Wind Energy – Cable Systems
TenneT selects NKT and Prysmian for world’s largest offshore cable systems to connect increasing Dutch offshore wind volumes
The awarding of the world’s first 525 kV XLPE HVDC offshore cable connection systems for five Dutch 2 GW projects is the next step in realising the new 2 GW standard.
In the next months, TenneT expects to announce the partners for the Framework agreements of the 2 GW HVDC suppliers for Dutch and German 2GW projects and partners for the Framework agreement for cable connections of other 2 GW projects.
Tim Meyerjürgens, COO TenneT says: “Recent geopolitical developments have again underlined the need to invest in electricity transmission, to ensure energy security by accelerating the energy transition. We are proud that we developed this new offshore grid solution together with the market. Our qualification program has shown that cable suppliers are on track for this new offshore connection standard. By realising the world’s first 525 kV XLPE HVDC offshore cable systems to connect 2 GW projects, TenneT reconfirms its front runner position in offshore grid development and its commitment to deliver on the joint ambition to develop the North Sea into the green power plant of Europe.”
NKT will realise the cable connections for IJmuiden Ver Beta, IJmuiden Ver Gamma and Nederwiek 2, landing onshore at Maasvlakte (Port of Rotterdam).
Prysmian has been awarded a contract for the cable connections of IJmuiden Ver Alpha and Nederwiek 1, landing onshore at Sloegebied (Zeeland).
The scope of work in the contracts includes design, engineering, production, delivery, project management, offshore-, nearshore- and inshore installation of 525 kV HVDC cables and all jointing works in submarine and land sections.
The selected parties expect to start activities this year. Onshore cable laying activities starts in 2025, offshore cable laying activities are expected to start in 2026. All projects are expected to be in operation between 2028 and 2030.
