Abstract

Contribuindo para o debate acerca do aprimoramento da regulação do setor elétrico e para o melhor monitoramento financeiro das empresas reguladas, este trabalho analisa a sustentabilidade financeira das distribuidoras brasileiras de energia elétrica, usando informações de contabilidade, regulação e qualidade do serviço no período compreendido entre 2011 e 2014. Relaciona os resultados encontrados com o perfil dessas empresas quanto a porte, gestor estatal ou privado e grupo controlador. A ferramenta utilizada é a metodologia conhecida como análise por envoltória de dados (Data Envelopment Analysis – DEA). Os resultados mostraram que enquanto as empresas Elektro, Coelba, Mux Energia e CPFL Paulista são referências para as demais na maioria dos indicadores, a maior parte das distribuidoras apresentou um desempenho muito aquém. Verificou-se ainda que a escala de operação não é fator preponderante sobre o desempenho das empresas, e o resultado das empresas estaduais e do grupo Eletrobras em relação a qualquer outra empresa ou grupo foi classificado como crítico. This paper uses Data Envelopment Analysis (DEA) to evaluate the financial sustainability of the Brazilian electricity distributors taking into account financial statements, regulatory and quality information in the period between 2011 and 2014. It also analyzes characteristics of the companies such as size, private or state ownership and controlling group. The results show that while Elektro, Coelba, Mux Energia and CPFL Paulista are benchmarks in most indicators, the majority of the other firms presents poor performances when compared to them. The finds also indicate that whether scale is not an important financial performance determinant, state owned companies had critically worse indicators than their private peers.
