Abstract: A method of activating an ice removal system of a wind turbine comprises: monitoring the output power of the wind turbine; monitoring an output from an ice sensor provided on the wind turbine indicative of an atmospheric icing condition; and activating the ice-removal system when the output power is below an expected output power and the output from the ice sensor indicates that an atmospheric icing condition has ended.
