An arrangement for controllably disconnecting a utility power service from a load includes a utility meter housing, a service switch, an energy storage device and a control circuit. The utility meter housing includes metrology circuitry configured to generate metering information regarding electrical power provided to the load. The service switch is configured to controllably interrupt a connection between the utility power service and the load, and has a controller. The control circuit is configured to cause the energy storage device to be connected to the controller responsive to a service disconnect command. The control circuit is further configured to cause a portion of the metrology circuit to be connected to the energy storage device and the meter power supply to be disconnected from the portion of the metrology circuit responsive to a power interruption detection signal.
