By Voltage Level, Medium Voltage (MV) segment dominates the Offshore Wind Cable Market, Extra High-voltage (EHV) Cables segment expected to grow fastest

Medium Voltage (MV)

Why the Segment is Important: The Medium Voltage cables are the key segment of the electrical infrastructure that is necessary in every offshore wind farm irrespective of its size because the inter-array collection system cables are always a vital part of electrical infrastructure for any offshore projects. The importance of this segment is driven by the high demand of this segment, as inter-array cables are always in high demand due to the high volume of inter-array circuits.

Growth Outlook: The growth rate in the medium voltage segment is forecasted to be relatively low compared to others and at 17.74% for the period between 2026-2035 as it is the most developed segment with limited changes except for building new projects. Although there will be additional value for the segment with the increasing shift towards high voltage inter-array circuits up to 66 kV from 33 kV.

Extra High Voltage (EHV)

Why the Segment is Important: Extra high voltage cables, although comprising only a small share of the current market by value, are at the cutting edge of offshore wind technology and demand, as EHV systems are incorporated in designs for larger generation clusters while also being specified for future offshore grid interconnection projects that will mark the next stage in developing the industry.

Growth Outlook: The EHV segment is expected to grow at the highest growth rate among all voltage level categories and one of the highest growth rates across the entire segment analysis between 2026-35 with a CAGR of 24.58%, directly reflective of an accelerating pipeline of both gigawatt-scale offshore wind projects as well as initiatives to develop offshore grid interconnectors that will rely on export and interconnection cable systems rated for high voltages (EHV).

By Current Type, AC Cables segment dominates the Offshore Wind Cable Market, DC Cables segment expected to grow fastest

AC Cables

Why the Segment is Important: AC cables are the basis of all inter-array cables in offshore wind farms as well as the dominant technology used in export transmissions in most existing offshore wind energy projects. The significance of this segment lies in the fact that it is both the de facto solution and most cost-effective one for a vast majority of configurations, thanks to an already established supply chain, industry standards, and decades of experience in offshore wind and oil and gas subsea cable sectors.

Growth Outlook: It is expected that the segment of AC cables will see a growth rate of 18.46% from 2026 to 2035, which is somewhat lower than the average for the whole market but still positive, owing mainly to steady volumes of sales due to demand for inter-array cables in all offshore wind projects, even though an increasing number of offshore wind energy projects favor DC export transmissions in larger projects located farther off the shore.

DC Cables

Why the Segment is Important: The DC cables play an important role as the enabling technology required to realize offshore wind development projects on a large scale far from the coast. This involves the connection of several gigawatt offshore wind parks through shared high voltage direct current transmission systems within the North Sea's offshore wind power hubs. The importance of this segment can be seen in the offshore grid integration concept, which includes DC cables for use in multi-terminal networks and interconnectors spanning across multiple projects.

Growth Outlook: The growth forecast in the DC cable segment shows a CAGR of 22.48% from 2026 to 2035, which is the higher of the two type segments, thanks to a growing pipeline of large-scale offshore wind farms located further out than economically feasible AC transmission distances and increasing policy interest and developer enthusiasm in offshore grid projects using DC transmission technology.

By Cable Type, Inter-Array Cables segment dominates the Offshore Wind Cable Market, Dynamic Cables segment expected to grow fastest

Inter-Array Cables

Why the Segment is Important: Inter-array cables form the biggest volume category of cables by the length installed on a project basis because every turbine within an offshore wind farm needs to be interconnected with neighboring turbines, and with the offshore substation as well. Such importance is accentuated by the high volume of turbines installed within modern offshore wind farms, where projects comprising up to 80 to 100+ turbines contribute to high total lengths of inter-array cables, correlating with the total electrical installation cost.

Growth Outlook: The segment is forecasted to experience the slowest growth pace at CAGR of 17.98% in the period of 2026-2035 compared to other two categories of cables, owing to its rather high penetration rate and fairly developed standards of inter-array medium voltage cables within the industry. Growth will be driven by the continuous expansion of global offshore wind power capacities, with new growth drivers provided by increased turbine unit capacities allowing for decreasing cable consumption on megawatt basis.

Dynamic Cables

Why the Segment is Important: dynamic cables constitute the least proportion of the cable type segmentation in terms of volume, they have a very vital significance to the future development of offshore wind power, considering their critical importance in floating offshore wind turbines that are essential for tapping into deep water offshore wind resources. The importance of dynamic cables comes from the fact that without dynamic cables, it would not be possible to develop floating offshore wind projects economically.

Growth Outlook: Dynamic cables have the greatest growth potential among all segments analyzed under the cable type segmentation category, growing at a CAGR of 21.67% during the years 2026-2035, thanks to the expanding pipeline of demonstration and commercial offshore floating wind projects in deep water areas such as the Mediterranean, Celtic Sea, West coast of America, and some parts of Asia Pacific.
