Project Experience

EolMed’s Floating Wind Turbines, France – 66kV Dynamic Inter-Array Cables

For the EolMed pre-commercial 30MW floating offshore wind project in the Occitanie region of France, JDR Cable Systems is providing 66kV dynamic inter-array cables to connect three floating wind turbines anchored in 60 meters of water depth. This project will generate approximately 100 million kWh annually, feeding power into the French Electricity Transmission Network. The cables, manufactured and tested at JDR's Hartlepool facility, will be installed by Bourbon Offshore Gaïa. This project supports France's ambition to achieve 40GW of offshore wind capacity by 2050 and represents a significant step in advancing floating wind turbine technology.

Baltic Power

In 2023, JDR signed a contract for the development of the Baltic Power offshore wind farm in Poland. The project involves the design, manufacture, and installation of 340 km of both onshore and subsea cables. Located 23 km off the Polish coast, the farm will cover approximately 130 square kilometers and will feature 76 wind turbines, each with a capacity of 15 MW. Once completed in 2026, the farm will generate a total capacity of 1.2 GW, enough to power over 1.5 million households with clean energy. The cables to be produced and installed include 230 kV onshore export cables and inter-array cable components, which will be produced at the Bydgoszcz manufacturing plant. The production and delivery of all subsea cables are scheduled for the end of 2025, contributing to the further development of renewable energy in Poland.

Moray West

JDR successfully delivered 139 km of 66 kV Array cables, connecting 60 wind turbines at the Moray West offshore wind farm in Scotland. With a total capacity of 882 MW, the farm is a significant step in the development of offshore wind energy and helps meet the growing demand for energy in the UK. The project also involved the production of the longest 66 kV cable, a continuous 14.5 km length with a cross-section of 800 mm². The subsea inter-array cables provide a reliable connection between the turbines and offshore substations, enabling the efficient transmission of the 882 MW of energy produced by the farm.

EnBW He Dreiht

JDR delivered 100 km of 66 kV Array cables, connecting 64 wind turbines at the EnBW He Dreiht offshore wind farm in Germany. With a capacity of 900 MW, this project is a key part of Germany's renewable energy goals. JDR was selected as the supplier for the inter-array cables, linking the 64 turbines in the North Sea's German exclusive economic zone. Upon its planned commissioning in 2025, the project will be the first to use 15 MW turbines, further advancing and increasing the efficiency of offshore wind energy in the region.

Arcadis Ost 1

JDR supplied 33 kV subsea cables for the Arcadis Ost 1 wind farm, located in German waters of the Baltic Sea, northeast of the island of Rügen. This 257 MW wind farm plays a key role in advancing Germany’s renewable energy sector.

Kriegers Flak

JDR completed the production and delivery of 170 km of aluminium core inter-array cables for the Kriegers Flak wind farm, one of Denmark’s key renewable energy projects. The cables, which were produced at JDR’s Bydgoszcz and Hartlepool facilities, form an essential part of the wind farm’s power transmission infrastructure. Upon completion, the Kriegers Flak wind farm will have 72 turbines, each with a capacity of 8.4 MW, providing 605 MW of power—enough to supply over 600,000 Danish households, representing around 23% of Denmark’s energy needs.

Vineyard Wind 1 Offshore Wind Farm, USA – Manufacturing and Supplying Array Cables and Accessories

JDR Cable Systems made a significant contribution to the Vineyard Wind 1 project, the first industrial-scale offshore wind farm in the United States, located off the coast of Massachusetts. This 800 MW project powers over 400,000 homes. JDR was responsible for manufacturing and supplying approximately 130 miles of 66kV inter-array cables and conducting their termination and testing. These cables connected wind turbines to offshore substations for efficient power transmission to the grid. The project, which began installation in 2023, marked a milestone in US offshore wind development, contributing to the country’s sustainable energy goals.

Leucate-Le Baracés

JDR supplied 66 kV dynamic cables for the Leucate-Le Barcarès floating wind farm, one of the largest floating offshore wind farms in France. This project is part of Europe's efforts to increase the share of renewable energy in the region’s energy mix.

Dan Tysk Offshore Wind Farm, Germany

Located 70 km off the coast of Sylt, the Dan Tysk offshore wind farm has a total capacity of 288 MW. JDR designed and manufactured two inter-array cables, totalling 7.5 km in length. The cables, along with accessories, were delivered within 10 weeks, contributing to the wind farm’s success and providing power to 400,000 households.

Changhua Offshore Wind Farm

The Changhua project, located off the coast of Fangyuan in Changhua County, central Taiwan, involves the installation and commissioning of 21 offshore wind turbines with a total capacity of 110 MW. In the first phase of the project, 63 km of 33 kV Cu 630 mm² inter-array cables and export cables were supplied to transmit power from the wind turbines to the shore. The installation was completed in 2020. The wind farm consists of 21 turbines, each with a capacity of 5.2 MW.

Once fully operational, the four wind projects, including Formosa 1 and Changhua, will form the largest offshore wind energy complex in Taiwan, with a total capacity of 2.4 GW, enough to provide renewable energy to around 2.8 million households in the country.

East Anglia One – The First Commercial Wind Farm with 66kV Cables

JDR was selected to supply 155km of 66kV inter-array cables for Scottish Power Renewables' East Anglia One offshore wind farm, the first commercial use of 66kV cable technology. This 714MW project will power 500,000 homes and is set for completion in 2020. The cables were manufactured at JDR’s Hartlepool facility.
