This paper presents an assessment of the customer interruption costs using a macro economic methodology of Korean customers by cities and provinces. The customer interruption cost is considered a very useful index in quantifying reliability worth from a customer point of view. This paper reviews the methodology to evaluate the customer interruption costs and ratio to the average revenues per electric energy sold for public, service agriculture, fishery, mining, manufacturing and residential sectors by cities and provinces in Korea.

Reliability of electric power supply by power system becomes major issue as the electric power industry is recently being regulated. Also a change of environmental condition related to power supply reliability should be considered in the view of power supplier since the competition between energy-industries is strengthen. In other words, because customers may choose other energy source instead of electric power due to an expensive energy charge, enhancing recklessly the reliability of power supply might not be an essential strategy. So to effectively cope with this problem, it is necessary to perceive the reaction of customers against power supply reliability and interruption cost. This paper evaluates the annual interruption costs of customers by regional groups in Korea using a macro approach to cope with these internal and external environment. That is, the each ratio of customer's interruption costs to price of electric power charge is evaluated for public, service, agricultural, fishery, mining, manufactural, and residential consumption by every cities and provinces.
