Brussels, 26 October 2023


Cenergy Holdings announces that Hellenic Cables, its cables segment, has signed a contract with Seaway7 for the East Anglia THREE offshore windfarm which is being developed by ScottishPower Renewables.  This collaboration underscores Hellenic Cables' commitment to delivering high-quality cable solutions for renewable energy projects and reaffirms its position as a key player in the industry.

East Anglia THREE offshore windfarm is located approximately 69km NE off the Suffolk coast and will have installed power capacity of 1,400MW, producing enough green electricity to power the equivalent of more than 1 million homes.  Once operational in 2026, it will be the second largest offshore windfarm in the world.

Under the contract, Hellenic Cables will be responsible for the engineering, manufacturing, testing and supply of approximately 275km of 66kV three-core Inter Array submarine cables and the supply of the associated accessories.  Production will get underway in 2024.
The production of the submarine cables will take place at Hellenic Cables' vertically integrated state-of-the-art manufacturing facility in Corinth, Greece, where a skilled team of experts will utilize cutting-edge technology and adhere to the highest industry standards to deliver top-quality products.

Mr. Norris, Project Director for Seaway7 said: “We are pleased to have awarded the contract to Hellenic cables for the East Anglia THREE project. We look forward to working with them once again, building on our long-established relationship, following the success of our most recent collaboration on another large offshore windfarm within the United Kingdom”.
