Hellenic Cables, the cables business of Cenergy Holdings, has been awarded a contract by DEME to supply the inter-array cable system for the BC-Wind offshore wind project in Poland. The scope puts Hellenic Cables at the center of the wind farm’s internal power collection network, a package that is often decisive for commissioning timelines because it connects each turbine string to the offshore electrical system and ultimately governs how reliably generation can be consolidated.

 

Project Location and Developer Structure

 

BC-Wind is being developed by Ocean Winds, the offshore wind developer jointly owned by EDP Renewables and ENGIE. The project is planned around 23 kilometres off Poland’s Baltic Sea coast and is designed for 390 MW across 26 turbines. Once operational, the developer expects the wind farm to supply electricity equivalent to the annual consumption of around half a million households, positioning it as a material contribution to Poland’s Baltic offshore pipeline.

 

Technical Design and Cable System Parameters

 

Under the agreement, Hellenic Cables will handle design, engineering, manufacturing, testing, and supply for roughly 70 kilometres of 66 kV inter-array submarine cables, including spares, alongside the associated accessories. Inter-array systems at this voltage level are built around demanding performance requirements, because they need to balance electrical losses, mechanical protection, and installation constraints while operating in a harsh marine environment where faults are costly and repairs are operationally disruptive.

Manufacturing Footprint and Schedule Signal

 

The cables will be produced at Hellenic Cables’ submarine cable manufacturing facility in Corinth, Greece, with completion of production expected by the end of 2027. That schedule indicates a long-lead procurement approach typical for offshore wind, where manufacturing slots, testing windows, and logistics planning can become binding constraints well before offshore installation begins.

 

Relationship Continuity and Interface Reduction

 

The inter-array award follows an earlier export cable EPCI agreement for BC-Wind signed by Hellenic Cables in consortium with DEME and contracted by Ocean Winds. With both export and inter-array elements tied to the same industrial pairing, the project reduces the number of interfaces across cable supply and delivery, which can help limit coordination risk during installation, testing, and handover.

 

Execution Outlook for the Baltic Supply Chain

 

Statements from DEME, Hellenic Cables, and Ocean Winds frame the award as an extension of an existing working relationship across multiple offshore wind developments. For the Baltic region, the contract also reflects a broader market reality where cable manufacturing capacity and proven installation partners have become central to delivery credibility, especially as Poland accelerates construction-phase activity and seeks schedule certainty across multiple projects competing for the same European supply chain.
