Factors Affecting the Development of a Residential Customer Damage Function

This paper presents the results of an investigation of the direct, short term impacts and costs incurred by residential electrical consumers resulting from local random supply interruptions. Costs are evaluated using the preparatory actions consumers predicted they would take, given a specified scenario of recurring interruptions in electric supply. These preparatory action cost estimates are then normalized with respect to each user´s actual consumption and estimated peak demand. The effect of dwelling type on normalized outage costs is presented. The paper illustrates the development of a residential sector customer damage function utilizing this data.
