A system for determining service outages and restorations includes an outage management server (OMS) that generates reports of outages and restoration information for metering endpoints. The outages may be caused by faults at various locations in the distribution network. The metering endpoint may include a transmitter having a battery backup that transmits the outage information upon a failure to detect a voltage at the endpoint. The transmission of the information may be filtered based on configurable criteria. The metering endpoints may also inform the OMS when power is restored.

What is claimed: 1. A system for assisting a utility in responding to a power outage, comprising: a plurality of metering points; a collector that communicates with each of the plurality of metering points to form a fixed wireless metering network, wherein said collector periodically communicates with each of said metering points to establish a communication performance rate for each metering point and wherein the collector sets a potential outage indication after a number of successive communication failures occur with a given metering point; and an outage management system that receives information from the fixed wireless metering network concerning power outage conditions to determine metering points affected by said outage conditions. 2. The system of claim 1, wherein said metering points collect and forward power outage information to said collector. 3. The system of claim 2, wherein said collector and said metering points perform filtering of said power outage information. 4. The system of claim 3, wherein filtering comprises at least one of: configurable delays at said metering points prior to transmitting said power outage information, configurable delays at said metering points prior to transmitting a restoration message, configurable options in said collector that allow data to be aggregated prior to communicating with said outage management system, and configurable options in said collector that allow communications to be suppressed during a large-scale outage. 5. The system of claim 2, wherein said metering points select a random transmit slot within a predetermined transmission period in which to transmit power outage information to the collector. 6. The system of claim 2, wherein said metering points and said collector are adapted to verify a presence of power by measuring a voltage. 7. The system of claim 2, wherein a subset of metering points affected by a power outage are identified, and wherein said subset of affected metering points are assigned to a corresponding subset of collectors for verification of power outage or power restoration. 8. The system of claim 2, wherein said collector is adapted to ping said metering points to determine an extent of a power outage, wherein said ping comprises one of: a ping of each metering point directly, a ping of metering points in a communication path to determine if said communication path is available, and a ping of metering points farthest from said collector along a communication path to validate all metering points in the communication path with one message. 9. The system of claim 2, wherein said collector communicates power restoration information to said outage management system and wherein said collector receives power restoration information from said metering points. 10. The system of claim 1, wherein said fixed wireless metering network comprises a mesh network that enables said metering points to change communication paths. 11. The system of claim 1, wherein the number of successive communication failures required to set the potential outage indication is determined based on the established communication performance rate between the collector and said given metering point. 12. A method for use in a fixed wireless metering network for determining power outage conditions in an electrical distribution network, wherein the fixed wireless metering network comprises at least one collector that communicates wirelessly with a plurality of metering points, the method comprising, at said at least one collector: periodically communicating with each of the metering points and establishing a communication performance rate for each metering point; generating an indication of a potential power outage at a given metering point when a rate of success of subsequent communications with the given metering point deviates from the established communication performance rate for that given metering point; and providing the indication to an operator of the electrical distribution network. 13. The method recited in claim 12, wherein said generating step further comprises: detecting a number of successive communication failures with the given metering point; and generating the indication of a potential power outage if the detected number of successive communication failures exceeds a predetermined number. 14. The method recited in claim 13, wherein the predetermined number is selected based on the established communication performance rate for the given metering point. 15. The method recited in claim 12, further comprising transmitting the indication of a potential power outage to an outage management system that is in communication with the fixed wireless metering network. 16. The method recited in claim 15, further comprising: delaying the transmission of the indication of a potential power outage for a configurable amount of time; and not transmitting the indication of a potential outage if successful communications with the given metering point resume within the configurable amount of time.
