Hellenic Cables, the cables segment of Cenergy Holdings, in consortium with Asso.subsea, was awarded a turnkey contract from Réseau de Transport d’ Électricité (RTE) —the sole operator of France’s public electricity transmission network—to supply the cable for the Dunkirk Offshore Wind Farm.

A press release said that Hellenic Cables will design, manufacture and supply 32 km of submarine cables for the double submarine cable link, as well as 38 km of underground cables for the tri-phased double underground cable link, supply submarine and underground cable accessories.  The submarine cables will be manufactured at the company’s plant in Corinth and the land cables at its plant in Thiva, which is currently undergoing a capacity expansion project. The company will also perform on site jointing, testing and termination works and be responsible for the commissioning of the cable links wind farm.

The wind farm, which has a planned capacity between 500 MW and 600 MW, will feature two 225 kV HVAC export cable links which will enable the seamless transfer of clean energy to the French grid. The wind turbines will be spaced around 1 km apart to ensure that the offshore wind farm operates at optimum efficiency.  The project involves complex laying and burial operations in shallow waters.

“This project is an important step forward in supporting France’s renewable energy goals and Hellenic Cables is honored to continue its collaboration with RTE,” said Hellenic Cables General Manager Kostas Savvakis, General Manager. “Our role in the Dunkerque Offshore Wind Farm highlights Hellenic Cables’ commitment to delivering reliable and sustainable energy solutions, while fostering strong collaborations with industry leaders like RTE and Asso.subsea.”

 Hellenic Cables has been awarded a U.S. contract for the Silver Run Expansion Project that calls for the addition of new submarine cables adjacent to existing cables currently in service beneath the Delaware River.

A press release said that the project includes the supply of 21 km of single-core, AC high-voltage 230 kV submarine XLPE insulated power cables. The submarine cables will be manufactured at Hellenic Cables’ plant in Corinth, Greece. Manufacturing is set to be completed in the first half of 2026. The cables will form part of a critical power transmission line between New Jersey and Delaware across the Delaware River.

The additional cables will enable the transmission line between the Silver Run substation in Delaware and the Hope Creek substation in New Jersey to accommodate additional electrical flows. New transition structures will be installed at the termination points of the new submarine cable to connect the new cable to the existing overhead transmission line. Equipment at Silver Run substation will also be upgraded as required to serve the additional line capacity.

The project is owned by Silver Run Electric LLC, an affiliate of LS Power, a leading development, investment, and operating company focused on the North American power and energy infrastructure sector, and its wholly owned subsidiary, LS Power Grid, a national electric transmission system developer, owner, and operator.

Hellenic Cables, the cables segment of Cenergy Holdings, has signed a framework agreement with National Grid, that secures its position as one of the appointed contractors eligible to participate in future HVDC cable projects across the U.K. and Europe.

A press release said that the agreement will enable it—and Jan De Nul, a global offshore installation contractor it has formed a consortium with—to participate in upcoming tenders for call-off projects for the design, manufacturing, supply, installation, testing, and commissioning of HVDC cable systems as part of National Grid’s large-scale offshore and onshore transmission infrastructure investment program. This framework agreement, which has an initial term of five years with an option for extension of up to three additional years, is a key component of National Grid’s strategy to secure long-term partnerships that support deliverability for critical projects in the U.K.

The U.K. Government’s commitment to achieving Net Zero by 2050 has placed significant emphasis on expanding the country’s electricity infrastructure to integrate renewable energy sources, such as offshore wind. National Grid’s cable framework aims to support this transition, ensuring a robust and reliable energy network. This framework will play a crucial role in enhancing grid resilience, facilitating renewable energy integration, and ensuring energy security for the future.

The consortium will participate in potential future tenders for turnkey projects. Hellenic Cables is undergoing a strategic investment program to expand production capacity and enhance technological capabilities for its plants in facilities in Corinth and Thiva. 

Jan De Nul has invested in two cable-laying vessels that will make it possible for the consortium to meet the expected future needs stemming from the development of HVDC interconnector projects.

“This agreement strengthens our commitment to supporting the UK’s energy transition and offshore wind ambitions,” said Hellenic Cables General Manager Kostas Savvakis. “We are proud to be part of this critical framework, providing world-class HVDC cable solutions.”

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.
