Selecting a proper capacity of the CHP unit is a complicated problem where energy usage pattern of end users and energy price structures must be considered. Thus; advanced computer simulations are used to predict the proper capacity of the unit; however; certain methods require expensive information such as part load performance of the unit and load profiles of end users. This paper suggests a simple method of predicting proper capacity by presenting analytical equations which calculate annual savings with different capacity of the CHP unit. These equations have merit which can be applied to various conditions by covering the energy usage patterns and energy price structures.
