The global wind industry installed a record 178 GW of capacity in 2025 — a 40% increase on the previous year — as five turbine manufacturers each surpassed 100 GW in cumulative lifetime installations, according to new data published by the Global Wind Energy Council.
GWEC’s annual Global Wind Market Development Supply Side Data Report shows that 28,395 wind turbines were installed worldwide in 2025, up 23% year on year. Of the 178 GW mechanically installed, 165 GW was connected to the grid while 13 GW awaited commissioning at year end.
Vestas retained its position as the top manufacturer by cumulative installations, becoming the first turbine maker to exceed 200 GW lifetime. Goldwind ranked second at 163 GW, followed by Siemens Gamesa (148 GW) and GE Vernova (125 GW). Envision joined the group, reaching 103 GW by the end of 2025 — the fifth manufacturer to cross the 100 GW threshold.
For the first time, all five top suppliers by 2025 installed capacity were Chinese. Goldwind led with 29.7 GW, followed by Envision (21.8 GW), Windey (19.8 GW), Mingyang (18.6 GW) and SANY (15.1 GW). Chinese manufacturers installed 18,291 turbines in 2025, accounting for 67% of global market share — almost entirely in their home market, where they held a 99.96% domestic share across more than 130 GW of new capacity.
Outside mainland China, Western manufacturers continued to lead. Vestas topped the rankings with 12.9 GW installed across 36 countries, making it the most geographically diverse supplier globally. Nordex Group followed with 7.7 GW in 24 countries, taking the top spot in Europe on the back of strong performance in Germany and Türkiye. GE Vernova (5.8 GW), Siemens Gamesa (5.4 GW) and Envision (4.2 GW) completed the top five outside China.
In Europe, 3,504 turbines were installed in 2025, representing 12.3% of the global total. European manufacturers held a 94.5% share of the European market — 2.5 percentage points higher than the previous year. Chinese suppliers contributed 446 MW to European installations, of which 278 MW was in the EU-27. In the United States, 2,289 turbines were installed, with GE Vernova and Vestas jointly holding a 93% market share.
The average wind turbine size exceeded 6 MW for the first time in 2025. Onshore turbines averaged 6,160 kW while offshore units averaged 10,312 kW. Hybrid medium-speed drivetrains continued to gain ground, increasing their global market share from 29% to 37%.
“This impressive growth comes despite years of challenging business conditions and supply chain disruptions,” said Ben Backwell, CEO of GWEC. “With wind power meeting 9.5% of global electricity demand today, we see enormous potential for wind manufacturers from all regions to continue to expand and grow their operations across existing and emerging markets.”
Backwell called on governments to accelerate permitting and grid development to sustain the pace of expansion. The Supply Side Data Report is released annually to GWEC members and subscribers via its Global Market Intelligence platform.
