Ahsan Department of Electrical and Electronic Engineering Bangladesh University of Engineering and Technology, Dhaka-1000, Bangladesh Email: qahsan@eee.buet.ac.bd (Received on 27 Apr 2004, revised on 26 May 2004) Abstract Uninterrupted electric power supply is a desire of a customer of electricity, although it is not realistic. However, the electric power interruption may create a significant loss to a customer. This paper presents a methodology to quantify the loss of the residential and industrial customers, into monetary term, due to electric power interruption with a view to creating awareness among the customers and the utility of the actual amount of loss inflicted on the customers. Introduction Each electric power interruption incurs a loss to a customer. It is not realistic that a system would be completely uninterrupted one, but the frequency and duration of power interruption should be limited to an acceptable level. Generally, the utility requires more money to invest to improve its system reliability. The quantification of the effects of power interruption into monetary term can make a customer of the actual loss inflicted on him. This will also help the utility to justify higher investment to improve its system reliability. A list of publications relating to the theory and surveys concerned with determining the impacts and estimating the costs to customers of electrical service interruptions is presented in [1-2].
