Abstract

Methods and systems provide power savings control based on financial compensation. The power reduction system is configured to automatically account for a desired or target power savings over a time period. The system compensates for previous or current decreases in power reduction for one or more loads to satisfy an aggregate target power savings by the end of a time period.

Claims

1. A system for controlling financial compensation based on reduced energy consumption in a power savings mode, the system comprising:

an alternating current source;

a load; and

a control unit connected with the load, the control unit operative to reduce an amount of power output to the load from the alternating current source and automatically alter the reduction of the amount of power output as a function of a power savings over a time period.

2. The system of claim 1 wherein the power savings comprises an energy cost savings.

3. The system of claim 1 wherein the power savings comprises kilowatts per hour.

4. The system of claim 1 wherein the power savings over a time period comprises a contractual savings over at least a month.

5. The system of claim 4 wherein the contractual savings is over at least a year.

6. The system of claim 1 wherein the control unit is operable to increase the reduction of the amount of power output in response to a reduction in the power savings.

7. The system of claim 1 wherein the load comprises a lighting load and the control unit comprises a lighting control unit.

8. The system of claim 1 wherein the control unit is operable to measure the amount of power output.

9. The system of claim 1 wherein the control unit comprises a processor connected with a plurality of power reduction units, the processor operable to cause at least one of the power reduction units to alter the reduction of the amount of power output as a function of the power savings over the time period based on a combined power savings by the plurality of power reduction units.

10. The system of claim 9 wherein the processor is operable to cause multiple of the power reduction units to increase respective reductions of amounts of power output in response to one of the power reduction units decreasing a respective reduction of power output.

11. A method for controlling financial compensation based on reduced energy consumption in a power savings mode, the method comprising:

(a) reducing an amount of power output to a load from an AC source; and

(b) altering the amount of power output as a function of an aggregate target power savings over a time period.

12. The method of claim 11 further comprising:

(c) inputting the aggregate target power savings as an energy cost savings for the time period;

wherein (b) comprises altering the amount so that an actual power savings over the time period is at or less than the aggregate target power savings.

13. The method of claim 11 further comprising:

(c) inputting an aggregate target power savings as a kilowatts per hour for the time period;

wherein (b) comprises altering the amount so that an actual power savings over the time period is at or less than the aggregate target power savings.

14. The method of claim 11 wherein the aggregate target power savings over a time period comprises a contractual savings over at least a month.

15. The method of claim 11 further comprising:

(c) detecting a decrease in the reduction of (a);

wherein (b) comprises decreasing the amount of power output as a function of both the decrease in the reduction of (a) and the aggregate target power savings.

16. The method of claim 15 wherein (a) comprises reducing the amount of power output to a lighting load.

17. The method of claim 11 further comprising:

(c) monitoring respective power savings for each of at least two power reduction units;

wherein (b) comprises compensating for a reduction in power savings by a first one of the at least two power reduction units with an increase in power savings by a second one of the at least two power reduction units.

18. The method of claim 17 wherein (b) comprises maintaining a total power savings provided by the at least two power reduction unites at any given time such that the aggregate target power savings is met at the end of the time period.

19. The method of claim 11 further comprising:

(c) establishing the aggregate target power savings with a contract; and

(d) entering the aggregate target power savings into a monitoring program wherein the monitoring program implements (a) and (b) automatically.

20. The method of claim 19 wherein (b) comprises providing for a greater power reduction over the time period than the aggregate target power savings;

and

further comprising;

(e) compensating for a later failure to meet the aggregate target power savings with any excess power savings.

21. A method for controlling financial compensation based on reduced energy consumption in a power savings mode, the method comprising:

(a) monitoring power reductions for each of a plurality of loads;

(b) calculating a total power reduction from the power reductions; and

(c) automatically altering power reductions for multiple of the plurality of loads in response to a decrease in the power reduction provided to one of the plurality of loads, the altering being as a function of a target power savings and the total power reduction.

22. The method of claim 21 wherein (c) comprises maintaining the total power reduction at a target power savings.

23. The method of claim 21 further comprising:

(d) calculating an increased power reduction to meet an aggregate target power savings by an end of a time period in response to the decrease in the power reduction.
