NOTE: We have recently (Aug 2009) started monitoring the wind speed at each tower with identical anemometers at identical heights. Indications are that the Proven turbine is experiencing a much better wind resource from the South West quadrant which will influence any comparison of these figures. There may be as much as 40% more energy in the wind at the Proven site. Analysis carried out by Evance ISKRA see Details
