Claim Text:
1. A method of determining available electrical demand reserve at a facility remotely located from an electrical utility and having a communicative load-control switch (LCS) controlling an electrical load, the method comprising: sampling an electrical signal associated with the electrical load; determining a power usage of the electrical load based on the sampled data associated with the electrical load; storing in a memory device at the facility the power usage of the electrical load; determining at the facility a characteristic load profile of the electrical load based on the power usage of the electrical load, wherein determining a characteristic load profile includes calculating an average power usage for the electrical load over a predetermined number of days for the electrical load, for a predetermined time period T, the predetermined time period T starting at substantially the same time on each of the days comprises calculating an average power usage according to the equation: wherein Pc(t) is the characteristic power, m is the predetermined number of days, and t is a t th minute of a day n, and where t ranges from 0 to 1439; and determining at the facility an electrical demand reserve of the electrical load based on the determined characteristic load profile of the electrical load, wherein the electrical demand reserve is determined according to the equation: P
