Afluente was created in 2009, after another company controlled by the Neoenergia Group underwent a spin-off. At that time, the company took over the assets related to the generation and transmission of Coelba. 

On the Brazilian Stock Exchange, the company has both common shares (AFTL3) and fractional shares (AFTL3F). 

A Afluente Transmissão de Energia Elétrica S.A – Afluente T – was established in 2009 with the aim of taking over the generation and transmission assets of the Electricity Company of the State of Bahia – Coelba, a company that was also part of the Neoenergia Group. 

Currently, Afluente T operates with nine transmission lines, with a total length of 450 kilometers. In addition, it has three substations: Tomba, located in the municipality of Feira de Santana; Brumado II, in the city of Brumado; and Itagibá, located in Itagibá, all in the State of Bahia. 

Together, the substations have an installed capacity of 600 MVA. Thus, Afluente Geração e Transmissão de Energia emerged as responsible for the generation and transmission activities, where the company's assets were segregated from Coelba.
