PROBLEM TO BE SOLVED: To deal with temporary increase of power consumption by providing means for controlling the total power consumption not to exceed a receivable power by reducing power consumption of predetermined apparatus in a shop when a detected total power consumption reaches a preset value within the range of receivable power. SOLUTION: A shop illuminator 1, a showcase illuminator 2, an air conditioner 3 and a low temperature apparatus 4 are connected with a power line 5 which is connected with a detector 6 for detecting total power consumption of the apparatus 1-4. The detector 6 is connected with a power controller 7 which is connected to transmit a control signal to each apparatus 1-4 through a shop illuminator controller 8, a showcase illuminator controller 9, an air conditioner controller 10 and a low temperature apparatus controller 11. During operation control through the power controller 7, a heat source machine for the illuminators 1, 2, the air conditioner and the low temperature apparatus is set sequentially in lower power state so that total power consumption falls within the receivable power. |
