Short summary

In this study we aimed to use the spinner anemometer calibration and nacelle transfer function determined on a reference wind turbine to assess the power performance of a second, identical turbine. An experiment was set up with a met mast and spinner anemometer on each turbine. For each wind turbine, the nacelle power curve agreed with the corresponding power curve within 0.10 % of AEP for the reference wind turbine and within 0.38 % for the second wind turbine, for a mean wind speed of 8 m s⁻¹.
