Increasing Energy Efficiency of Centralized Heating Supply System

Expected Results:

• implementation of new generating capacities;
• reduced pollutant emissions into the air;
• reduced heat losses;
• improved quality of heat supply services;
• optimized enterprise structure;
  better environmental condition of the city;
• higher energy efficiency and reliability of the (de)centralized heat supply system through reconstruction of production capacities.

Prospective projects:

• liquidation of 17 boiler houses aimed to cut down consumption of energy resources and natural gas and to reduce emissions of greenhouse gases (CO2 , NOx ), which will contribute to real improvement of the environmental situation and to conservation of natural resources;
• reconstruction of the highpressure steam boiler at TPP-3 aimed to reduce emissions of pollutants into the atmosphere (CO2 , NOx ) during generation of heat and electric energy.

The project provides for:

• construction of 2 cogeneration stations;
• liquidation of 12 boiler houses;
• reconstruction of the centralized heating supply system (disaggregation by installation of individual heat supply units in residential buildings);
• replacement of heat distribution networks;
• reconstruction of 58 boiler houses and 2 thermal power plants (TPPs) with replacement of 5 high-capacity boilers (at district boiler houses), 8 high-capacity boilers and 3 power-plant boilers (at TPP);
• installation of a turbogenerator (24 MW) at TPP-3;
• restoration of electric power generation at TPP-4 (from 24 to 244 MW depending on the feasibility study results);
• replacement of about 100 km of main heat networks;
• installation of 250 individual heating supply units, 1000 heat meters and pumps at heating units of residential buildings;
• implementation of frequency converters with replacement of pumping units at 8 objects of the centralized heat supply system;
• implementation of automation, dispatching and commercial electricity metering systems.

Current Status:

The project works are being carried out under the contract with the winners of the international tender.
