7. The utility apparatus of claim 5, wherein the home area network is a ZigBee network in which devices communicate according to a ZigBee communications protocol.

8. The utility apparatus of claim 2, wherein each of the respective configuration data are stored and partitioned according to the apparatus to which the configuration data correspond.

9. The utility apparatus of claim 1, wherein the utility identification module is a secure hardware component.

10. A method, comprising:

determining, by a utility processing apparatus of a utility apparatus, that the utility processing apparatus requires configuration data to interact with at least one of a metrology apparatus associated with the utility processing apparatus and a network apparatus that is associated with the utility processing apparatus;

detecting, by the utility processing apparatus, a removable utility identification module that is in communication with the utility processing apparatus, the utility identification module storing configuration data required by the utility processing apparatus to interact with at least one of the metrology apparatus and the network apparatus;

receiving, by the utility processing apparatus and from the utility identification module, the configuration data; and

interacting, by the utility processing apparatus, with at least one of the metrology apparatus and the network apparatus using the configuration data.

11. The method of claim 10, wherein:

receiving the configuration data comprises;

receiving, from the removable utility identification module, encryption data specifying an encryption key that is used to transmit reporting data to a network management apparatus that manages a utility network to which the utility apparatus belongs; and

receiving, from the removable utility identification module, routing data that specifies one or more network devices that belong to a same mesh network as the utility apparatus and that are in communication with the utility apparatus; and

further comprising transmitting meter data that is encrypted with the encryption key to a selected network device specified by the routing data.

12. The method of claim 11, wherein receiving routing data further comprises:
