CPFL Energia S.A. (BOVESPA:CPFE3) and Equatorial Energia S.A. (BOVESPA:EQTL3) are the potential buyers most interested in Companhia Energética de Brasília - CEB (BOVESPA:CEBR5)'s power utility CEB Distribuição S.A. so far, sources say. The sale model was devised by the Banco Nacional de Desenvolvimento Econômico e Social and the auction is expected for this year. Other energy groups are reportedly also studying the asset.

Equatorial asked Santander, its financial advisor, to also evaluate CEEE, Valor learned. Sought for comment, CPFL said that “it is always looking for growth opportunities, constantly evaluating assets that appear in the market.” Equatorial declined to comment.
