This list also includes the most powerful onshore wind turbines, although they are relatively small compared to the largest offshore ones. As of June 2024, the most powerful wind turbine in operation is the world's first 18MW semi-direct drive offshore wind turbine, developed by Dongfang Electric Corporation. [1] In October 2024, Dongfang ...
Offshore wind turbines are built up to 8 MW today and have a blade length up to 80 meters (260 ft). Designs with 10 to 12 MW were in preparation in 2018, [45] and a "15 MW+" prototype with three 118-metre (387 ft) blades is planned to be constructed in 2022. [needs update] [46] The average hub height of horizontal axis wind turbines is 90 ...
Enercon E-126 wind turbine. The Enercon E-126 [1] is an onshore [2] [3] wind turbine model manufactured by the German company Enercon.With a hub height of 135 m (443 ft), rotor diameter of 126 m (413 ft) and a total height of 198 m (650 ft), the turbine can generate up to 7.58 megawatts of power, making it the largest wind turbine in the world (by nameplate capacity) for several years, until ...

The power law is often used in wind power assessments [4] [5] where wind speeds at the height of a turbine ( 50 metres) must be estimated from near surface wind observations (~10 metres), or where wind speed data at various heights must be adjusted to a standard height [6] prior to use. Wind profiles are generated and used in a number of ...
In common usage, wind gradient, more specifically wind speed gradient [1] or wind velocity gradient, [2] or alternatively shear wind, [3] is the vertical component of the gradient of the mean horizontal wind speed in the lower atmosphere. [4] It is the rate of increase of wind strength with unit increase in height above ground level.

In wind vertical profile such the log wind profile, the roughness length (with dimension of length and SI unit of metres) is equivalent to the height at which the wind speed theoretically becomes zero in the absence of wind-slowing obstacles and under neutral conditions. In reality, the wind at this height no longer follows a logarithm.
