The consumption tab is for time-series energy capture only. It allows users to specify parasitic energy use of the turbine such as component heating (blade heating is on the icing loss tab) and cooling. If the parasitic losses are included in the power curve then check the second check box to say that this is the power consumed by the turbine when offline only. Values are interpolted within the table. For values of temperature or velocity that are outside the limits of what is defined here, the nearest table values are used.
