[Problem] In conventional technology pertaining to demand target display devices, different time information was used for the power utility company and power consumers, resulting in a deviation from the demand values as recognized by the power consumers. [Solution] Proposed is a demand target display device that: comprises a dual scale for indicating time and power consumption; acquires an AC signal from the AC waveform of the AC power in the power supply line; generates time information on the basis of the acquired AC signal; transmits, at least from within the casing, the generated time information via radio waves; receives, in the casing, the time information transmitted via radio waves; shows the time, by way of the received time information, on the dual scale; acquires power consumption within a target demand value setting interval that contains the current time; and displays the relationship between the power consumption within the acquired interval and the target demand value set in the interval. |
