Due wind intermittence, the wind turbine annual energygeneration is far from theoretical one that arises from consideringthe nominal power of the turbine in the same period. That situationis quantified by the so called Capacity Factor (CF). It depends ofwind and turbine characteristics. The CF is determinant forstudies on feasibility and long term scenarios. Calculationprograms use the CF as an exogenous datum and, in some cases,as a constant in wide regions. That induces ?in some measurerudimentaryresults. On the other hand, nowadays there is someregistered evidence about changes in wind velocity, around theworld and also in Patagonia. Then, the necessity of an accuratecalculus for the CF over every specific region emerges for reducingerrors in mentioned studies of feasibility and long term scenarios.Another problem is that ?for CF calculus- it is necessary to usemean wind velocity at turbine height. That data is of very difficultobtaining.At present work we propose to calculate the CF for two regions inArgentina using wind data obtained from private individuals andfor various power curves of wind turbines. Results will becompared with others from regional data in use.We also propose to compare the results with others calculatedbased on wind data at 10 m (supplied by national weather service).That will permit quantify errors originated in turbulences andground roughness.
