Wind Energy – Inter-array Cables Hornsea 3
Hellenic Cables signed a contract with Ørsted for the supply of inter-array cables for the Hornsea 3 offshore wind farm.
Under the contract, Hellenic Cables will be responsible for the design, manufacturing, supply, termination and testing of the inter–array cables that will connect the wind turbines and the offshore converter station.
The scope of supply involves approximately 262 km of 66kV inter-array cables with XLPE insulation, comprising approximately 50% of the overall wind farm requirements. Manufacturing will begin in Q4 2025 in Hellenic Cables’ state-of-the-art submarine cable plant in Corinth, Greece.
With a capacity of around 2,85 gigawatts (GW), Hornsea 3 will be capable of producing enough low-cost, clean, renewable electricity to power over 3 million UK homes – making a significant contribution to the UK Government’s ambition of having 50 GW offshore wind in operation by 2030.
Hornsea 3 will be located 160 km from the Yorkshire coast. When fully online, Ørsted’s Hornsea zone – comprising Hornsea 1, 2 and 3 – will have a total capacity of in excess of 5 GW. This will be the world’s largest offshore wind zone, producing enough low-cost, clean, renewable electricity to power more than 5 million UK homes.
