Results of a survey of failure mechanisms of wind turbine blades in India, observed by service companies, are presented. Surface erosion is the most often observed blade damage mechanism, followed by lightning strikes. Leading edge erosion can be observed even 1–2 years after wind turbine installation, while structural cracks are observed most often only 5–8 years after installation of the wind turbines. The most often emergency repair requests are connected with blade bolt replacement, followed by lightning strikes. Lightning strikes are registered relatively often, every 1–2 years, depending on climate. Lightning strikes are also most often observed in monsoon areas of India and are most common reason for the wind turbine downtimes.
