Summary[edit]

Description
English: A wind generator at Junction 11 of the M4 motorway, at Greenpark industrial estate, near Reading, Berkshire, England. Construction finished in November 2005. The turbine supplies approx 1000 homes (up to 1,500 local homes and businesses).

The turbine on top of the 85 m (279 ft) tower is the German-made Enercon E-70. The three fibreglass blades are each 33 m (108 ft) long, rotating at 6 to 21 rpm depending on wind speed. Maximum power output of 2.05 MW is reached at a wind speed of 14 m/s (31 mph) then remains constant with increasing wind speed. The hub is kept facing into wind.

At a pre-determined high wind speed the blades cease rotation.
