Abstract

Systems that monitor and control energy distribution manage energy distribution or use for Energy Service Providers and end-users. A system includes a publicly or privately accessible distributed network, a network access device, and a management device. The network access device communicates with the management device through the distributed network to control loads at a remote location. The method of monitoring and controlling energy distribution receives data at an on-line Site, processes an application program that evaluates load and market supply data, and initiates power curtailment requests or power curtailment events.

Claims

1. A method of monitoring and controlling energy distribution, comprising:

monitoring electrical load data from a plurality of distributed locations through a network access device and electric market supply data from a source through a publicly accessible distributed network comprised of a plurality of networks and gateways; and

receiving said electrical load data at an on-line Site when said network access device initiates communications at predetermined time intervals through said publicly accessible distributed network, said on-line Site processing said electrical load data and said market supply data and initiating at least one power curtailment request at one of said distributed locations based on said electrical load data and said market supply data.

2. The method of claim 1 further comprising sending at least one message selected from the group comprising an electronic mail message, a pager message, and a facsimile message.

3. The method of claim 1, further comprising initiating at least one of a visual and an audible alarm before initiating said at least one power curtailment request.

4. The method of claim 1, wherein said power curtailment request comprises at least one wireless message.

5. The method of claim 1, further comprising providing user'"'"'s with user definable reports.

6. The method of claim 1, further comprising interfacing a network access device to said publicly accessible distributed network automatically at programmable timed intervals.

7. The method of claim 6, wherein said network access device initiates said communications with a management device.

8. The method of claim 1, wherein said market supply data comprises market prices of electric power.

9. The method of claim 1, wherein said at least one power curtailment requests comprises a power curtailment event.

10. A system for monitoring and controlling energy distribution from at least one energy service provider, comprising:

a publicly accessible distributed network;

a network access device that interfaces power monitoring and power curtailment circuitry to said distributed network; and

a management device that supports interfaces to said power monitoring and said power curtailment circuitry, said management device located remotely from said network access device, and comprising a control device that interfaces said network access device through said publicly accessible distributed network, wherein said management device controls electrical loads at a remote location based in part on market prices of electricity.
