Co-generation systems and district heating and cooling have been applied to urban areas for achieving a low-carbon society. However, CO_2 emissions from operations division including commercial buildings are still on the increase. Hence research of micro grid is conducted as one of the countermeasures for achieving a low-carbon society. In case micro grid is introduced actually, it is facilitated by choosing a region where district heating and cooling was already applied. Thus in this report, a combined system composed of micro grid and district heating and cooling was considered. The combined system in this study interconnected 3 commercial-scale utility customers with different electric demands and thermal demands. Annual CO_2 emissions in each condition were minimized by using a numerical software GAMS/BARON.
