<p>A smart controller (102) receives, from an EMS (70), control information as charge information that indicates electricity prices determined in accordance with a power supply of an electric power system (60) and an electric power demand of a consumer group. The smart controller (102) compares the electricity prices with a charge threshold value in a correspondence relationship between a predetermined operation mode and the charge threshold value, thereby determining the operation mode of an illumination (110), an air conditioning device (112), and a heat storage device (114) as loads so as to be an operation mode in which power consumption is reduced as the electricity prices becomes higher, and thus controlling the illumination (110), the air conditioning device (112), and the heat storage device (114) as the load.</p> |
