PROBLEM TO BE SOLVED: To provide an outage predicting device which outputs an alarm signal.SOLUTION: An outage time zone predicting device 8 predicts an electric power system outage time zone to which a first power generation device 2 in which a load frequency control is performed so as to be balanced a requirement and a supply of an electric power between loads 5-1 to 5-n, and that supplies the electric power to the load, and a second power generation device 4 that supplies the load by using a renewable energy, and a first storage battery 3 that charges a generated electric power of the second power generation device 4 are connected. On the basis of weather forecast information, the outage time zone predicting device outputs an alarm signal indicating a possibility of an electric outage when it is determined that a first total value of a first prediction value indicating a maximum fluctuation amount of the load and a second prediction value indicating the maximum fluctuation amount of the generated electric power of second power generating device in a future time zone exceeds a second total value of a third prediction value indicating an adjusting force of the first power generating device corresponding to the fluctuation of load and the fluctuation of power generation of the second power generation device and a forth prediction value indicating the adjusting force of the first storage battery corresponding to the fluctuation of load and the fluctuation of power generation of second power generation device.SELECTED DRAWING: Figure 1
