The company Central Elétrica de Furnas was created on February 28, 1957, via Federal Decree 41,066 in order to build and operate Brazil's first large-scale hydroelectric plant, the Furnas Hydroelectric Plant, with an output of 1216 MW, on the Río Grande river. The company, which was based in Passos (MG), began operating in 1963.
