Electric power consumer data analyzing method

An electric power consumer data analyzing method realized in the electric power market in which a plurality of electric power consumers purchase electric power from an electric power supplier, the method comprising:

• an electric power consumer data collection step of collecting data on electric energy consumption by the respective electric power consumer in a predetermined period;
• a consumed electric energy classification step of classifying total electric energy consumption by the electric power consumers in said period into m levels;
• a degree-of-load-contribution classification step of classifying degree of load contribution of the electric power consumers in consideration of at least load factors of the load factors which are ratios of average values of the consumed electric energy of the electric power consumers in said period to the maximum values of the consumed electric energy and uniformity coefficient which are ratios of sum totals of the maximum values of the consumed electric energy of the electric power consumers who belong to the same level of the consumed electric energy in said period into n levels;
• an electric power consumer classification step of dividing the respective electric power consumers into m×n number of classes based on the classification steps;
• and
• an outputting step of outputting a result obtained in the electric power consumer classification step to a display unit for displaying or a storage unit for storing the results.
