The paper is devoted to the problems of exergetic cost determination. A brief description of theoretical fundamentals of exergetic cost determination and its application are presented.The applied method of calculations is based on the rules of determination of cumulative exergy consumption. The authors discussed within the paper the additional possibilities ensured by exergetic cost analysis in comparison with the direct exergy consumption analysis. The presented methodology is applied for the analysis of influence of operational parameters on exergetic cost indices of steam power plant. Results of calculations concern one of the modem Polish power plant. Basing on the obtained results the Authors formulated several conclusions that shown advantages of application of exergetic cost analyses.
