Consultancy for Evaluation of Costs related to Power Interruptions and Regulatory Implications 

START

OBJECTIVES AND METHODOLOGY

The project aimed to conduct studies of the costs related to the quality of the electricity distribution service, starting from international research on the topic, development of econometric models to assess the interruption costs and development of regulatory models. The results of the study are important to verify whether the limits currently established by Aneel are adequate. Once the objectives are achieved, it is possible to assess whether the regulation converges to the interests of society, whether the current quality is consistent with the costs involved and which actions, in the medium and long term , will be necessary to obtain the desired quality levels. 

MAIN RESULTS

  • Presentation of conceptual foundations and updated bibliographic research on the subject, covering the main methodologies mentioned;
  • Evaluation of the main studies published on the subject in Brazil and abroad;
  • Definition of the best methodology to be applied in Brazil to assess the cost of interruptions to consumers;
  • Definition of the electricity interruption cost for consumers using econometric models, for various scenarios;
  • Definition of the electricity interruption cost for consumers using the results of other surveys conducted in Brazil and abroad, adapting them to the Brazilian reality, for various scenarios;
  • Definition of interruption cost models (Consumer Cost Functions, Cost of Unsupported Energy and Combined Cost Models) by types of consumers and models for defining Composite Consumer Cost Functions;
  • Definition of cost functions related to improving the reliability of the distribution system;
  • Evaluation of the best incentive mechanism for distributors to reach the desired values.
