Abstract

According to an embodiment, a control device includes a detecting unit, a communication unit, and a control unit. The detecting unit detects that a power-supplied device is connected to a power supply line relaying supply of power. The communication unit receives consumer authentication information including consumer identification information for identifying a consumer from a communication device when it is detected that the power-supplied device is connected to the power supply line, transmits the consumer authentication information to a first server, receives power-supply-availability determination information representing whether supply of power to the power-supplied device is possible or not, from the first server, and transmits power measurement information representing power supplied to the power-supplied device through the power supply line and the consumer identification information to a second server. The control unit supplies power to the power-supplied device when the power-supply-availability determination information represents that supply of power is possible.
