Abstract

See full text

The present invention pertains to a power monitoring device configured in such a manner as to make it as easy as possible to perform power monitoring, notification and control for customers in coordination with the power utilization rate of a utility grid. The power monitoring device is provided with: a target power setting unit that receives, from outside, information indicating the power utilization rate of a utility grid by time, and, with regard to time periods in which the power utilization rate is greater than a prescribed threshold value, reduces preset target power consumption levels, and sets target power consumption levels by time; and an assessment and control unit that obtains, from outside, the power usage of power-consuming devices, and performs control in order to save power for the power-consuming devices in time periods in which the obtained power usage exceeds the target power consumption level.
