Gross energy output

The gross energy production is the energy production of the wind farm obtained by calculating the predicted free stream hub height wind speed distribution at each turbine location and the manufacturer’s supplied turbine power curve.  In defining the gross energy output, it is assumed that there are no wake interactions between the turbines and none of the loss factors listed in the remainder of the energy table are applied.  This result includes adjustments to the power curve to account for differences between the predicted long-term annual site air density and the air density to which the power curve is referenced.  It also includes the effect of the terrain on the flow.
