Abstract: Provided are a power control system, power control device, server device, and method for controlling a power control system in which the power control device can control load devices even when communication between the power control device and the server device is cut off, and which allow for timely discovery that communication has been cut off. A server device (20) extracts at least one of an elapsed time and remaining number of control instructions not acquired by a power control device (10) by polling and provides a warning when at least one of the elapsed time and the remaining number is at least a predetermined value. When the server device does not respond to polling, the power control device (10) creates a control instruction based on control guideline information and executes the control instruction.
