• Nexans will deliver HVAC subsea export cables for South Fork Wind Farm, the first delivery of Nexans’ framework agreement to supply Ørsted and Eversource with up to 1,000 km of high voltage subsea cables in the U.S.
• The South Fork Wind Farm will address East Hampton’s energy needs, producing enough clean energy to power 70,000 homes.
• The HVAC cables will be manufactured in Nexans’ newly transformed subsea high voltage cable plant in Charleston, South Carolina, the only facility in the U.S. capable of manufacturing high voltage subsea cable.

Nexans has received the first order under the frame agreement to manufacture approximately 110km of high voltage subsea cables to South Fork Wind, a joint venture between Ørsted and Eversource. The 3-phase 138 kV high voltage alternative current (HVAC) subsea export cables will be integrated with two fiber-optic cables and transmit 132 MW of electricity to Long Island, New York.

Located 35 miles offshore from Montauk Point, New York, the 132 MW South Fork Wind Farm will address East Hampton’s energy needs, producing enough clean energy to power 70,000 homes annually. The historic project will be the New York state’s first offshore wind farm and will play a key role in reaching the state’s clean energy goals. Construction will start in 2022.

The Export Cable Framework Agreement, providing the opportunity to supply up to 1,000km of high voltage subsea cables in the U.S. by 2027, was signed in December 2019 between Ørsted Wind Power North America LLC and Nexans to accelerate the energy transition in North America by bringing Nexans’ industry-leading subsea cable technology to the U.S. This contract is the first project to be delivered under this agreement.

The HVAC cables will be manufactured at Nexans’ newly transformed subsea high voltage plant in Charleston, South Carolina, the only plant in the U.S. capable of manufacturing high voltage subsea cables. It is a critical part of building out the strategic supply chain for offshore wind industry in the U.S.

• Nexans subsea and land cables will provide power for up to 1 million Scottish homes helping the UK achieve its clean energy targets.
• Project for SSE Renewables confirms Nexans’ position as a key strategic partner in the global energy transition.
• Contract is part of Nexans’ current €1.6bn order backlog for subsea cable projects.
• The subsea export cables will be installed by Nexans’ new Aurora cable laying vessel.

Nexans has been awarded a major contract by SSE Renewables to design, manufacture and install the high voltage (HV) onshore and offshore export cables for the Phase 1 development of the Seagreen offshore wind farm project. Construction on the 1,075 megawatt (MW) project, which is located 27km off the coast of Angus, will start next year. When completed in 2022/23 Seagreen 1 will be Scotland’s largest wind farm and single largest source of renewable energy, providing a significant contribution to Scotland’s net zero ambition and enough clean, renewable energy to power 1 million homes.

Nexans’ factory in Charleston, US will supply the three 65 km offshore export cables. This factory was recently expanded to manufacture HV subsea power cables and is currently the only facility with that capability in North America. The three 20 km onshore export cables for the project will be manufactured at Nexans’ factory in Charleroi, Belgium.

Nexans is committed to working closely with suppliers local to the Seagreen project on subcontract opportunities available, including both the offshore and the land part of the contract.

The export cables for the Seagreen offshore windfarm project will be installed by the Aurora, Nexans’ brand new cable laying vessel (CLV).The Aurora is currently under construction and will be delivered in the second quarter of 2021.

The electricity generated by the Seagreen turbines will be transmitted via the subsea export cables to landfall at Carnoustie. Once ashore, the land cables will transmit the electricity to a new substation at Tealing where it will feed in to the UK’s national electricity transmission system.

• The new interconnection will enable Crete’s renewable energy transition by providing a one gigawatt (GW) link between the island Crete and Greece’s mainland network.
• Nexans will design, manufacture and lay 335 kilometers of subsea HVDC cable at water depths down to 1,200 meters.
• Contract value exceeds €220m and is part of Nexans’ current €1.6bn order backlog for subsea cable projects.

Nexans has been awarded a major contract to design, manufacture and install a 335km subsea high voltage direct current (HVDC) cable system for Ariadne Interconnection S.P.S.A, owned 100 percent by IPTO, Greece’s state grid operator. The interconnection will link the electricity network on mainland Greece to Crete. The project will provide security of supply for the island and enables the transition from fossil fuel generation to renewable wind and solar energy resources.

Crete is the largest of the Greek islands, with a population of around 700,000 people. It also attracts over 4 million visitors a year, mainly during the summer. The island currently relies mainly on out-dated fossil fuel generation. The new submarine cable interconnection will ensure that Crete has a reliable power supply essential for its future prosperity. The interconnection will also reduce emissions, making the island even more attractive to tourists, and also helping it to develop its own renewable energy resources by enabling excess generation to be exported back to the mainland.

The cable will span a subsea distance of 335 km from the Attica region on the Greek mainland to the Herakleion area in Crete. Over a 35-month project, Nexans will provide one 500 megawatt (MW) HVDC subsea cable system to form half of the total 1,000 MW bipole interconnection.

The Nexans cable, rated at 500,000 Volt, is based on its well-proven mass impregnated nondraining (MIND) design for HVDC cable systems and will integrate fiber optic elements for sensor applications. The near-shore sections of the cable, to be installed at water depths down to 100 meters, will feature an aluminium conductor core with a cross-section of 1,800 mm². The deeper sections of the cable, installed at depths down to 1,200 meters, will feature a 1,500 mm² crosssection aluminium conductor. The cable will be protected by trenching into the seabed using the Nexans Capjet water jetting system down to 600 meters water depth.

The HVDC cable will be manufactured in the Nexans plant in Halden, Norway and/or the plant in Futtsu, Japan. It will be installed by one of Nexans’ own dedicated cable vessels – Nexans Skagerrak or new Nexans Aurora. The interconnection is scheduled to come on line in 2023.

• Nexans has won a contract worth over 150 million euros to help Ørsted deliver the most affordable electricity from offshore wind yet.
• The project covers the supply of over 200 km of the 245 kV high voltage alternating current (HVAC) subsea export cable system for the near shore section of Hornsea 2 wind farm.

Today, many nations are harnessing renewable energy sources with the aim of counteracting climate change, one of the world’s biggest challenges. In 2017, Europe installed 16.8 GW of additional wind power capacity making it the second largest form of power generation in the region. One of the latest most prominent wind power developments is Ørsted’s Hornsea 2 project, for which Nexans has been awarded a contract worth over 150 million euros to supply over 200 km of 245 kV cross-linked polyethylene insulated (XLPE) near shore export cable system.

Located in the North Sea, approximately 89 km from the Yorkshire coast, the 1.4 GW offshore wind farm will be the world’s largest once it starts operating. The wind farm, which is the sister project to Hornsea 1, will provide enough electricity to power over 1.3 million homes. Ørsted is now constructing the project, with completion set for 2022.

To bring the electricity produced by the windfarm onshore, the project will be equipped with Nexans three-core HVAC submarine cables. These 245 kV XLPE cables will be part of the near shore section of the export circuits linking the wind farm’s reactive power substation to the onshore substation. The circuits will comprise three individual near shore export cables and will follow a similar route to Hornsea 1, for which Nexans Germany has earlier supplied 139 km of three-phase 36 kV subsea cable inter-linking a total of 58 wind turbines and connecting them to the offshore transformer station. The route will make landfall at Horseshoe Point from where land cables will feed the power to North Killingholme onshore substation.

These cables for Hornsea 2 project will be manufactured at Nexans Norway site in Halden.

The Netherlands is planning to increase its use of renewable energy to represent 14% of its energy mix in 2020 and 16% in 2023. Offshore wind energy is a vital element in this transition and a major milestone will be reached in 2020 when Ørsted brings its Borssele 1 and 2 wind farms online. Nexans is playing a key role in the project by supplying a total length of between 170 km and 190 km of subsea cable rated at a maximum operating voltage of 72.5 kilovolt (kV) to provide the inter-array connections between the turbines and the offshore substations in the framework of a multimillion-euro contract.

Borssele 1 and 2 are located around 23 km off the Dutch coast in 14 to 36 meters of water. Together, the two wind farms will have a total of 94 wind turbines generating 752 megawatt (MW) of power, which is enough electricity to meet the needs of around one million domestic households.

As part of a new five-year framework agreement, Nexans has been awarded a contract by Ørsted to supply and install three-phase 66 kV copper cables with two cross-sections. They will be used for internal cabling of the wind farms: the array cables connect the wind turbines to each other and to the transformer stations where the electricity is transported to the mainland.

In addition to the inter-array cables, Nexans is also providing the relevant fittings and accessories for the project, including T-connectors for the 66 kV cables designed for wind farm application with a standardised, robust and easy plug and screw solution.

Nexans has previously supplied Ørsted (formerly Dong Energy) with submarine cables for a number of offshore wind farms. Furthermore, Nexans’ portfolio of cutting-edge accessories is already connecting the three of the world’s first 66 kV wind farm pilot projects commissioned in the North Sea over the past two years.

The array cables for Borssele 1 and 2 will be produced at the Nexans Germany plant in Hanover for delivery in 2019. After they have been laid in place on the seabed, Nexans Subsea and Land Systems will complete connection to the turbine bases using in-house jointing expertise in 2020. The cable accessories will be supplied by Nexans Euromold facility based in Erembodegem, Belgium.
