      The Brazilian electric sector, as well as in other countries, is one of the most important areas of the economy because it creates the infrastructure for the development of other sectors and providing relevant public utility service to society. Thus, this study investigated the effectiveness of economic-financial Brazilian companies from the utility power sector from the perspective of the investor, through data envelopment analysis (DEA). The sample comprised 34 companies of the Brazilian electric sector, listed on BM&FBOVESPA in the years 2010 and 2011.

One of the possible causes of the reduction in the number of efficient companies can be attributed to the slowdown of the Brazilian economy growth in 2011 compared to 2010. ; O setor elétrico brasileiro, assim como em outros países, é umas das áreas mais relevantes da economia, pois cria a infraestrutura para o desenvolvimento dos demais setores e presta relevante serviço de utilidade pública à sociedade.
