Offshore Wind Cable Market Size
The offshore wind cable market was valued at USD 6.1 billion in 2025, is projected to reach USD 7.2 billion in 2026, and is expected to grow at a CAGR of 13.2% from 2026 to 2035, reaching USD 22 billion by 2035.
Offshore Wind Cable Market Key Takeaways
Market Leader: Prysmian Group led with over 28% market share in 2025.
Leading Players: Top 5 players in this market include Prysmian Group, NKT A/S, Nexans SA, LS Cable & System, Hellenic Cables, which collectively held a market share of 81% in 2025.
The market's expansion reflects an increasingly infrastructure-intensive phase of offshore wind deployment. Larger projects, more distant sites, grid-connection requirements, and a widening mix of fixed and floating installations are shifting procurement toward higher-value export, inter-array, and specialized dynamic cable systems.
GMI Analyst View
Our discussions with industry experts indicate that the offshore wind cable market delivered approximately 6,854 km of cable volume in 2025, reflecting the translation of a broadening project commissioning pipeline into measurable supply throughput. This volume baseline establishes the pace at which the infrastructure ramp-driven by secured auction awards and advancing project timelines across key markets-is converting from contractual order flow into physical delivery and underpins the revenue trajectory captured in the GMI forecast.
Offshore Wind Cable Market Trends, Growth Drivers & GMI Forecast Outlook
Offshore wind cable demand is being shaped by the interaction of expanding auction pipelines, higher-capacity transmission architectures, and constrained specialist supply. The result is a market in which booked manufacturing capacity and installation readiness increasingly determine when project demand converts into recognized cable revenue.
Key Drivers
Evidence anchors use cited external data; demand implications and forecast conditions represent GMI analysis.
Global offshore wind installed capacity reached 83 GW by the end of 2024, underscoring the scale of the installed base from which repowering, grid reinforcement, and new-build cable demand can develop [1]Global Wind Energy Council. "Offshore Wind Installed Capacity Reaches 83 GW as New Report Finds 2024 a Record Year for Construction and Auctions." gwec.net. Auction awards matter because they transform policy ambition into a defined project pipeline, allowing developers, transmission operators, and EPCI contractors to reserve manufacturing slots before construction begins.
Higher-capacity export architectures are also changing the market's revenue composition. As projects move farther offshore and aggregate more generation behind fewer connections, suppliers capable of engineering, qualifying, and manufacturing advanced HVDC systems can address contracts with greater material intensity and more demanding installation requirements. Floating wind adds another layer of opportunity by introducing dynamic-cable needs that conventional static cable designs do not serve.
Key Restraints
Evidence anchors use cited external data; demand implications and forecast conditions represent GMI analysis.
HVDC supply constraints can delay projects even after seabed rights, offtake arrangements, and grid approvals are in place. The limited number of qualified suppliers gives production-slot availability substantial influence over project sequencing, while more than USD 5 billion in NKT high-voltage contract awards and booking commitments since March 2023 illustrates the depth of committed demand confronting the specialist supply base [2]International Energy Agency. "Building the Future Transmission Grid." iea.blob.core.windows.net.
Raw-material exposure compounds this constraint because cable contracts are negotiated well before delivery. Copper-cost volatility can pressure fixed-price commitments and encourage developers to consider aluminum where voltage requirements, grid codes, and engineering design permit substitution. Separately, the limited availability of capable cable-lay vessels can move commissioning dates even when cable manufacturing milestones have been met.
GMI Analyst View
We view the market's central tension as one between highly visible project demand and a supply chain that cannot expand qualification, manufacturing, and marine-installation capability at the same pace. Framework agreements are therefore becoming strategic instruments for delivery assurance, reinforcing the value of established supplier relationships and shifting a greater share of demand realization toward later project milestones.
Offshore Wind Cable Market Segment Analysis
By End Use
The offshore wind cable market is moving toward product configurations that accommodate larger turbines, longer export routes, and the emerging commercial requirements of floating projects.
Inter-Array 11-33 kV
Inter-Array 11-33 kV cables generated USD 1.64 billion in 2025 and are projected to reach USD 3.52 billion by 2035. Their installed-base relevance remains material, particularly for repowering programs and near-shore developments built around established electrical architectures. However, new projects increasingly favor higher-voltage inter-array specifications where turbine ratings and array design justify the shift.
Inter-Array 34-66 kV
Inter-Array 34-66 kV cables accounted for 18% of market revenue in 2025 and are projected to reach USD 5.28 billion by 2035. This segment benefits directly from turbine scaling because higher-voltage collection systems can transmit more power while avoiding impractically large conductor cross-sections. Its adoption is most consequential in large utility-scale arrays where electrical losses, installation efficiency, and turbine spacing shape lifetime economics.
Export HVAC ≤132 kV
Export HVAC ≤132 kV cables generated USD 1.34 billion in 2025 and are expected to grow at a CAGR of 12.0% from 2026 to 2035. HVAC remains a practical solution for projects with manageable shore distances and established AC grid interfaces. The segment is consequently supported by fixed-foundation developments in shallower waters, even as longer-distance projects increasingly require alternative transmission configurations.
Export HVDC >132 kV
Export HVDC >132 kV cables generated USD 1.70 billion in 2025 and are projected to reach USD 6.38 billion by 2035. This category is central to the market's shift toward larger, more remote projects because high-voltage direct-current transmission supports efficient evacuation of power across longer routes. Its growth also carries a supply-chain implication: engineering expertise, factory capability, and system qualification become decisive competitive differentiators.
Dynamic Cables
Dynamic cables generated USD 305 million in 2025 and are expected to grow at a CAGR of 21.1% from 2026 to 2035. Their role is tied to floating offshore wind platforms, where cable systems must withstand repeated motion, bending, and fatigue loading. This creates a specialist product category in which design reliability and accumulated operating references can matter as much as manufacturing scale.
By Conductor Material
Copper
Copper conductors generated USD 3.29 billion in 2025 and are expected to represent 50% of market revenue by 2035. Copper retains a structural advantage in applications where conductivity, cable diameter, weight, and deep-water installation stresses are critical design considerations. It is particularly important in demanding export-cable configurations, where substitution may be constrained by system specifications and qualification requirements.
Aluminum
Aluminum conductors generated USD 2.80 billion in 2025 and are expected to grow at a CAGR of 14.3% from 2026 to 2035. Aluminum is gaining relevance in medium-voltage inter-array procurement where project economics favor lower material costs and engineering requirements permit its use. Its expansion reflects a broader effort by developers to manage cable-system cost exposure without compromising technical performance.
GMI Analyst View
We see product mix evolving along two distinct paths: higher-voltage systems are increasing the strategic value of advanced export-cable capability, while floating wind is creating a specialized engineering market for dynamic solutions. Suppliers that can serve both transitions are likely to gain disproportionate access to the most technically demanding project packages.
