The global wind turbine components market was valued at USD 18.5 billion in 2025. The market is projected to grow from USD 20.05 billion in 2026 to USD 39.02 billion by 2034, exhibiting a compound annual growth rate of 8.68% during the forecast period. Contrive Datum Insights presents this information in its report titled "Wind Turbine Components Market Size, Share & Industry Analysis, By Component type (Blades, Towers, Gearboxes, Generators, Nacelle Systems, Electrical & Control Systems), Installation type (Onshore, Offshore), Material (Steel, Composite & Fiberglass, Others), Rated capacity band (Below 2 MW, 2 to 4 MW, Above 4 MW), Sourcing channel (OEM Captive Production, Independent Component Suppliers), and Regional Forecast, 2026-2034".
Wind turbine components cover the manufactured subsystems, blades, towers, gearboxes, generators, nacelle assemblies and electrical and control systems, that are engineered and assembled into onshore and offshore wind turbines. Buyers are turbine original equipment manufacturers sourcing these subsystems for new installations and repowering projects, along with the tier-one fabricators and materials suppliers that manufacture them under long-term supply agreements.
Offshore wind capacity expansion
Offshore wind capacity expansion is the largest single contributor to the market's growth over the forecast period, and the study rates its impact high. Against a market growing at 8.68% a year, the component type lines exposed to it move fastest: Electrical & Control Systems compounds at 13.13%, taking its share of revenue from 9% to 13% and its value from USD 1.67 billion to USD 5.07 billion.
The study also runs a bull case: bull assumes offshore lease auctions clear on schedule and steel and logistics costs ease faster than the base case, lifting installed capacity and component content per turbine above the base path. That path ends 2034 at USD 44.87 billion, above the USD 39.02 billion base case.
On the downside, bear assumes permitting delays slow offshore capacity additions and mature-market subsidy phase-outs reduce onshore repowering activity, holding component demand below the base path, which would hold 2034 revenue to USD 33.56 billion. Gearboxes, which carries 14% of 2025 revenue, already grows at only 4.61% against the market's 8.68%, so the largest part of the base is also its slowest.
Key Players Compete on Blades Volume and Electrical & Control Systems Growth
Competition in the global wind turbine components market runs along the component type axis, not the regional one. Blades holds 28% of 2025 revenue at USD 5.18 billion and remains the largest line through 2034 at 29%, making it the position hardest for a challenger to take. Electrical & Control Systems, growing at 13.13%, is where share actually changes hands. A supplier established in one is not thereby established in the other, so a field of this size persists in a market of USD 18.5 billion.
