  7. Abstract:
  8. Rapid growing use of energy resources in recent decades, caused to focus on combined heat and power generation systems according to their high efficiencies. Energy efficiencies with these technologies will be up to 90 percent. Some benefits of Co-generation systems are their high efficiencies, omitting of transmission and distribution lossesin the electricity grid, fuel consumption reduction, moving to ward privatization,independent and decentralized production of electricity and heat, increase competition in the power generation and reduction theemission of greenhouse gases, particularly carbon dioxide. In This article theeconomicsof combined heat and power generator stobe installed incomplexwiththe electrical power of more than 1MW have been examined. In this regard, the overall potential of combined heat and power generation systems to be installed in residential areas and Co-generation legislation and facilities have been reviewed, at first. Next, the thermal and electrical load calculation of a typical building using eQUEST software have been done. Finally, a software developed that represent the best scenario for installation and operation of CHP systems according to economic indicators, the best CHP size among the CHP models on the market and its location in the complex, the best pipeline path, best diameter and insulation thickness for each pipe; number, location and the size of pumps that are required and auxiliary boiler size. The economic indicators that are simple payback period, net present value and internal rate of return based on the CHP life time, legislation guidelines, energy prices in Iran and the possibility of selling electricity to the grid, which can be compared with the current situation of the lack of CHP system, and note the necessity of using these systems.
