The “Senvion Energy Monitor (SEM)” mobile app offers customers who have purchased a Senvion wind turbine or own shares in a wind turbine a way to view a status summary of their wind tur-bine(s). The app can be used by wind farm operators as well as operators of single wind turbines. To keep the amount of information at a manageable level, it does not display all of the data availa-ble from a WTG but rather a small selection that, based on current knowledge, is of interest to cus-tomers. The data displayed is from wind turbines only, Meteo or grid stations cannot presently be shown.
