During the operation of the power supply system of buildings for the storage of agricultural products, heat supply stops are possible, which are necessary for the repair of equipment. This happens as a result of emergency situations when the entire power supply system is turned off. In this case, during the main storage period, the temperature in the mass of products will increase due to internal heat release of the stored juicy raw materials. At the same time, the temperature in the upper layers of the product in contact with the air in the upper zone will gradually decrease. Reducing the temperature, for example, of potatoes below +2оC will lead to product damage and losses. Therefore, it is necessary to implement a number of measures making it possible to ensure the safety of agricultural products during this period. This article offers a calculation of the economic efficiency of the measures carried out during the shutdown of the power supply system of potato storage facilities. When assessing the economic efficiency of measures, a complex indicator is used – the reduced costs, which includes the estimated cost, current expenses, the safety of juicy vegetable raw materials. Two variants of measures are proposed. According to the first option, the dublicate power supply system is excluded from the basic one, but the electricity consumption is added to increase the temperature of the mass of products before lowering the outdoor air temperature in case of a temporary shutdown of the potato storage power supply system. The second version of the calculation of technical and economic indicators assumes the inclusion of a reserve diesel power plant in the composition of structures instead of a duplicate power supply system. The results of comparing the reduced costs for two options of measures making it possible to ensure the safety of stored products in the event of disconnection of energy supply sources of storage facilities are obtained.
