Abstract

A method is implemented in a computer infrastructure and includes receiving data defining a detected gas emission level of a power generation facility. The method also includes communicating the data defining the detected gas emission level to at least one subscriber device using one of Service Oriented Architecture (SOA) based communication and Session Initial Protocol (SIP) based communication.

Claims

1. A method implemented in a computer infrastructure, comprising:

receiving data defining a detected gas emission level of a power generation facility;

communicating the data defining the detected gas emission level to at least one subscriber device using one of Service Oriented Architecture (SOA) based communication and Session Initial Protocol (SIP) based communication;

comparing a predicted gas emission level to the detected gas emission level to determine whether the detected gas emission level is within a predetermined margin of error of the predicted gas emission level, wherein the predicted gas emission level is a forecast of gas emissions of the power generation facility for a future time period; and

transmitting a control signal to the power generation facility based on the determination that the detected gas emission level exceeds the predetermined margin of error,

wherein the control signal changes power output of the power generation facility to cause an actual gas emission level of the power generation facility to match the predicted gas emission level.

2. The method of claim 1, wherein:

the detected gas emission level comprises a greenhouse gas emission level; and

the power generation facility comprises an electricity generating plant producing the greenhouse gas.

3. The method of claim 1, wherein:

the one of SOA based communication and SIP based communication is SOA based communication;

the at least one subscriber device is subscribed to a greenhouse gas web service via a web server;

the detected gas emission level is provided by a sensor at the power generation facility which publishes the data to the web server; and

the web server communicates the data by notifying the at least one subscriber device.

4. The method of claim 3, wherein the at least one subscriber device comprises at least one of:

an internal subscriber that is internal relative to an edge gateway comprised in a communication network associated with the power generation facility; and

an external subscriber that is external relative to the edge gateway.

5. The method of claim 1, wherein:

the one of SOA based communication and SIP based communication is SIP based communication;

the at least one subscriber device is subscribed to a presence server;

the detected gas emission level is provided by a sensor at the power generation facility which publishes the data to a web server; and

the presence server communicates the data by publishing the data to the at least one subscriber device.

6. The method of claim 5, wherein the at least one subscriber device comprises at least one of:

an internal subscriber that is included in a domain comprised in a communication network associated with the power generation facility; and

an external subscriber that is external relative to the domain.

7. The method of claim 1, further comprising:

receiving the control signal from the at least one subscriber based on the at least one subscriber device processing the data defining the detected gas emission level; and

adjusting an amount of power generation of the power generation facility based on the control signal.

8. The method of claim 1, wherein the detecting and the communicating are performed in real time.

9. The method of claim 8, wherein the detecting and the communicating are repeated at one of:

a predefined time interval, and based on the detected gas emission level differing from a previous value by a predetermined amount.

10. The method of claim 1, further comprising:

predicting the predicted gas emission level at the power generation facility.

11. The method of claim 10, wherein:

the detected gas emission level exceeds the predicted gas emission level; and

the control signal causes the power generation facility to reduce the power output to reduce actual gas emissions.

12. The method of claim 1, further comprising:

determining the power output of the power generation facility;

detecting a second gas emission level at a second power generation facility;

determining a second power output of the second power generation facility; and

transmitting a first control signal to the power generation facility and a second control signal to the second power generation facility based on;

the detected gas emission level, the detected second gas emission level, the power output, and the second power output.

13. The method of claim 1, further comprising:

predicting the predicted gas emission level at the power generation facility; and

obtaining current and predicted weather data;

wherein the communicating comprises transmitting the detected gas emission level, the predicted gas emission level, the current weather, and the predicted weather to the at least one subscriber device.

14. The method of claim 13, wherein the predicted gas emission level and the predicted weather data are for a same time period.

15. The method of claim 1, wherein a service provider at least one of creates, maintains, deploys and supports the computer infrastructure.

16. The method of claim 1, wherein steps of claim 1 are provided by a service provider on a subscription, advertising, and/or fee basis.
