The global wind turbine generator market was valued at over USD 25.6 billion in 2025 and is projected to register a compound annual growth rate of approximately 8.6% from 2026 to 2035. The market continues to expand alongside the broader wind turbine industry, with permanent magnet synchronous generators capturing a growing share of new installations given their efficiency and reliability advantages relative to conventional induction and electrically excited synchronous designs. The market covers asynchronous, synchronous, and permanent magnet generator technologies used across both geared and direct drive turbine configurations, sold to original equipment manufacturers either as integrated drivetrain components or as standalone units. Direct-drive permanent magnet generator technology has continued advancing to support record single-unit capacity ratings, with manufacturers including Goldwind installing the world’s first offshore 20 megawatt wind turbine in China, illustrating how rapidly generator technology has scaled to support ever-larger turbine platforms.
The market is expected to grow steadily through the forecast period, owing to continued offshore wind capacity scaling that favors larger, higher-torque generator designs, growing adoption of permanent magnet technology across both onshore and offshore applications, and ongoing supply chain investment addressing rare earth material requirements specific to permanent magnet generator manufacturing. Generator weight and size continue to increase as direct-drive designs scale to higher torque ratings, requiring more permanent magnet material and more demanding mechanical structures, a dynamic that continues to shape manufacturing, supply chain, and installation considerations across the industry.
What is the size and growth rate of the global wind turbine generator market?
The market was valued at over USD 25.6 billion in 2025 and is projected to grow at approximately an 8.6% compound annual growth rate from 2026 to 2035, supported by continued offshore capacity scaling and growing permanent magnet adoption.
What generator technology has gained the most share within new wind turbine installations recently?
Permanent magnet synchronous generators continue capturing growing share given their efficiency and reliability advantages, with manufacturers including Goldwind built specifically around proprietary permanent magnet direct-drive technology.
What is the largest single wind turbine generator capacity currently installed globally?
Goldwind, in collaboration with China Three Gorges, installed the world’s first offshore 20 megawatt wind turbine in Fujian, China, marking a global industry first for single-unit generator capacity.
Why do larger direct-drive generators require disproportionately more permanent magnet material as capacity increases?
As torque ratings increase, direct-drive generators grow larger and heavier, requiring substantially more permanent magnet material and more demanding mechanical structures, creating design, supply chain, and manufacturing challenges for original equipment manufacturers.
How are manufacturers addressing reliability concerns specific to offshore generator applications?
Direct-drive generator designs without a gearbox continue to be favored offshore specifically because geared drivetrains have historically lacked sufficient reliability in harsh marine environments with limited maintenance accessibility.
What recent corporate restructuring has affected the wind turbine generator and power electronics supply chain?
In December 2025, Siemens Gamesa finalized the sale of its Gamesa Electric power electronics division, including wind converter product lines, to ABB.
How significant is generator innovation in supporting continued progress toward higher-capacity offshore turbine platforms?
Continued generator scaling has directly enabled record offshore turbine capacity, with manufacturers including Goldwind demonstrating how generator technology innovation has kept pace with turbine platform ambitions.
Notable key players include Goldwind, Siemens Gamesa, GE Vernova, WEG, Enercon, and ABB.
Recent Developments
The wind turbine generator market continues to track the broader industry’s push toward larger, higher-capacity offshore platforms, with permanent magnet direct-drive technology proving central to enabling record-setting single-unit capacity milestones such as Goldwind’s 20 megawatt installation in China. That scaling trend has not been without tradeoffs, as larger direct-drive generators require substantially more permanent magnet material and more demanding mechanical structures, introducing genuine supply chain and manufacturing complexity that the industry continues to address. Recent power electronics consolidation activity further illustrates how the broader generator and converter supply chain continues to reshape itself around core technology strengths. Overall, the market is expected to grow due to continued offshore capacity scaling, growing permanent magnet adoption, and expanding international deployment of advanced generator technology.
