 change of the heat supply systems structure, including rational combination of system and element redundancy, equipment with automatic devices and measuring instruments in the frames of automated systems of dispatching control over normal and emergency regimes of operation thereof, transition to the independent pattern of heat loading connection (ventilation and air conditioning) and closed system of hot water supply:  combined operation of heat sources for mutual heat supply networks with optimization of their operation regimes;  reconstruction of combined heat-and-power plants, boiler rooms, heat supply networks and heat sources, thermal hydraulic regimes adjustment, enhancement of construction-and-assembly and repair works quality, timely performance of scheduled measures, equipment of consumers with stationary and mobile heat supply units as reserve and (or) emergency heat supply sources;  development of legislative base providing efficient interaction between heat producers, organizations transportation and distribution, as well as consumers under market conditions. performing its Prospected structure, as well as volumes of heat production and consumption for the stated period are aimed at maximal satisfac- tion of Russia's economy demands. They also take into account de- urbanization processes, which has already started, including shift of industrial production beyond the boundaries of urban areas and active development of individual low-rise housing, the share of which is planned to amount to 52-55% of all residential proper- ties to be commissioned. Low-rise housing, as a rule, will be pro- vided with individual heat generators, while high-rise buildings - with centralized (partly with decentralized) heat sources. The main increment of heat output in the centralized heat supply systems will be provided by thermal power plants, the share of which in the total volume of heat production in the centralized heat supply systems will grow from 44 to 49-50% by the end of the third phase of the Strategy implementation. Besides, the use of waste-heat utilization units and renewable heat sources on the basis of geothermal and solar energy and biomass will be increased. As a result, the share of boiler rooms in heat output in the centralized heat supply sys- tems will be reduced from 49 to 40% by the end of the third phase of the Strategy implementation.
