The calculated wind distribution is converted to expected annual energy production (AP) through the power curve and air density correction.

Productions are without wake losses. For further details, ask at the Danish nergy Agency for project report J.nr. 1171/-1 or see manual chapter 3... The method is refined in MD report " Detailed Case tudies comparing Project Design Calculations and actual nergy Productions for ind nergy Projects worldwide", jan 3. Use the table to evaluate if the given power curve is reasonable - if the check value are lower than -%, the power curve probably is too optimistic due to uncertainty in power curve measurement.
