CIG

CEMIG’s formation took place amid rising electricity demand driven by the industrialization and urbanization of Minas Gerais. The initial objective was to establish a state-owned utility capable of planning and executing investments in power generation as well as transmission and distribution networks, contributing to the state’s overall energy integration.

The company’s portfolio includes electricity generation, transmission, and distribution, along with integrated energy solutions for large consumers and special-purpose projects. Its generation matrix is diversified, with a heavy concentration of hydroelectric power plants and a growing share of renewable sources such as wind and solar projects.

While its core operations are based in Minas Gerais, CEMIG also holds concessions and projects in other Brazilian states, ensuring a presence across multiple regions and reinforcing its significance in the national energy sector. The company serves millions of customers—including residential, commercial, and industrial users—solidifying its position as one of Brazil’s leading electric utilities.

Market factors influencing CEMIG’s operations include Brazilian power-sector regulation, technological developments in transmission and distribution networks, the global energy transition, and hydrological volatility affecting hydroelectric output.

The company competes with other regional concessionaires and private-sector firms engaged in power generation and energy trading.

CEMIG’s operational structure consists of approximately 5,500 employees, organized into divisions responsible for generation, transmission, and distribution activities. It maintains operational units and administrative centers throughout Minas Gerais and in other states where it holds concessions and strategic partnerships.

The company also maintains numerous subsidiaries and equity interests in industry projects and consortia, in addition to pursuing technological innovation and operational efficiency initiatives. CEMIG adopts sustainability and environmental-responsibility practices, including energy-efficiency programs and environmental-preservation initiatives.

CEMIG’s shares are traded on the New York Stock Exchange (NYSE) under the ticker CIG.

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.
