This paper analyzed a small-scale distributed cogeneration system, where the heat is supplied from the individual fuel cell equipped at each house and the electric power is provided by an electric network constructed on the houses. Each fuel cell is permitted to stop a day. Combination of once on-off patterns produce a similar pattern with the actual electric demand pattern. Energy utilization analysis has been made on this system using the energy consumption pattern measured for 37/26/11 residential houses. Evaluation of heat demand shows that the heat demand becomes larger than the heat provided from the system at the power-generation efficiency above 0.26. Total efficiency of the system exceeds that of the conventional system with the large-scale network and gas fired heat supply at the power-generation efficiency above 0.24.
