PROBLEM TO BE SOLVED: To provide a cogeneration system capable of attaining both control of heat release operation of a heat storage device in full storage and securing of hot water in suspension of water supply.SOLUTION: A cogeneration system is equipped with operation control means C which controls thermoelectric generation operation for operating a thermoelectric cogeneration device 1 to generate heat and electricity together and heat release operation for releasing hot water stored in a heat storage device 4. The cogeneration system is equipped with water supply suspension detection means 29 for detecting whether or not it is in a water supply suspension state in which water supply from a water supply source to the heat storage device 4 is cut off. The operation control means C, when the water supply suspension detection means 29 does not detect the water supply suspension state, if a heat storage amount in the heat storage device 4 reaches an upper limit heat storage amount during execution of the thermoelectric generation operation, executes the heat release operation while continuing execution of the thermoelectric generation operation, and when the water supply suspension state is detected, if the heat storage amount in the heat storage device 4 reaches the upper limit heat storage amount during execution of the thermoelectric generation operation, stops the thermoelectric generation operation without executing the heat release operation. |
