History and Formation of CEMIG
Companhia Energética de Minas Gerais (CEMIG) was founded in 1952 in Belo Horizonte, the capital of Minas Gerais. The company was established by the state government to create a public utility capable of coordinating electricity generation and distribution, addressing the demands of an accelerated process of industrialization and urbanization.
In its early years, CEMIG focused on expanding its infrastructure, investing in distribution networks and new hydroelectric projects. This period was marked by technical and logistical challenges related to extending the power grid to remote and hard-to-reach regions.
Beginning in the 1990s, the company entered a cycle of modernization and expansion, growing its consumer base and diversifying its operations. In 1997, CEMIG launched its initial public offering (IPO) on the New York Stock Exchange (NYSE), securing access to capital for investments in new technologies and expansion initiatives.
Throughout its history, the company has executed large-scale projects, including the construction and operation of some of Brazil’s major hydroelectric plants. CEMIG also expanded its generation portfolio with investments in renewable energy sources such as wind and solar power.
Between 2020 and 2024, CEMIG accelerated investments in infrastructure modernization and increased the share of renewables in its generation mix. The period was also shaped by adjustments to Brazil’s regulatory framework and heightened volatility in energy prices, requiring greater operational efficiency and strategic management.
