1. A system for adjusting component loads to increase or decrease energy usage of a total load to maintain power consumption below a predetermined level operative at sequential time intervals, wherein each component load is assigned to at least one of multiple types of add/shed or increase/decrease routines, each routine controlling the addition, partial increase, shedding or partial decrease of said components loads, said system comprising:

  • a power meter connected to measure the power usage of each component load; and

    processor means connected to the total load and connected to said power meter, said processor means determining how much and which of the component loads should be increased/decreased or add/shed to maintain power consumption below said predetermined level based on the add/shed or increase/decrease routine assigned to each load, said processor means adding, shedding, increasing and decreasing each load according to its assigned routine, and wherein said processor performs said addition, partial increase, partial decrease, or shedding of said components loads to accommodate said predetermined level at a given time interval.
