Direct and Indirect Measurement of Residential and Commercial CIC: Preliminary findings from South African Surveys

Interruptions in the supply of electricity to customers are inevitable but it is important to measure, monitor and minimize the costs incurred. In this paper it is shown that customer interruption costs (CIC) depend on a variety of factors. They include the type of country and locality in which the interruptions occur. Actual costs depend on the types of appliances that are interrupted and the sectors within which they are associated. Not all the methods of evaluation developed in a first world setting are appropriate everywhere. This paper describes pilot studies undertaken in South Africa to determine the characteristics of CICs in the residential and commercial sectors. The results are discussed and analyzed.
