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 a first set of devices during multiple periods of time to produce power consumption data, the first set of devices being located at the one or more service points;

    storing the power consumption data in a repository;

    determining that a control event is to occur during which a supply of electric power is to be reduced to at least the first set of devices;

    after storage of the power consumption data in the repository and prior to commencement of the control event, estimating, under an assumption that the control event is not to occur, power consumption behavior expected of at least the first set of devices during a future period of time based at least on the stored power consumption data, wherein the control event is expected to occur during the future period of time;

    determining, prior to commencement of the control event, energy savings expected to result from the control event based at least on the estimated power consumption behavior of the first set of devices to produce projected energy savings;

    determining, prior to commencement of the control event, amounts of electric power stored by a second set of devices located at the one or more service points to produce stored power data; and

    determining, prior to commencement of the control event, an amount of available operating reserve based on the projected energy savings and the stored power data.
