It is shown that a number of multidirectional internal and external factors have impact on financial results - profits (losses) of an enterprise. The Dupont model, used worldwide to control financial results of the enterprise, helps to reveal dependences of various indicators influencing economic profitability of the enterprise. Economic-mathematical model employed to control financial results of the power enterprise is constructed. The major factor influencing the enterprise’s profit is its production capability during a particular period of time, which in turn depends on the established electric power at the enterprise and a number of hours in the considered period. The second factor influencing the volume of gained profits is the rated capacity efficiency, which characterizes the loading level of the available capacities during considered period. The third factor defining profits of the power generating enterprise is the coefficient of power efficiency output. The fourth factor, included into the model, is the price of the power released in the wholesale market. The wholesale price of provided electricity varies depending upon working regimes of the enterprise - basic or peak modes. As a result, a model including all factors influencing the price of the provided power and profits of the enterprise was constructed. The constructed model helps to reveal reserves of the possible profits at methodological level. Moreover, the model is instrumental in controlling financial results of the enterprise by revealing factors, which have negative impact on the enterprise’s profits during a certain period. The constructed model helps to assess actions leading to the increase or reduction of indicators inherent to the model. Therefore, the developed model provides an opportunity to supervise financial results of a generating enterprise as a whole, of a separate station containing a number of generating blocks, and of a separate generating block.
