Abstract
A personal computer (PC) system determines a demand usage value at a predetermined time for a load powered by an electric power system. The computer system includes a database for storing energy usage values and time values; a PC software logging routine for acquiring the values of energy consumed from the electric power system by the load, for determining corresponding time values for times at which the energy was consumed by the load, and for storing the energy usage values and time values in the database; and a PC software calculation routine for retrieving a predetermined count plus one of pairs of those values from the database, with one of the time values corresponding thereto being about equal to the predetermined time. The calculation routine determines a first demand value from a pair of the energy usage values and a pair of the time values corresponding thereto, and also determines at least one second demand value from at least another pair of the energy usage values and at least another pair of the time values corresponding thereto. The calculation routine averages the first demand value with the at least one second demand value to determine the demand usage value which is determined over a time interval about equal to the predetermined count times a predetermined time interval.
