The Global Wind Energy Council (GWEC) has released its annual Global Wind Market Development Supply-Side Data Report, comprehensively reviewing the installed capacity, enterprise rankings, regional layout and technological development trends of the global wind power industry in 2025.

Statistics show that the total mechanically installed wind power capacity worldwide reached 178 GW in 2025, a sharp year-on-year increase of 40%. Around 165 GW was connected to the grid, while the remaining 13 GW of installed projects have not yet been put into grid-connected operation.

A total of 28,395 new wind turbines were installed by global wind turbine manufacturers in 2025, rising by 23% year on year.

In 2025, 23 wind turbine OEMs completed installations across the globe, including 15 in the Asia-Pacific region, six in Europe and two in North America. Up to five manufacturers have exceeded 100 GW in cumulative installed capacity.

In terms of cumulative installed capacity rankings, Vestas remains the world’s top player and became the first turbine maker to surpass 200 GW with over 201 GW installed. Goldwind ranks second with 163 GW, followed by Siemens Gamesa at 148 GW and GE Vernova at 125 GW. Envision has also entered the 100 GW club with cumulative installed capacity hitting 103 GW by the end of 2025.

For newly added installed capacity in 2025, the world’s top five manufacturers are all Chinese enterprises, reflecting robust domestic demand in China’s wind power market. Goldwind recorded 29.7 GW new installations, Envision 21.8 GW, Windey 19.8 GW, Mingyang Smart Energy 18.6 GW and Sany Renewable Energy 15.1 GW.

Excluding the Chinese mainland market, the top five players in overseas new installations are Vestas (12.9 GW), Nordex Group (7.7 GW), GE Vernova (5.8 GW), Siemens Gamesa (5.4 GW) and Envision (4.2 GW).

In terms of global business expansion, Vestas maintains the widest overseas footprint with operations covering 36 countries in 2025. Nordex Group has presence in 24 countries, Goldwind in 23, Enercon in 22 and Siemens Gamesa in 21.

China installed 18,291 new wind turbines in 2025, accounting for 67% of the global total. Seven Chinese wind turbine manufacturers have started overseas business layout, yet their core operations are still concentrated in the domestic market.

China’s newly completed onshore and offshore wind power installed capacity exceeded 130 GW in 2025, of which 120 GW was commissioned. Domestic wind turbine suppliers hold a market share of 99.96% within China.

Although nine out of the world’s top 15 wind turbine manufacturers are Chinese, 93.4% of their total installed capacity is still located in China.

Chinese manufacturers achieved 9.319 GW of installed capacity overseas in 2025. In terms of regional distribution, 57% was in Asia excluding China, 16% in the Middle East, 12% in Africa, 8% in South America, 5% in Europe and 2% in Oceania.

Key Regional Market Performance

European Market

3,504 new wind turbines were installed in Europe in 2025, taking up 12.3% of the global volume. Supported by local industrial advantages, wind turbine suppliers from Denmark, Germany, Spain and other European countries occupy 94.5% of the regional market, up 2.5% year on year.

Benefiting from strong performance in Germany and Turkey, Nordex Group took the first place in annual installations across Europe. Within the EU, Vestas, Nordex Group, Siemens Gamesa, Enercon and GE Vernova remain the top five suppliers. Chinese manufacturers supplied 446 MW of wind turbines to Europe in 2025, including 278 MW for the EU 27 member states.

U.S. Market

A total of 2,289 new turbines were installed in the United States, accounting for 8% of the global total. GE Vernova and Vestas continue to dominate the local market with a combined market share of 93%.

Unit Upgrade & Technology Development Trends

The trend toward larger-capacity wind turbines continues to accelerate, with the global average turbine capacity exceeding 6 MW in 2025. The global weighted average capacity of onshore wind turbines reached 6,160 kW, while that of offshore wind turbines stood at 10,312 kW.

The pattern of transmission technology routes has gradually taken shape. The market share of medium-speed hybrid drive turbines rose steadily from 29% to 37% year on year. Direct-drive turbines accounted for 4.4% of the market in 2025, down 4.3% compared with the previous year.
