The global wind industry reached a major milestone in 2025 as five wind turbine manufacturers surpassed 100 GW in cumulative installed capacity, highlighting the rapid expansion of renewable energy deployment worldwide, according to the latest data from the Global Wind Energy Council.
GWEC’s Global Wind Market Development Supply Side Data Report revealed that wind turbine original equipment manufacturers (OEMs) installed 28,395 new turbines globally in 2025, representing a 23 percent increase compared with the previous year.
A record 178 GW of wind turbine capacity was mechanically installed worldwide in 2025, marking a 40 percent rise year-on-year. Of this total, 165 GW was connected to the grid, while 13 GW of newly installed capacity had not yet been commissioned by the end of the year.
Vestas Leads Global Installed Capacity Rankings
Vestas retained its position as the world’s leading wind turbine manufacturer by cumulative installations and became the first company to exceed the 200 GW milestone in 2025, reaching more than 201 GW of installed capacity globally.
Goldwind moved into second position with 163 GW of cumulative installations, followed by Siemens Gamesa with 148 GW and GE Vernova with 125 GW.
Envision became the latest OEM to join the “100+ GW” category after reaching 103 GW in cumulative installed capacity by the end of 2025.
Ben Backwell, CEO of GWEC, said the industry’s growth demonstrates the strategic importance of wind energy amid ongoing volatility in international oil and gas markets.
According to GWEC, wind energy currently supplies 9.5 percent of global electricity demand, with substantial growth potential remaining across both mature and emerging markets.
Chinese OEMs Dominate 2025 Installations
For the first time, the world’s top five wind turbine suppliers by installed capacity in a single year were all Chinese companies, reflecting strong domestic demand growth in China.
Goldwind led annual installations in 2025 with 29.7 GW, followed by Envision with 21.8 GW, Windey with 19.8 GW, Mingyang with 18.6 GW and SANY with 15.1 GW.
Outside mainland China, Vestas remained the leading supplier with 12.9 GW of installations, ahead of Nordex Group at 7.7 GW, GE Vernova at 5.8 GW, Siemens Gamesa at 5.4 GW and Envision at 4.2 GW.
GWEC noted that both Western and Chinese manufacturers maintained dominant positions within their home markets despite increasing international expansion efforts.
Global Expansion and International Market Penetration
Vestas was identified as the world’s most globalized wind turbine supplier in 2025, recording installations across 36 countries.
Nordex Group followed with installations in 24 countries, while Goldwind operated in 23 countries, Enercon in 22 countries and Siemens Gamesa in 21 countries.
The report showed that 23 different wind turbine manufacturers installed turbines globally during 2025. Fifteen manufacturers were based in Asia Pacific, six in Europe and two in North America.
China Accounts for 67% of Global Turbine Installations
China remained the world’s largest wind market by a wide margin in 2025.
Chinese manufacturers installed 18,291 turbines during the year, accounting for 67 percent of global market share. More than 130 GW of new onshore and offshore wind capacity was mechanically installed in China, while 120 GW was commissioned during 2025.
Chinese OEMs secured a 99.96 percent share of their domestic market, underlining the strong dominance of local suppliers.
Although nine of the world’s top 15 turbine suppliers originated from China, 93.4 percent of Chinese OEMs’ global installations remained concentrated within their home market.
Chinese suppliers installed 9,319 MW outside China in 2025. Of these overseas installations, 57 percent were located in Asia excluding China, followed by the Middle East with 16 percent, Africa with 12 percent, South America with 8 percent, Europe with 5 percent and the Pacific region with 2 percent.
Europe and USA Continue Strong Wind Deployments
In Europe, 3,504 turbines were installed in 2025, accounting for 12.3 percent of the global market.
European suppliers led by Danish, German and Spanish manufacturers controlled 94.5 percent of the European market, improving by 2.5 percentage points compared with the previous year.
Nordex Group emerged as Europe’s leading supplier in 2025, supported by strong demand in Germany and Türkiye.
Within the European Union, Vestas, Nordex Group, Siemens Gamesa, Enercon and GE Vernova remained the top five turbine suppliers.
Chinese manufacturers supplied 446 MW of wind turbines across Europe in 2025, including 278 MW within the EU-27 market.
The United States installed 2,289 new wind turbines in 2025, representing an 8 percent share of the global market. GE Vernova and Vestas together controlled 93 percent of the US market during the year.
Turbine Sizes Continue to Increase
The trend toward larger wind turbines accelerated in 2025, with the global average turbine size surpassing 6 MW for the first time.
The weighted average onshore turbine size reached 6,160 kW globally, while average offshore turbine capacity climbed to 10,312 kW.
Hybrid drive, or medium-speed, wind turbines also gained market share during the year. The technology’s share of the global market increased to 37 percent in 2025 from 29 percent in the previous year.
When combined with conventional high-speed drive systems, geared-drive technologies represented 95.6 percent of the global market, up 4.3 percentage points year-on-year.
Direct-drive turbines accounted for 4.4 percent of the market in 2025, representing a 4.3 percentage point decline compared with the previous year.
