6. The system of claim 5 , wherein the power status change is at least one of: a power outage and a power restoration.

7. The system of claim 5 , wherein the meter is scheduled to transmit first if it has a high number of hops from the mesh gate.

8. The system of claim 5 , wherein the meter is scheduled to transmit first if it is a leaf node in a mesh network.

9. The system of claim 5 , wherein the mesh gate is further configured to select an isolated outage reporting configuration or a major outage reporting configuration, wherein the major outage reporting configuration includes a longer aggregation window.

10. The system of claim 5 , wherein the mesh gate does not retransmit the composite notification message during an exclusion period.

11. A computer program stored in a non-transitory computer readable form for execution in a processor and a processor coupled memory to implement a method of transmitting a meter power status, the method comprising:

recognizing a power status change at a meter at a first time;

waiting a predetermined recognition period from the first time to a second time;

determining that the meter is not scheduled to transmit first;

waiting a predetermined time period from the second time to a third time to receive a notification message from at least one neighboring meter including a meter identifier of the at least one neighboring meter;

responsive to receiving the notification message from the neighboring meter, adding the meter identifier of the meter to the received notification message including the meter identifier of the at least one neighboring meter before retransmitting the received notification message to at least one other neighboring meter; and

retransmitting the received notification message during a random time period from the third time to a fourth time.

12. A method of transmitting a meter power status, comprising:

recognizing, by a meter, a power status change at the meter;

if the meter is scheduled to transmit first, transmitting, by the meter, a notification message from the meter to at least one neighboring meter towards a mesh gate, wherein the notification message includes a power status indicator and a meter identifier of the meter;

if the meter is not scheduled to transmit first, waiting, by the meter, a predetermined time period to receive a notification message from at least one neighboring meter including a meter identifier of the at least one neighboring meter;

responsive to receiving the notification message from the neighboring meter, adding, by the meter, the meter identifier of the meter to the received notification message including the meter identifier of the at least one neighboring meter before retransmitting the received notification message to at least one other neighboring meter;

aggregating, by a mesh gate, received meter identifiers into a composite notification message, the composite notification message including a power status indicator and at least one meter identifier;

transmitting, by the mesh gate, the composite notification message to a server over a wide area network; and

retransmitting, by the mesh gate, the composite notification message.

13. A computer program stored in a non-transitory computer readable form for execution in a processor and a processor coupled memory to implement a method transmitting a meter power status, the method comprising:
