To address these challenges, Cemig conducted multiple rounds of technical evaluation and global use case research, ultimately selecting Huawei as its strategic partner to jointly deploy the first commercial 450 MHz private wireless network for the power sector in Latin America.

After field testing, the customer gained firsthand experience of the benefits delivered by the private wireless network, strengthening their confidence in distribution grid modernization and raising high expectations for the future energy transition: "Huawei submitted the best proposal during the bidding process, offering a solution that not only meets our current distribution grid modernization requirements but also scales for future renewable energy integration. Huawei has extensive experience in the energy industry. With Huawei's private network solution, Cemig will secure a high-quality private communications network.

1. Improved power supply reliabilityThe private wireless network lifted distribution terminal connectivity to 99% and communication reliability to 99.99%, significantly improving Cemig's power distribution service levels.

2. Mitigated business risksThe private wireless network can significantly improve line losses, SAIDI, and SAIFI, thereby helping Cemig avoid regulatory penalties.

3. Assured investment returnsThe private wireless network greatly enhances power services, ensuring Cemig meets ANEEL's regulatory requirements and secures favorable investment returns.

4. Expanded core production applicationsAs the foundational communications backbone for power production operations, the private wireless network delivers reliable last-mile connectivity for today's distribution automation.
