Uma metodologia de análise de desempenho econômico dos serviços de atendimento emergencial ao consumidor de energia elétrica: estudo de caso do Ceará

Abstract

Interruptions in electrical supply system normally cause several economic damages both to supplier companies and to their customers which are hard to be estimated. The extension of these damages is a function of the frequency and duration of the blackout and it varies according to the consumer’s characteristics. In Brazil, electrical supplier companies are regulated by federal and state agencies on behalf of the consumers and their major challenge is to reduce breakdown time and consequent economic losses. This work presents the conception and application of a methodology to make the economic performance assessment of customer’s emergency attendance services, according to the parameters and standards set by the Federal Regulatory Agency (ANEEL) and focusing both the supplier and consumers costs related to system breakdown. The proposed methodology was applied to the case of a electrical distribution company in Ceara State, in the northeastern Brazil, to which an optimized operational management system (SAEDE System) was built. SAEDE System is a computational tool that was developed to optimize the dispatch and the staffing of the emergency attendance teams who are employed to repair electrical fails in the regional system. The proposed methodology was applied to search the benefits of investments derived from using SAEDE System in customer’s emergency attendance services of electrical supply Company in Ceara State. Main results of the study point out that the application of SAEDE System contributes to reduce both customer’s costs as well as company costs related to electrical system breakdown in the study area.
