Pressure at WTGs Individual per WTG 1.165 kg/m³ 95.1 % 744.6 m 3.5 C 924.9 hpa The calculation is based on conversion of a wind statistic (wind climate for the region) through a terrain modeling (roughness, elevation and local obstacles) to wind distribution on the turbine position based on the WINDATLAS method (Risø/DTU), where the software package WAsP (Risø/DTU) is used for performing the calculations. The calculated wind distribution is converted to expected annual energy production (AEP) through the power curve and air density correction.

Productions are without wake losses. For further details, ask at the Danish Energy Agency for project report J.nr. 51171/00-0016 or see WindPRO manual chapter 3.5.2. The method is refined in EMD report "20 Detailed Case Studies comparing Project Design Calculations and actual Energy Productions for Wind Energy Projects worldwide", jan 2003. Use the table to evaluate if the given power curve is reasonable - if the check value are lower than -5%, the power curve probably is too optimistic due to uncertainty in power curve measurement.
