Three European companies control ~75% of the global subsea HV cable market.
High voltage subsea cables are becoming more critical in the offshore wind supply chain, as projects moving further from shore require HVDC technology.
By 2030:
- Offshore wind build-out is set to double
- Export cable routes are getting longer
- Interconnectors are competing for the same supply chain
But not every cable supplier can deliver at scale. The market is consolidating around roughly a dozen players with proven capability, while demand continues to grow on the back of larger wind farms, longer export routes, and HVDC interconnector build-out.
Aegir Insights has mapped the global subsea high voltage cable market:
- Three European majors hold a combined ~75% of the global subsea high voltage cable market, with full HVAC and HVDC capability, own CLV fleets, and deep order backlogs.
- Cable majors are vertically integrating into installation, burial, and lifecycle services, potentially partly in response to cable-related insurance claims.
- Chinese manufacturers are expanding internationally targeting Europe and the Middle East, and bolstering their presence with local partnerships.
The gap between companies that announce offshore wind cable capability and those that can deliver it at scale is wider than most expect. And this gap could become one of the defining bottlenecks for offshore wind deployment this decade.
