Statistically-signifi cant tendencies of the regional heat supply system failures in Primorskiy Krai due to the condition of power, water and fuel supply systems and actions by subdivisions of «Heating Networks» have been revealed in this article. Assessments of the consequences, reflected by the increase of population-effecting heat supply failures ratio with the following turn-off time: «less than 1 hour», «1 to 6 hours», «6 to 10 hours» and «over 10 hours», are obtained thereto. In particular, the regional heat supply system may be characterized by the decrease of the number and severity of consequences of major breakdowns and increase of failures, resulting out of the chronically-poor condition of the heating system’s equipment, and improper interaction with the municipal power systems. According to the analysis results, the crisis of the central heating system can be characterized as administrative, which is contrary to the popular opinion on its physical nature. Preventive managerial measures aimed at increasing the reliability (quality and safety) of the heat supply are therefore highly recommended. Basing on the general principles of managing, the municipal power systems (including principles of calculation, expertise and approval of rates), it is proposed to apply the assessments, conclusions and recommendations to all  unicipal power supply systems.
