1. A control method for minimizing during a billing period the on-peak power demand of a residential electric utility customer having an AC line and a plurality of interruptible non-priority loads and non-interruptible priority loads comprising the steps of:

  • (a) defining a control point of desired power demand;

    (b) shedding non-priority loads to attempt to decrease demand below the control point;

    (c) providing predetermined sliding time windows;

    (d) determining average energy demand of the loads over a predetermined sliding time window; and

    (e) dynamically increasing said control point to a new control point when all non-priority loads have been shed and when the average power demand within the time window increases beyond said control point whereby the value of the new control point is related to the last-named average power demand.
