Abstract

POWER-DEMAND CONTROL APPARATUS AND METHOD Abstract of the Disclosure 5 According to a power-demand control apparatus of the present invention, the real power consumption PWR is a consumption of power supplied from the outside by an electric-load group 200 of a customer from the start of the control-interval period T until the current time. 10 A consumption of power supplied from the outside during the control-interval period is predicted based on the measured real power consumption PWR. The predicted power consumption PWp is compared with the target power consumption PWT. A startup instruction is 15 output to an additional-startup-apparatus if there is a margin between the predicted power consumption PWp and the target power consumption PWT, and the predicted power consumption PWp is lower than the target power consumption. The additional-startup-apparatus is the 20 standby apparatus capable of being started by using the margin power PW . M Figure 1 31
