Hellenic Cables, the cables segment of Cenergy Holdings, will supply and install approximately 38 km of 150kV submarine and land cables for a Greek project.

A press release said that the turnkey contract is from IPTO (Independent Power Transmission Operator), which is responsible for the operation, monitoring, maintenance, and development of the Hellenic Electricity Transmission System. It calls for 50 kV XLPE underground and submarine cables to enhance the electrical interconnections between Kefalonia-Zakynthos and Lefkada-Kefalonia, the Ionian islands in Greece.

The project is scheduled for completion in 2026. The submarine cables will be manufactured at the Hellenic Cables plant in Corinth, Greece. The capacity of that facility has recently been expanded, and it can manufacture continuous lengths for some of the longest submarine cables. The land cables will be manufactured at the company’s plant in Thiva, Greece, that has also seen a capacity expansion investment program.

Hellenic Cables, based in Greece, recently announced that it would supply cable for two projects, one in the U.S. and other for the Netherlands.

A press release said that Hellenic Cables will be a supplier to the Leading Light Wind project, a large U.S. offshore wind project located over 40 miles off the coast of New Jersey. The company will provide 65 km of 132 kV inter-array cables for Invenergy, the project’s lead developer, and co-developer energyRe. It noted that Leading Light Wind is the only American-led project in the New York Bight lease area. The delivery of the inter-array cables is scheduled for 2030, with the production of certain cable components starting immediately at the Hellenic Cable plant in Corinth.

Hellenic Cables is part of Cenergy Holdings. “Our contribution ... underscores (our) commitment to providing pioneering solutions that support the energy transition and enhance sustainability on a global scale,” said Cenergy Holdings CEO Alexis Alexiou.

Hellenic Cables also reported that it has a long-term agreement with Enexis Netbeheer (Enexis), one of the Netherland’s largest electricity network operators. Enexis is using eight cable suppliers as part of a €2.3 billion investment program to enhance power distribution infrastructure across five Dutch provinces.

Hellenic Cables will provide a portion of the power cable that will be needed over the next 12 years. That was estimated at 40,000 km of medium-voltage cables and 36,000 km of low-voltage cables to modernize local grids. “This project not only strengthens our presence in the Dutch power distribution market but also represents a sizeable step in Europe’s clean energy transition,” said Hellenic Cables General Manager Kostas Savvakis.

Hellenic Cables, the cables segment of Cenergy Holdings, announced that the South Fork Wind project has successfully powered up New York’s first offshore wind turbine, a major milestone in the construction of the first U.S. utility-scale offshore wind farm in federal waters.

A press release said that Hellenic Cables designed, manufactured, supplied, tested and terminated 30 km of 66 kV XLPE-insulated subsea inter-array cables and associated accessories. The cables were manufactured at Hellenic Cable’s plant in Corinth, Greece.

“This accomplishment reflects the dedication and expertise of everyone involved in this pioneering project,” said Alexis Alexiou, CEO of Cenergy Holdings. “We’re proud to work with industry leaders such as Ørsted and Eversource on a project that will help transform the US energy sector.”

Hellenic Cables already has a strong project pipeline in the U.S. offshore wind sector, with contracts for the supply of inter-array cables for flagship projects, including Revolution Wind in Connecticut and Rhode Island, Southcoast Wind in Massachusetts, and Dominion’s Coastal Virginia Offshore Wind.

Hellenic Cables, the cables segment of Cenergy Holdings that is based in Greece, has signed a contract to supply some 205 km of inter-array cables for the Bałtyk II and Bałtyk III offshore wind farms in Poland.

A press release said that the joint venture of Equinor and Polenergia has been developing the MWF Bałtyk II & III offshore wind farm projects in Poland. Hellenic Cables was appointed by Seaway7 as the key subcontractor for the design, manufacturing, testing and supply of up to approximately 205 km of 66 kV submarine inter-array cables and related accessories for these projects.

The Bałtyk II and III wind farms extend into 122 sq km and 117 sq km areas, respectively, strategically positioned in the southwestern Baltic Sea within Polish waters at depths from 20 to 45 m. Hellenic Cables will manufacture the submarine cables at its Corinth plant, with the schedule calling for delivery completed by the first half of 2026.

“We are delighted to be working with Hellenic Cables once again, following our successful collaboration on previous offshore wind projects,” said Seaway7 Project Manager Tom Rijnders.

Hellenic Cables notes that, through its fully owned subsidiary, Fulgor, the company’s Corinth plant can produce some of the world’s longest submarine cable lengths without factory joints.

Hellenic Cables has signed a contract with Seaway7 for the East Anglia THREE offshore wind farm which is being developed by ScottishPower Renewables (SPR).

A press release said that Hellenic Cables will be responsible for the engineering, manufacturing, testing and supply of some 275 km of 66 kV three-core inter array submarine cables and the supply of the associated accessories. Production will get underway in 2024. Once operational in 2026, it will be the second-largest offshore wind farm in the world. The cables will be manufactured at the company’s plant in Corinth, Greece.

“We are excited to have been awarded the cable supply contract ... and support the expansion of renewable energy in the UK,” said Hellenic Cables GM Konstantinos Savvakis. “We are proud to be part of this important project.”

The wind farm is located approximately 69 km NE off the Suffolk coast. Its 95 14.7MW turbines will have a combined capacity of 1,400 MW, generating enough green electricity to power the equivalent of more than 1.3 million homes.

Earlier this year, SPR awarded a contract for the high-voltage DC (HVDC) export power cable system for the East Anglia THREE offshore windfarm to NKT. The turnkey contract, with a contract value in excess of €250 million in market prices, comprises the design, manufacturing and installation of the complete 320 kV HVDC export power cable system.

SPR reports that East Anglia THREE will follow the same cable corridor as its flagship offshore windfarm – East Anglia ONE, which means that there is no need to create new cable trenches. “At ScottishPower, we’re committed to generating more homegrown green electricity in the U.K. for the U.K., and East Anglia THREE will be a huge part of that,” said Ross Ovens, managing director for the East Anglia Hub offshore windfarms.

Hellenic Cables has three cable production plants in Thiva and Corinth (Greece) and Bucharest (Romania) and two auxiliary production plants in Oinofyta (Greece) and Blagoevgrad (Bulgaria). The Corinth production unit was described as one of the largest and most advanced submarine cable plant in the world.

Hellenic Cables has won the contract to design, manufacture, transport, and install a package of four 220 kV HVAC export cables to connect the Baltyk II and Baltyk III wind farms in the Polish Baltic Sea to shore.

A press release said that the project—developed by the joint venture of Equinor and Polenergia, Baltyk II and Baltyk III—will each have a capacity of 720 MW and connect to the onshore grid via a total of four HVAC submarine cables with a combined length of 256 km.

Baltyk II and Baltyk III will be two of the first operational offshore wind farms in Poland, supporting the country in its transition to renewable energy. Hellenic Cables is part of a consortium that includes the De Nul Group, which will install them.

“We are proud that Equinor and Polenergia have awarded us to install the export cables for these 2 important Polish projects and their recognition of the combined capabilities of Jan De Nul and Hellenic Cables,” said Wouter Vermeersch, Manager Offshore Cables at Jan De Nul Group.

The companies will execute the connection of the two Baltyk wind farms to shore in 2026. The design and manufacture of the HVAC cables will be performed at Hellenic Cables’ plant in Corinth, Greece.

Hellenic Cables has been awarded a contract from TenneT for the turnkey delivery of approximately 36 km of HVAC offshore grid connection cables for offshore wind farms to be developed in zones (N-3.7 and N-3.8) in Germany.

A press release said that the project, being done in partnership with the Jan De Nul Group, is for the cabling that will connect the wind farms to the DolWin kappa converter station, from where HVDC cables transfer the produced energy to shore. Hellenic Cables will be responsible for designing, manufacturing, supplying, terminating, and testing of three 155kV HVAC grid connection cables and associated accessories.

Manufacturing is planned for 2025 in Hellenic Cables’ submarine cable plant in Corinth, Greece, and delivery is expected in Q3 2025. The Jan De Nul Group will handle the cable transportation, laying and protection works. A single cable will be installed between zone N-3.7 and the DolWin kappa converter, covering a length of 16.5 km. The N-3.8 zone will connect to the converter station by two cables, each about 10 km long.

Hellenic Cables is part of Cenergy Holdings, which itself is a subsidiary of Viohalco SA, a Belgian-based holding company that specializes in manufacturing aluminum, copper, cables, steel and steel pipes.

Hellenic Cables is one of 13 parties from eight countries that are part of a coalition working to further the design and deployment of a 6 MW floating wind prototype in the French Mediterranean.

A press release said that the pan-European project, launched in Paris, seeks to accelerate the roll out of the next generation of floating wind technology for a competitive, more scalable and industrial deployment. Other participants include: X1Wind, Naturgy, 2B Energy, Technical University of Denmark, Hydro, Ecole Centrale de Nantes, Schwartz Hautmont, Ocas, Tersan Shipyard, Ocean Ecostructures and Cybernetix.

Backed by the European Commission under the Horizon Europe program with public funding of €16 million, the project is anticipated to run until 2027. It will lead to the deployment of a 6 MW floating wind prototype to demonstrate at a relevant scale an innovative integrated downwind floating platform design, while advancing in parallel on the industrialization and scaling-up of the integrated solution up to 20MW+ scale, in preparation of commercial floating wind farms under development in Europe.

This project builds upon previous European Projects such as the PivotBuoy which recently led to the installation of a part-scale prototype in the Canary Islands to validate the technology. Design work for the initial 6MW system is currently underway and scheduled to be finalized in 2023. Construction is due in 2023 and 2024, ahead of installation in 2025.

Floating wind is considered one of the lowest carbon electricity generation systems to meet the energy demand in a sustainable way while inducing better competitiveness, less noise and visual pollution, and less interaction with the users of the maritime domain. The NextFloat Project represents a unique opportunity to test a novel and disruptive version of this technology at full scale, driving cost curve reductions in order to deliver industrial-scale projects at the earliest possible stage”.

“After the successful deployment and validation of our innovative low-cost solution in the Canary Islands (PivotBuoy project), the goal now is to scale-up and industrialize the technology in advance of large commercial floating wind projects which will come online at the end of the decade across European, Asian and U.S. waters,” said X1 Wind Founder and CEO Alex Raventos. “Wind will allow us time to drive substantial improvements in the competitiveness of floating wind as we prepare for long-term mass deployment.”
