CEMIG Deploys Huawei 450 MHz LTE Technology to Strengthen Brazil’s Power Grid
New Telecommunications Infrastructure Supports Wider Coverage and Grid Automation
BELO HORIZONTE, Brazil — Huawei has announced a strategic collaboration with Brazilian energy utility CEMIG to accelerate the digital transformation of the country’s electricity grid through the deployment of a 450 MHz private LTE network.
According to Huawei, the initiative is designed to strengthen energy telecommunications systems, improve communication coverage and support automated grid operations across the state of Minas Gerais.
CEMIG is one of Brazil’s largest integrated electricity companies, operating across power generation, transmission, distribution and energy commercialisation sectors.
The company supplies electricity to more than nine million customers across 774 municipalities in Minas Gerais through one of the country’s most extensive power grid networks.
CEMIG Network and Telecommunications Project Manager Sandro Bernardes said the company is currently carrying out the largest investment programme in its operational history.
According to him, the initiative includes expanding substations, increasing grid capacity and modernising operations to meet growing energy demand.
However, the rapid expansion of the electrical system also created new challenges for the company’s telecommunications infrastructure.
“We realised that our telecommunications systems needed to evolve alongside the growth of the power grid to ensure reliable and secure connectivity across all facilities,” he said.
As part of efforts to strengthen its infrastructure, CEMIG selected Huawei as its technology partner after the company won a public bidding process based on technical capabilities and compliance with energy sector requirements.
Through Huawei’s Electric Power eLTE Private Network Solution, CEMIG will operate a high-capacity telecommunications network covering the entire state of Minas Gerais and centrally managed through the company’s operational control centres.
According to CEMIG, the deployment of a private LTE network not only improves operational efficiency but also supports asset modernisation and strengthens system safety.
The company added that reliable telecommunications infrastructure is essential for ensuring effective and secure automation of power grid operations.
As part of its digital transformation strategy, CEMIG selected the 450 MHz frequency operating under the 3GPP standard.
According to the company, the frequency provides wider coverage, high reliability and the ability to support large-scale connectivity at lower operational costs.
The technology is also widely adopted in the global energy sector due to its suitability for utility operations covering urban, industrial and rural environments.
Huawei said the private LTE solution is expected to improve grid resilience, accelerate system automation and strengthen real-time energy monitoring capabilities.
The latest development reflects broader efforts within the global energy industry to accelerate digital technology adoption in order to build more efficient, stable and resilient energy infrastructure systems.
