This present paper deals with exergoeconomic results of the Wind Turbine Power Plants (WTPPs) for the first time to our knowledge. Ratio of exergy loss rate to capital cost-exergy efficiency graph and correlation are presented. Monthly exergoeconomic results are also presented for the three turbines. Ratio of exergy loss rate to capital cost and ratio of energy loss rate to capital cost depending on the wind speed are studied. And also as meteorological variables temperature (density of air) and humidity effect on ratio of exergy loss rate to capital cost are discussed and the results are given by the table and graphs clearly. The paper describes an exergoeconomic evaluation of wind turbine power plant. The analysis of the field data demonstrates the proposed system is a viable option for wind turbine power plant (WTTP) installations. (C) 2012 Elsevier Ltd. All rights reserved.
