Cogeneration systems (CGS) are penetrating power generation markets because of their potential of higher energy utilization efficiency with waste heat recovery process. Cost saving merit helps the promotion of CGS; however, this does not always lead to energy saving. We investigate the energy cost minimum operation of CGS using our performance test results of a micro gas turbine (μGT) as well as typical demand patterns of offices and hotels. We also calculate the fuel consumption associated with proposed modes of operation. It is found that we can achieve considerable cost saving (cost saving rate : office 37%, hotel 44%), but the fuel consumptions are increased at the same time. However, when the power generation efficiency of μGT is improved to 35%, we can achieve energy saving with the energy cost minimum operation.
