Provided are a utility interconnection system, an interconnection control device, and a utility interconnection method capable of not interrupting power supply during the restoration of power. The utility interconnection system interconnecting with a power system is provided with: a storage battery; a power conversion device for converting the power from the storage battery to an AC current; and an interconnection control device for supplying power from a commercial power supply to a load and supplying power from the power conversion device to the load when the commercial power supply has failed. When the commercial power supply is restored, the interconnection control device starts the power supply from the commercial power supply to the load and stops the power supply from the power conversion device to the load after the start of the power supply from the commercial power supply to the load.
