Abstract: Electricity affordability for the low-income population is still a challenge in Brazil. In this paper, we propose specific affordability indicators to categorize the socio-economic complexity of each utility concession area, also aggregating current information on customers' non-payment, presenting an analysis and maps electricity affordability countrywide. The results show areas in regions North, Northeast, and Southeast, where electricity affordability is still a matter of concern, in spite of existing access. These findings indicate the need to continue implementing public policies that promote affordability and also suggest indicators for use in monitoring the performance and progress of such efforts Ver menos
