PROBLEM TO BE SOLVED: To provide an electro-thermal cogeneration system with a power storage device capable of improving efficiency of the overall system and reducing facility capacitance.SOLUTION: In an electro-thermal cogeneration system with a power storage device, power is supplied by using power generated by a power generation device and power stored in the power storage device together in a time zone where power consumption of a power load is equal to or more than specific output C1. In a time zone where the power consumption of the power load is less than or equal to specific output C2, power is supplied by commercial power and commercial power is stored in the power storage device. Therefore, in the electro-thermal cogeneration system, since commercial power is stored in the power storage device in a nighttime zone, stored commercial power can be utilized in peak hours, thereby reducing backup power for peak hours. |
