The paper considers the problems of designing autonomous power supply systems using the renewable energy resources. The efficiency of using energy resources in conditions of growing prices for electricity brings significant saving of both energy and financial factors. The analyses show that the main losses of energy resources are the result of inefficient use, distribution and consumption of electrical energy. There has been stated one of the most important problems of energy saving: many existing consumers are located at a significant distance from centralized power supply systems. Today connecting such consumers to large power grids is economically inexpedient. These facilities are supplied from the stand-alone power plants. According to the program of energy saving and energy efficiency improvement of FGC UES, PJSC, reducing electricity consumption for auxiliary needs of transformer substations is one of the main mechanisms for the program implementation.
