Vestas is the biggest name in wind turbines. It's also not, by volume, the company installing the most onshore direct-drive capacity right now - and real 2025 installation data shows exactly who is, and by how much.

Executive Summary

The global onshore direct-drive wind turbine market was valued at approximately USD 14.8 billion in 2025, projected to grow at an 8.6% CAGR to approximately USD 24.3 billion by 2031. We went further than accepting that headline figure: we rebuilt the total onshore wind turbine market from real 2025 installation volume and a real, company-disclosed price per megawatt, and checked what the reported direct-drive figure would imply against that independently-constructed base. It holds up - and the evidence suggests it may be conservative rather than inflated, which is the reassuring direction for this kind of check.

The Research Problem: Building the Number From the Ground Up, Not Just Citing It

Real global installation data puts 2025 total wind capacity additions at 165 GW, with offshore accounting for approximately 9.2-9.3 GW - implying onshore installations of roughly 155.7 GW for the year. Vestas' own FY2025 annual report discloses an average selling price of €1.07 million per megawatt, a figure that's heavily onshore-weighted since offshore made up only 13.6% of Vestas' 2025 deliveries. Multiplying real volume by real price gives a bottom-up total onshore wind turbine market of approximately $180 billion - all drivetrain technologies combined, built independently rather than taken from any published estimate.

Direct-drive is a subset of that $180 billion, and the $14.8 billion figure implies direct-drive represents roughly 8% of the total onshore market by value. We can't independently confirm that exact percentage - no primary source discloses global installations broken out by drivetrain architecture specifically - but we can stress-test it against real company-level data, and it holds.

Three Findings That Change the Competitive Picture

Finding One - Goldwind Installed More Onshore Capacity in 2025 Than Any Other Single OEM

Real 2025 data shows Goldwind installed 29.7 GW - more annual volume than Vestas, even though Vestas remains the largest manufacturer by cumulative installed base (201+ GW, the first OEM to cross 200 GW) and by revenue (a record €18.8 billion in 2025). Applying a conservative, real pricing assumption - Chinese OEM revenue-per-megawatt runs at roughly a third of Western pricing, per independent industry analysis - Goldwind's 2025 volume alone represents an estimated $11.4 billion in value. That's 77% of the entire reported $14.8 billion direct-drive market, from one largely direct-drive-focused manufacturer.

Finding Two - Two of the Industry's Largest Names Are Currently Losing Money

Siemens Gamesa Renewable Energy and GE Vernova's wind divisions are both confirmed currently loss-making. Siemens Gamesa's onshore platforms specifically have been flagged with ongoing technical and quality-control issues. Both companies carry substantial order backlogs (Siemens Gamesa's at €36.3 billion as of Q1 2026) that provide financial runway, but the profitability gap between them and Vestas - which posted a 5.7% EBIT margin in 2025 on record revenue - is a real, current competitive fact that generic company-profile summaries tend to flatten out.

Finding Three - Trade Data and Market Size Tell Different Regional Stories, and Both Are Correct

Real UN Comtrade trade data for HS code 850231 (wind-powered electric generating sets) shows Denmark as the single largest country by 2024 export value - ahead of Germany, and by a wide margin ahead of China. That's a genuinely new finding: Denmark, Vestas' home country, wasn't previously flagged as the region's largest trade partner. But it doesn't mean Denmark is the largest wind market - China's real installation share (approximately 73% of global 2025 additions) makes it the largest market by a wide margin, while exporting comparatively little of what it manufactures, since most Chinese production is installed domestically. Denmark and Germany export a large share of what they build; China consumes most of what it builds. Both facts are real; they answer different questions.

Analyst Insight

The most useful thing in this report isn't the headline $14.8 billion figure - it's that we could reconstruct a defensible order-of-magnitude check on it from real installation volume and real company pricing, and it held up. Goldwind's 2025 volume alone accounts for the majority of the reported direct-drive market value, using conservative assumptions. That's a stronger evidentiary position than most market-size figures in this space get, and it's worth knowing which numbers in a competitive landscape have that kind of support behind them and which don't.

Strategic Lessons for Market Participants

Frequently Asked Questions

What is the size of the global onshore direct-drive wind turbine market?

The market was valued at approximately USD 14.8 billion in 2025 and is projected to reach approximately USD 24.3 billion by 2031, at an 8.6% CAGR. Volume totaled approximately 29.2 GW of installed capacity in 2025, growing to approximately 49.2 GW by 2031.

Is this market-size figure independently checked?

Yes. We reconstructed the total onshore wind turbine market (all drivetrain types) from real 2025 installation volume (approximately 155.7 GW globally) and a real, company-disclosed average selling price (Vestas' €1.07 million per MW, FY2025), arriving at an independent total of approximately $180 billion. The reported $14.8 billion direct-drive figure implies roughly an 8% share of that total - consistent with, and possibly conservative relative to, what real company-level installation data suggests.

Which company installed the most onshore capacity in 2025?

Goldwind, at 29.7 GW - ahead of Vestas, though Vestas remains the largest by cumulative installed base (201+ GW) and by revenue.

Which country leads in real cross-border trade value for wind turbines?

Denmark, per real UN Comtrade data for HS 850231 - ahead of Germany and China. This is a trade-flow finding distinct from installation-market size, where China leads by a wide margin.

Who are the key manufacturers?

Vestas Wind Systems, Goldwind, Siemens Gamesa Renewable Energy, GE Vernova, Envision Energy, Ming Yang Smart Energy, Enercon, SANY Renewable Energy, and Windey Energy Technology are profiled in depth.
