Exergy, energy and technical availability analysis are performed. The case study includes the actual system data taken from the system in Cesme, Izmir WTPP. General energy, exergy and other performance parameters are also presented. Investigated WTPP is Turkey's first installed (1998) wind plant (1.50. MW) located in Izmir. Exergy efficiency of the power plant found to be between 0% and 68.20%. The monthly average technical availabilities are 96.11%, 98.71%, 98.52% for turbine 1, turbine 2, and turbine 3, respectively. Furthermore, authors developed some correlations, which are capable of predicting the values of exergy efficiencies of the WTPP for different power factor value. © 2011 Elsevier Ltd.EnglishCesmeIzmir [Turkey]TurkeyAvailabilityElectric power factorPower plantsWind powerWind turbinesActual systemAvailability analysisEnergy and exergy efficiencyExergy efficienciesPerformance parametersPower factorsRenewable energiesSecond law analysisWind plantWind turbine powerenergy efficiencyexergypower plantrenewable resourcewind powerwind turbineExergyArticle10.1016/j.energy.2011.01.047
