Abstract: Electricity concessionaires give off high financial amounts annually in repairs to consumers that experience service unavailability. Availability of the energy supply is a major challenge because the distribution infrastructure is constantly affected by climatic, environmental, and social causes. To assist decision making in mitigating grid failures, this study aims to predict the number of incidences of electricity shortage for consumers. A predictive model was developed using predictive data analysis and conforms to a knowledge discovery process. A hybrid classifier was developed from the model, using both unsupervised and supervised methods. The experiments were carried out with real incidence and climatic data from four subsidiaries of an energy concessionaire. The results show the forecasting model's feasibility, which presented classification accuracy between 58.33% to 91.66%. The results show that peculiarities in terms of geographic location, energy demand, and climatic conditions make it difficult to use a generic prediction model.
