The results of a numerical experiment that obtained with using of the developed mathematical model of the operation of the power supply system of the greenhouse are presented. The list of input factors of the model included external factors: ambient temperature, length of daylight hours, wind speed, insolation, and factors that characterize the internal working conditions of the greenhouse.The values of external factors varied within the average daily values for the location of the greenhouse, the process parameters were determined taking into account the possible modes of operation of the greenhouse. The dependences between the amount of thermal energy consumed by the greenhouse, the energy consumption of the energy supply system, the gross energy consumption of the energy supply system, the utilization rate of gross energy and the levels of factors are shown. The results of the analysis of the obtained dependencies are presented.
