摘要： The cogeneration system includes: a cogeneration apparatus which generates electric power using supplied fuel gas and supplies the electric power and heat; a heat accumulator which accumulates the heat supplied by the cogeneration apparatus; a controller which controls at least start and stop of the cogeneration apparatus; and a display unit that displays a remaining power generation duration which is a length of time for which the cogeneration apparatus can continue power generation. The controller 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 is capable of accumulating and (b) a current accumulated heat amount that is the amount of heat currently accumulated in the heat accumulator, and causes the display unit to display the calculated remaining power generation duration.
