Abstract

A method of communicating utility usage data is provided. In one embodiment, the method comprises transmitting real-time utility usage data from a plurality of utility meters, receiving the real-time utility usage data from the plurality of utility meters, storing the real-time utility usage data in a memory, storing address information of the plurality of utility meters in memory, receiving requests from a plurality of utility users for real-time utility usage information and wherein the requests traverse a communication path that includes the Internet, processing the utility usage data of the utility users to provide the real-time utility usage information for each utility user, and transmitting the real-time utility usage information to the utility users over a communication path that includes the Internet.

Claims

1. A method of communicating utility usage data, comprising:

transmitting real-time utility usage data from a plurality of utility meters;

receiving the real-time utility usage data from each of the plurality of utility meters via a communication path that includes a medium voltage power line;

storing the real-time utility usage data in a memory;

storing address information of the plurality of utility meters in memory;

receiving requests from a plurality of utility users for real-time utility usage information and wherein the requests traverse a communication path that includes the Internet;

processing the utility usage data of the utility users to provide the real-time utility usage information for each utility user; and

transmitting the real-time utility usage information to the utility users over a communication path that includes the Internet.

2. The method of claim 1, further comprising transmitting a request for utility usage data to the utility meters of the utility users in response to receiving the requests.

3. The method of claim 2, wherein said request for utility usage data traverses a medium voltage power line.

4. The method of claim 2, wherein said request for utility usage data traverses the Internet and a medium voltage power line.

5. The method of claim 1, further comprising storing information of the plurality of utility users in memory.

6. The method of claim 1, wherein the utility usage data comprises power usage data.

7. The method of claim 1, wherein the utility usage data comprises gas usage data.

8. The method of claim 1, wherein the utility usage data comprises water usage data.

9. The method of claim 1, wherein the real-time utility usage information requested includes real-time pricing information for the utility user.

10. The method of claim 1, wherein the utility usage information requested includes real-time power usage information of the utility user.

11. A method of communicating utility usage data;

comprising;

receiving real-time utility usage data from each of a plurality of utility meters via a communication path that includes a medium voltage power line;

storing the utility usage data in a memory;

receiving a request from a requester for utility usage information of a utility user, wherein the request traverses a communication path that includes the Internet;

processing the utility usage data of the utility user to provide the utility usage information; and

transmitting the utility usage information to the requester over a communication path that includes the Internet.

12. The method of claim 11, further comprising transmitting a request for utility usage data to the utility meter of the user in response to receiving the request.

13. The method of claim 12, wherein said request for utility usage data traverses the internet.

14. The method of claim 13, wherein said request for utility usage data traverses a medium voltage power line.

15. The method of claim 12, wherein said request for utility usage data traverses a medium voltage power line.

16. The method of claim 11, further comprising storing address information of the plurality of utility meters in memory.

17. The method of claim 16, further comprising receiving the address information via a communication path that includes a medium voltage power line.

18. The method of claim 11, wherein the utility usage data comprises power usage data.

19. The method of claim 11, wherein the utility usage data comprises gas usage data.

20. The method of claim 11, wherein the utility usage data comprises water usage data.

21. The method of claim 11, wherein the utility usage information requested includes real-time pricing information for the utility user.

22. The method of claim 11, wherein the utility usage information requested includes time of use pricing information for the utility user.

23. The method of claim 11, wherein the utility usage information requested includes critical peak pricing information for the utility user.

24. The method of claim 11, wherein the utility usage information requested includes real-time power usage information for the utility user.

25. The method of claim 11, further comprising storing user information and address information of a plurality of users of a power line communication system in memory.

26. The method of claim 11, further comprising

determining a power output to a power network;

and

processing the real-time utility usage data of the utility meters of the power network and the power output to the power network to determine the efficiency of the power network.

27. A communication system for communicating utility usage data provided by a plurality of utility meters, comprising:

a plurality of medium voltage communication nodes communicatively coupled to one or more medium voltage (MV) power lines, wherein each medium voltage communication node is communicatively coupled to at least one of the plurality of utility meters; and

a computer system communicatively coupled to the plurality of MV communication nodes via a communication path that includes a MV power line and wherein said computer system includes a memory;

wherein said computer system is configured to;

receive real-time utility usage data from the plurality of utility meters via at least one of the MV communication nodes;

store received real-time utility usage data in the memory;

receive a request from a utility user for real-time utility usage information of the user, wherein the request traverses a communication path that includes the Internet; and

in response to the request, transmit the real-time utility usage information to the user over a communication path that includes the Internet.

28. The system of claim 27, wherein each of said plurality of MV communications nodes is configured to provide broadband communication service to a plurality of users.

29. The system of claim 28, wherein said computer system is configured to store user information of the plurality of users provided broadband communication service by said plurality of MV communications nodes.

30. The system of claim 27, wherein said computer system is configured to transmit a request for utility usage data to the utility meter of the utility user in response to receiving the request from the utility user.

31. The system of claim 27, wherein the real-time utility usage information requested includes real-time pricing information for the utility user.

32. The system of claim 27, wherein the real-time utility usage information requested includes real-time power usage information for the utility user.
