The site would consist of three two megawatt turbines, with tower heights of approximately 80 metres and rotor diameters of approximately 92 metres. These dimensions will provide a maximum height to blade tip of approximately 126 metres, typical in size of modern turbines and similar to those you may have seen at Avonmouth.

How the figures are calculated
1) Predicted Output
capacity of wind farm (MW) x capacity factor
x
hours per annum (8,760 hours)
=
predicted output (MW hours per annum)
‘Capacity factor’ is the % of the wind farm’s maximum output expected over a year. 100% would mean that the wind turbines were generating their maximum output all the time, a little like driving a car at maximum speed all the time. In reality, the wind is usually blowing and the wind turbines generate electricity most of the time, at a lesser proportion of their maximum possible output.
2) Households Supplied
predicted output
÷
average UK electricity consumption per household per annum
=
number of households electricity needs supplied
3) Carbon dioxide emissions avoided

carbon dioxide savings per kWH
