Survey, Evaluating and Calculating the Costs Caused by Electricity Interruption

Abstract

This paper presents results of an investigation of direct short-term impacts on industrial, commercial, and residential customers and costs incurred by local random electrical supply interruptions. The study used a direct survey in The Southern Power Corporation of the Electricity of Vietnam (EVNSPC) to collect customer assessments of electric service interruptions to analyze the costs. The variation in interruption cost with the characteristics of interruptions, such as duration, time of day, week of year, advanced warning, and reliability history, and with the characteristics of the users was also investigated. These results of surveys and interruption costs of customers are included in the paper.
