An energy management method is described that employs apparatus for automatically limiting the total instantaneous consumption of electrical energy in a residence having a plurality of energy consuming variable demand loads having different nominal current demands, said method including measuring the total current to the loads which are then in operation, and automatically interrupting the current, if any, to each of said loads in a predetermined sequence when the total current to the loads then in operation exceed the predetermined peak total current demand, until the total current is less than the predetermined peak total, the improvement whereby current consumption is maintained as high as possible without exceeding said predetermined peak demand, said improvement comprising: (A) establising a predetermined load shedding sequence which is independent of the nominal current demands of said loads; (B) measuring the actual consumption values of each load which is interrupted; (C) selecting from among those loads which have been interrupted, the loads which, according to said actual values and independent of said nominal values, can be restored without causing said total current to exceed predetermined peak demand; and (D) automatically restoring said selected loads to operation; the measurement of said actual consumption values enabling load restoration selections based thereon without modification of said energy management apparatus to account for variations in said nominal demands of said loads.
