\u00a0The article presents a study of the efficiency of operation of power supply systems of industrial enterprises. A feasibility study was carried out comparing 2 types of intrafactory power supply schemes: the scheme with the installation of one shop transformer and the second option with the installation of two transformers of lower capacity. As a result of the calculations, the optimal option with two transformers was determined and the amount of saved energy was calculated, as well as the payback period of capital investments. A comparative study of two types of intrafactory power supply schemes is presented, their advantages and disadvantages are revealed.<\/em><\/p>\n
