At a first time, an authorized directive is received by the utility provider to perform an operative action for shedding load of a power system by a minimum system load value on or before a second time. The utility provider may operate the SCADA/DCS system to assist in selecting a set of circuits wherein the total circuit load value of the selection is greater than or equal to the minimum system load value. In response to circuit selection, the SCADA/DCS system selects the corresponding set of circuit breakers and consults the circuit-subscriber notification database to select a set of subscribers corresponding to the selected set of circuits. A system, product, and/or device adapted for communicating data in response to circuit selection may then be accessed by the SCADA/DCS system to communicate to the selected set of subscribers an intention of performing the operative action on or before the second time. The utility provider may then program and/or operate the SCADA/DCS system to perform the operative action upon the selected set of circuit breakers on or before said second time.
