An appliance management device (106) is provided with a correlation calculation unit (114), a parameter selection unit (115), an estimation equation determination unit (116), and an estimation unit (117). The correlation calculation unit (114) calculates correlation indices which each indicate the strength of the correlation between past power consumption in a residence and one of a plurality of parameter candidates, which are candidates for parameters to be employed in a model equation for estimating power consumption. The parameter selection unit (115) compares the calculated correlation indices with a predetermined threshold value, and selects parameters strongly correlated with the past power consumption from among the parameter candidates on the basis of the comparison results. On the basis of a model equation which employs the selected parameters, the estimation equation determination unit (116) determines an estimation equation for estimating power consumption. The estimation unit (117) determines parameter values for the selected parameters, applies these parameter values to the determined estimation equation, and thereby estimates power consumption. |
