The first three hydroelectric plants built by Cemig began life as a huge factory, producing Cemig were inaugurated before the end of the hydroelectric generation plants. 1950s. The Tronqueiras Plant started operating Works on the Mannesmann steel company in January 1955, the Itutinga Plant one month were begun in May 1952. Mannesmann had later, and the Salto Grande Plant in 1956.

The then Governor of Minas Gerais state, Juscelino Kubitschek, put in motion the first actions that made this dream a reality. He was a practical visionary – a man with his feet on the ground, but who could see far into the future – and he undertook a bold and ambitious plan, for a large-scale and wide-ranging program of modernization, diversification and expansion of industry in Minas Gerais state. And for this, Cemig was born.
