Brussels, 30 September 2020


Cenergy Holdings announces that its subsidiary Hellenic Cables has been awarded the supply of 66kV array cables and accessories to the world’s largest Offshore Wind Farm.

Hellenic Cables, leading provider of submarine cable solutions, has been awarded its biggest to-date contract for inter-array cables by DEME Offshore, the renewables business unit of DEME Group, for the supply of approx. 650 km 66 kV inter-array cables and accessories to Dogger Bank Offshore Wind Farms phases A & B in the UK.



Dogger Bank Wind Farm is located more than 130 km off the North East coast of England and is currently being developed in three 1.2 GW phases by joint venture partners SSE Renewables and Equinor.  Dogger Bank will be the world’s largest offshore wind farm, when complete, and will generate enough energy to power over 4.5 million homes every year – around 5% of the UK’s electricity needs.

Under the contract, Hellenic Cables will design, manufacture, test and supply approx. 650 km of 66 kV XLPE-insulated inter-array cables and associated accessories.  The cables will be produced at Hellenic Cables’ vertically integrated, state-of-the-art submarine cables plant in Corinth, Greece.  Production of the cables for Dogger Bank A & B will commence in 2021 and delivery will be a phased roll out in line with the project execution program.

DEME Offshore was awarded by Joint venture partners SSE Renewables and Equinor, a contract for engineering, procurement, construction and installation (EPCI) of the subsea inter-array cables for the combined first two phases of the offshore wind farm.  This contract is subject to both joint venture partners reaching financial close on Dogger Bank A and B, expected in late 2020.
