Abstract

The preferred embodiments described herein relate to enterprise energy automation. In one preferred embodiment, a method for enterprise energy automation is provided. In another preferred embodiment, a method for delivering ancillary services to an energy supply and delivery system by a group of buildings is provided. In yet another preferred embodiment, a method for integrating an energy automation system is provided. Other preferred embodiments are also provided.

Claims

1. A computerized method for enterprise energy automation, the method comprising, at a computer:

(a) monitoring data from an energy supply and delivery system;

(b) extracting data from a plurality of building automation systems in a group of buildings;

(c) determining an energy performance model for each of the plurality of building automation systems using the extracted data from the plurality of building automation systems, wherein each energy performance model comprises a speed of response to a load shifting strategy and a magnitude of load shifting available;

(d) using the energy performance model for each of the plurality of building automation systems to build a portfolio-wide energy performance model defining a flexibility of the portfolio of buildings on both a day-ahead and real-time basis;

(e) determining an optimum operating strategy for the plurality of building automation systems using the portfolio-wide energy performance model and pricing information received as a part of the monitored data from the energy supply and delivery system; and

(f) sending a bid to the energy supply and delivery system for an energy supply and delivery system product as a part of the determined optimum operating strategy.

2. The method of claim 1, wherein the data from the energy supply and delivery system and the data from the plurality building automation systems are received via the Internet.

3. The method of claim 1, wherein the data from the energy supply and delivery system and the data from the plurality building automation systems are received continuously.

4. The method of claim 1, wherein the data from the plurality building automation systems includes meter data.

5. The method of claim 1, wherein the data from the plurality building automation systems includes occupancy data.

6. The method of claim 1 further comprising receiving local weather data for the group of buildings and applying the local weather data to the energy performance model for each building as a part of the determination of the optimum operating strategy.

7. The method of claim 1, wherein the data in (a) comprises status of one or more of the following:

a transmission line, a generating plant, and a distribution system.

8. The method of claim 1 further comprising:

(g) receiving an acceptance of the bid from the energy supply and delivery system; and

(h) executing the determined optimum operating strategy.

9. The method of claim 8 further comprising:

(i) providing compensation for the one or more buildings.

10. The method of claim 9, wherein the compensation comprises a share of utility tariff demand savings.

11. The method of claim 9, wherein the compensation comprises a share of ESP demand charge savings.

12. The method of claim 9, wherein the compensation comprises utility interruptible program payments.

13. The method of claim 9, wherein the compensation comprises ISO demand response program payments.

14. The method of claim 9, wherein the compensation comprises capacity sales within ISO-sponsored markets.
