The energy transformation, in this paper has two faces: the efficiency of energy transformation in accordance with new discoveries and concepts and the maximal reduction of the negative impact on the environment. Taking into account these two aspects, this paper has in view, besides the traditional efficiency transformation processes, which precede the energy yielding under different forms, the irreversible transformation in the cycles of this installation. The theoretical part is based on the most recent research in the field, adapted to the local condition by using an appropriate mathematical model. This model attempts to print out the basic parameters, which accompany the process, and to provide a methodology for the analyses and interpretation of data. The analysis and interpretation of data is based on their comparison with similar data experimentally obtained during a long operation period in order to draw a conclusion regarding the proposed method and this accuracy. In parallel with the analysis of operation from an economic point of view, the influence of the process on the environment is also assessed. Thus, it is possible to compare the impact obtained through the methodology used with the data obtained by foreign researchers and with European standards.
