PROBLEM TO BE SOLVED: To provide an exhaust heat generator set including an inexpensive electric steam stop valve closing means, capable of rapidly and perfectly closing an electric vapor stop valve even in case where power for driving auxiliary machinery cannot be obtained from a host commercial power system cooperatively operated therewith by service interruption of the host commercial power system. SOLUTION: The exhaust heat generator set which includes a vapor generator 11, an electric vapor stop valve 16, a turbine generator 10, a condenser 14, and a medium circulation pump 15 and is cooperatively operated with the host power system comprises an electric vapor stop valve bypass passage L4 for bypassing the stop valve 16, and a bypass valve 20 provided in the bypass passage L4. In the event of service interruption in the host power system, working medium vapor 10 is guided to a turbine 13 of the turbine generator through the bypass valve 20 to drive a generator 18 thereof, closing operation of the stop valve 16 is performed with the power generated by the generator 18, and the bypass valve 20 is closed after the closing operation is completed.
