Abstract: Reliability cost/worth analysis involves an assessment of the costs of providing reliable service and a separate quantification of the worth of having that service. Uninterrupted electric power supply is a desire of a customer, although it is not realistic. For interruption costs assessments to be specific, they should obtain information that is customer specific. The customer survey approach is based on the assumption that the customer is in the best position to estimate the losses resulting from a power interruption. This customer survey approach presents a method to quantify the loss of the customers into monetary terms, due to electric power interruption. the major contribution of this paper, using survey method it is not only possible to obtain absolute power interruption costs for different customers but also shows the variation in interruption costs with the variation in interruption duration for each type of customer. Hence, these cost calculations can be further be used for the evaluation of other cost worth indices which will be useful for the future/reinforcement options for the reliability worth.
