Photovoltaic power generation system (PV) and cogeneration system (CGS) are expected to being installed as environmentally benign distributed power sources. Many discussions about PV and CGS have so far focused on the individual performance of the energy saving and/or reduction of CO2 emission. This paper discusses the ability of PV system and CGS for reducing CO2 emission of the whole energy system. The results are summarized as follows. 1) When the capacity of the combined-cycle generator is reduced by the introduction of CGS in house, hotel and hospital, the electric power supply of other generators of higher CO2 emission decreases in addition to that of the combined-cycle generator. As a result, the effect of CO2 reduction of CGS could be evaluated as high value compared to the individual system point of view. 2) When the annual power supply of coal generator is restricted considering the reduction of total CO2 emission of the electric power system, the effect of CO2 reduction of PV and CGS introduced in office and shop is evaluated lower.
