Zusammenfassung:	A cogeneration system allows users to easily know a remaining power generation duration and prepare for stop of power generation when the cogeneration system is in independent operation. The cogeneration system includes: a cogeneration apparatus which generates electric power using supplied fuel gas (151) and supplies the electric power and heat (102); a heat accumulator (103) which accumulates the heat supplied by the cogeneration apparatus (102); a controller (106) which controls at least start and stop of the cogeneration apparatus (102); and a display unit (104) that displays a remaining power generation duration which is a length of time for which the cogeneration apparatus (102) can continue power generation. The controller (106) further calculates the remaining power generation duration based on a remaining heat accumulation capacity which is a difference between (a) a maximum accumulable heat amount which is the amount of heat the heat accumulator (103) is capable of accumulating and (b) a current accumulated heat amount that is the amount of heat currently accumulated in the heat accumulator (103), and causes the display (104) unit to display the calculated remaining power generation duration.
