Brussels, 9 July 2020

Cenergy Holdings announces that its subsidiary Hellenic Cables has been awarded the supply of 66kV inter-array cables and accessories for the Seagreen offshore wind farm in the UK.



Hellenic Cables, leading provider of submarine cable solutions, has been awarded a contract by Seaway 7, the Renewables business unit of Subsea 7, to supply 66kV inter-array cables and accessories for the Seagreen offshore wind farm.

The Seagreen offshore windfarm project is a 1,075MW project, located 27km off the Angus Coast in the Firth of Forth, off the coast of Scotland and will be developed and operated by Seagreen Wind Energy Limited.  Once constructed, the windfarm will be the largest in Scotland and is forecast to provide low carbon energy for around one million homes.

SSE Renewables recently announced the final investment decision (FID) for the 1,075MW Seagreen 1 offshore wind development, alongside an agreement to sell a 51% stake in Seagreen 1 to Total SA.

Under the contract, Hellenic Cables will design, manufacture, test and supply approx. 320 km of 66kV XLPE-insulated inter-array cables and associated accessories.  The cables will be produced in Corinth, Greece, at Hellenic Cables’ vertically integrated, state-of-the-art submarine cables plant.  Delivery is planned by early 2022. 

Seaway 7 was awarded by Seagreen Wind Energy Limited a contract for engineering, procurement, construction and installation (EPCI) of the foundations and inter-array cables for the Seagreen 1 offshore wind farm.
