Modelling of a complex district heating system by increasing the energy  system’s efficiency and by reducing emissions through the implementation of  new and low carbon technologies is presented. One of these technologies is  cogeneration which is used to increase energy efficiency and to reduce  carbon dioxide emissions. Presented model uses linear programming as a basis  for mathematical modelling of the energy system. The mathematical  calculation is set pragmatically, so it can be efficiently and reliably used  to assess the impact of most important parameters on the efficiency of the  regional energy system. The model analyses the effects of integration of  cogeneration into the existing energy system using a given goal function.  The basic criterion is set to be the reduction of environmental impact. The  model is successfully tested on the complex district heating system with the  power of about 600 MW.
