PURPOSE: To easily distribute wirings roundabout even when many power loads are controlled and to eliminate the concentration of a load regarding the control to one controller. CONSTITUTION: A sensor node 2 predicts the power consumption amount of the entire facility according to a pulse output from an integrating wattmeter 1, and outputs power warning information based on the prediction to a transmission line 5. Control nodes 3a to 3c control the power consumptions of power loads 4a to 4c corresponding to the control nodes according to the power warning information received via the line 5. |
