  The present invention relates to a power usage monitoring system and a power usage monitoring method.

  In general, the electricity charge is calculated by the sum of the basic charge and the usage charge.

  Of these, for basic charges, in the case of normal business power, the demand power is measured in units of 30 minutes, and based on the demand power (maximum demand power) when demanding the most power throughout the year, The basic charge for the following year is determined.

  Therefore, if the above-mentioned maximum demand power can be kept low, it can lead to a reduction in the electricity bill and contribute to energy saving.

From such a viewpoint, conventionally, in order to suppress the maximum demand power, the demand power is constantly monitored, and when there is a possibility that the demand power exceeds a predetermined target value, the control target is forcibly controlled. A so-called demand control device for stopping the operation of the device is used (see, for example, Patent Document 1).
