Abstract

A system and method that allows a consumer to monitor the electrical power usage in a residence is disclosed. The electrical use may be monitored at the service level, the circuit level, or at the group level. The electrical usage is communicated to a power monitoring system using a power line communications network (PLC). The monitored electrical usage can be accessed by both the utility supplying the electricity and by the consumer or owner of the residence.

Claims

1. A method comprising:

monitoring an electrical power usage of a plurality of electrical outlets at a residence using a power line communications (PLC) network;

determining a first electrical power usage of a first group of outlets of the plurality of electrical outlets;

determining a second electrical power usage of a second group of outlets of the plurality of electrical outlets; and

providing the monitored power usage including the first electrical power usage and the second electrical power usage on a web site where the web site is accessible to both an electrical utility and a customer of the electrical utility.

2. The method of claim 1 wherein the first group of outlets is associated with a residence and the second group of outlets is associated with a business.

3. A method, comprising:

monitoring a rate of electrical usage of a plurality of electrical outlets in a residence;

communicating a first rate of electrical usage from a first group of outlets of the plurality of electrical outlets to a power monitor system using a power line communications network; and

communicating a second rate of electrical usage from a second group of outlets of the plurality of electrical outlets to the power monitor system using the power line communications network.

4. The method of claim 3 wherein the monitored rate of electrical usage including the first rate of electrical usage and the second rate of electrical usage is accessible to both a utility supplying the electrical power and a customer of the utility.

5. The method of claim 3, further comprising:

summing the rate of electrical usage from the plurality of electrical outlets to generate a total rate of electrical usage for the residence;

summing the rate of electrical usage from the first group of outlets to generate the first rate of electrical usage in the residence; and

summing the rate of electrical usage from the second group of outlets to generate the second rate of electrical usage in the residence.

6. The method of claim 5, further comprising:

displaying the total rate of electrical usage from the plurality of electrical outlets of the residence;

displaying the first rate of electrical usage from the first group of outlets in the residence; and

displaying the second rate of electrical usage from the second group of outlets in the residence.

7. The method of claim 5 wherein the first group of outlets is associated with a residence.

8. The method of claim 5 wherein the second group of outlets is associated with a business.

9. The method of claim 5, further comprising:

accumulating the total rate of electrical usage from the plurality of electrical outlets of the residence over a time period;

accumulating the first rate of electrical usage from the first group of outlets in the residence over the time period;

accumulating the second rate of electrical usage from the second group of outlets in the residence over the time period;

displaying the accumulated total electrical usage from the plurality of electrical outlets for the residence for the time period;

displaying the accumulated first rate of electrical usage from the first group of outlets in the residence; and

displaying the accumulated second rate of electrical usage from the second group of outlets in the residence.

10. The method of claim 9 wherein the time period is one month.

11. A method, comprising:

monitoring a rate of electrical usage of a plurality of electrical circuits in a residence;

communicating a first rate of electrical usage from a first group of circuits of the plurality of electrical circuits to a power monitor system using a power line communications network; and

communicating a second rate of electrical usage from a second group of circuits of the plurality of electrical circuits to a power monitor system using a power line communications network.

12. The method of claim 11 wherein the monitored rate of electrical usage including the first rate of electrical usage and the second rate of electrical usage is accessible to both a utility supplying the electrical power and a consumer of the utility.

13. A power monitoring system, comprising:

a plurality of power monitors;

a power line communications network running on an electrical wiring of a residence where the power line communications network connects the plurality of power monitors;

a computer system configured to communicate with the plurality of power monitors using the power line communications network such that an electrical use of a plurality of electrical outlets including a first group of outlets and a second group of outlets in the residence is monitored.

14. The power monitoring system of claim 13 where the plurality of power monitors are distributed at each electrical outlet in the residence.

15. The power monitoring system of claim 13 where the plurality of power monitors are distributed on each electrical circuit in a breaker box feeding the residence.

16. The power monitoring system of claim 13 where the computer system is in the residence.

17. The power monitoring system of claim 16 where the computer system communicates with the utility using one of the following:

broadband over powerline, phone line, wireless link.

18. The power monitoring system of claim 16 where the monitored electrical use is available on a web page.
