by Terna Energy SA, following an international tender, for the design, manufacturing, supply and installation of the 150 kV submarine cable system which will connect the under-construction 330 MW Kafireas II Wind Farm to Greece’s mainland grid.



Kafireas II Wind Farm, located in the southern-most part of Evia island, will be connected to the national Power Transmission System at IPTO’s 150 kV Lavrion substation.  The Interconnection Cable System includes approx. 70 km of 150 kV three-core composite submarine cables as well as 11 km of 150 kV single-core underground onshore cables, along with all accessories, joints, terminations and fittings, necessary for the completion of the system.
