Figures from the Global Wind Energy Council (GWEC) in its annual Global Wind Market Development Supply Side Data Report show that a total of 28,395 wind turbines were installed worldwide by 23 different wind turbine manufacturers in 2025, or roughly one every 19 minutes.

This rate was up 23 per cent on the previous year, and a record 178 GW of wind turbine capacity was mechanically installed in 2025, 40 per cent higher than the previous year. Some 165 GW was connected to the grid, while 13 GW of new installations were not yet commissioned.

Danish wind turbine manufacturer Vestas has the greatest number of cumulative installations and was the first turbine manufacturer to pass the 200+ GW milestone in 2025. Goldwind moved into second position in 2025 (163 GW), followed by Siemens Gamesa (148 GW) and GE Vernova (125 GW), while Envision became the latest manufacturer to join the ‘100+ GW’ club, reaching 103 GW in cumulative installations by the end of 2025.

“This impressive growth comes despite years of challenging business conditions and supply chain disruptions and is a testament of the wind sector’s growing importance as a source of reliable, homegrown renewable energy at a time of turmoil in international import-based oil and gas markets,” said Ben Backwell, CEO of GWEC.

The upward trend in wind turbine size continued in 2025, as the average turbine size surpassed 6 MW. Weighted globally, the average onshore wind turbine size in 2025 was 6,160 kW while the average offshore wind turbine size reached 10,312 kW.

Hybrid drive (medium-speed) wind turbines also continued to gain popularity last year, with the
