Abstract. The article discusses the main problems associated with improving the quality and reliability of power supply to public utility consumers in the cities of Uzbekistan. Five main problems of power supply of cities are presented: 1. In connection with the reconstruction and modernization of all power supply systems of cities, the possibility of building complex electrical networks in the republic. 2. Investigation of power consumption modes of public utility consumers for the purpose of energy saving. 3. Based on field measurements, patented methods have been developed for calculating electrical loads of the same type of household consumers and total electrical loads at transformer substations (TS), distribution points (DP), main regional substations (MRS) of power supply of cities. 4. The necessity of calculating and applying reactive power compensation in urban electric networks has been substantiated. 5. Recommended measures to reduce electricity losses in utility power networks. Thus, as a result of solving the tasks, based on the reconstruction and modernization of electrical networks in all cities of Uzbekistan. the quality of electricity and the reliability of electricity supply to urban consumers are increasing, and electricity losses are decreasing, which meets the energy saving policy in the republic.
