SYSTEM AND METHOD FOR ESTIMATING AND PROVIDING DISPATCHABLE OPERATING RESERVE ENERGY CAPACITY THROUGH USE OF ACTIVE LOAD MANAGEMENT
First Claim
1. A method for estimating operating reserve of a utility servicing one or more service points, the method comprising:
- determining amounts of electric power consumed by at least one device during at least one period of time to produce power consumption data, the at least one device being located at the one or more service points;
storing the power consumption data in a repository;
determining that a first control event is to occur during which a supply of electric power is to be reduced to the at least one device;
estimating, prior to commencement of the first control event and under an assumption that the first control event is not to occur, power consumption behavior expected of the at least one device during a first period of time based at least on the stored power consumption data, wherein the first control event is expected to occur during the first period of time;
determining, prior to commencement of the first control event, projected energy savings resulting from the first control event based at least on the estimated power consumption behavior of the at least one device; and
determining, prior to commencement of the first control event, an amount of available operating reserve based on the projected energy savings.

Abstract
A utility employs a method for estimating available operating reserve. Electric power consumption by at least one device serviced by the utility is determined during at least one period of time to produce power consumption data. The power consumption data is stored in a repository. A determination is made that a control event is to occur during which power is to be reduced to one or more devices. Prior to the control event and under an assumption that it is not to occur, power consumption behavior expected of the device(s) is estimated for a time period during which the control event is expected to occur based on the stored power consumption data. Additionally, prior to the control event, projected energy savings resulting from the control event are determined based on the devices'"'"' estimated power consumption behavior. An amount of available operating reserve is determined based on the projected energy savings.

20. A method for a first utility to acquire operating reserve from a second utility, the method comprising:
-
requesting operating reserve from the second utility sufficiently in advance of a transfer time at which the operating reserve will be needed so as to facilitate measurable and verifiable load-controlled generation of the operating reserve, wherein load-controlled generation of the operating reserve results from; remote measurement of power consumed by at least one device during at least one period of time prior to the request for operating reserve to produce power consumption data, the at least one device being located at one or more service points serviced by the second utility; storage of the power consumption data in a repository; determination that a control event is to commence at the transfer time, wherein a supply of electric power is to be reduced to the at least one device during the control event; estimation, prior to commencement of the control event and under an assumption that the control event is not to occur, of power consumption behavior expected of the at least one device during a time period after the transfer time based at least on the stored power consumption data; determination, prior to commencement of the control event, of projected energy savings resulting from the control event based at least on the estimated power consumption behavior of the at least one device; and determination, prior to commencement of the control event, of an amount of the operating reserve based on the projected energy savings; receiving an acknowledgment from the second utility indicating that the second utility will supply the operating reserve at the transfer time; and receiving at least some of the operating reserve from the second utility at the transfer time and for a period of time thereafter. - View Dependent Claims (21)

22. A utility that provides electrical service to one or more remotely located service points, each service point including at least one device that consumes power during operation thereof, the utility comprising:
-
a repository; and at least one processor coupled to the repository, the at least one processor operable to; determine amounts of electric power consumed by the at least one device during at least one period of time to produce power consumption data; store the power consumption data in the repository; determine that a control event is to occur during which a supply of electric power is to be reduced to the at least one device; estimate, prior to commencement of the control event and under an assumption that the control event is not to occur, power consumption behavior expected of the at least one device for a first period of time based at least on the stored power consumption data, wherein the control event is expected to occur during the first period of time; determine, prior to commencement of the control event, projected energy savings resulting from the control event based at least on the estimated power consumption behavior of the at least one device; and determine, prior to commencement of the control event, an amount of available operating reserve based on the projected energy savings. - View Dependent Claims (23, 24, 25)

26. A virtual utility operable to at least offer energy to one or more requesting utilities for use as operating reserve for the requesting utilities, the virtual utility comprising:
-
a repository; and at least one processor coupled to the repository, the at least one processor operable to; determine amounts of electric power consumed by at least one device during at least one period of time to produce power consumption data, the at least one device being located remotely from the processor; store the power consumption data in the repository; determine that a control event is to occur during which a supply of electric power is to be reduced to the at least one device; estimate, prior to commencement of the control event and under an assumption that the control event is not to occur, power consumption behavior expected of the at least one device during a first period of time based at least on the stored power consumption data, wherein the control event is expected to occur during the first period of time; determine, prior to commencement of the control event, projected energy savings resulting from the control event based at least on the estimated power consumption behavior of the at least one device; determine, prior to commencement of the control event, an amount of operating reserve based on the projected energy savings; and manage distribution of the amount of operating reserve to at least one of the requesting utilities subsequent to commencement of the control event. - View Dependent Claims (27)
