The article presents the rationale for the choice of the method of powering electrical equipment for rail electrified machines used in greenhouses (frame areas). The comparison of two power sources according to the criterion of minimum operating costs is given. The main operating costs of machines with cable and battery power supply methods are highlighted, and cost components are shown. An expression that allows you to make a choice between cable and battery power supply is obtained. The choice of the method of power supply depends on the length of the greenhouse row, which determines the length of the cable line, on the duration of use of the rail mobile electrified machine during the day, on the difference in energy consumption during the direct conversion of electric into mechanical energy and through a battery, on the cost of batteries and cable.
