en.Wedoany.com Reported - Recently, Brazilian telecom operator TIM expanded its self-owned renewable energy supply system and introduced artificial intelligence into communication network energy management. The company currently generates approximately 70% of its network electricity consumption through 136 solar, hydroelectric, and biogas plants distributed across 23 states and the Federal District of Brazil, providing power support for over 20,000 mobile communication antennas.
The focus of this initiative lies in two aspects: the operating costs of communication networks and energy stability. Mobile communication networks have wide coverage and a large number of base stations. Antennas, transmission equipment, computer rooms, and edge sites require long-term continuous power supply, and electricity expenses have long been a significant part of operators' network operating costs. TIM began promoting distributed generation in 2017, initially with only 5 plants in Minas Gerais serving about 1,200 antennas. Now, this system has expanded to a multi-regional energy portfolio nationwide, with an annual power generation of approximately 474 GWh, equivalent to the annual electricity consumption of a city with a population of about 770,000. For a market like Brazil, which has vast territory and significant regional differences in power conditions, operators combining renewable energy with communication site operations can reduce exposure to traditional power purchases and regional electricity price fluctuations, while also providing more stable long-term energy security for remote areas, cross-state networks, and high-load sites.
With the introduction of AI into energy management, TIM's energy-saving path has shifted from "expanding clean power sources" to "precisely controlling the actual consumption of each site."
Starting in 2025, TIM has deployed AI projects in energy bill and electricity consumption data analysis. By establishing expected consumption patterns for various operational units and comparing them with actual billing and consumption data, it identifies metering anomalies, power consumption deviations, and equipment failure risks. Energy waste in communication base stations often does not come solely from a single large device but is hidden in the details of air conditioning, backup power, rectifiers, batteries, transmission equipment, and site operational status. If the AI system can continuously identify abnormal patterns, it can help the O&M team quickly detect metering errors, inefficient equipment operation, or site energy consumption deviations, reducing losses from manual inspections and delayed troubleshooting. As 5G networks deepen coverage, data traffic grows, and edge computing nodes increase, operators will face continued upward pressure on energy consumption. Simply purchasing green electricity is no longer sufficient to address efficiency issues. Data-driven energy O&M will become an important tool for reducing costs in communication infrastructure.
TIM also supplements its energy portfolio through the free electricity market and international renewable energy certificates, and has claimed to operate with 100% renewable energy since 2021. This application of AI capabilities to energy management indicates that the operator's sustainable transformation has entered a phase emphasizing observability, predictability, and optimization. For the global telecommunications industry, mobile network energy efficiency has shifted from a corporate ESG project to an infrastructure competitiveness issue. Those who can achieve a better balance between coverage, capacity, energy efficiency, and O&M costs will find it easier to maintain cost advantages in the expansion of 5G, IoT, enterprise private networks, and AI edge applications.
The case of TIM Brazil also provides a replicable model for the Latin American communications market. Many Latin American countries face challenges such as electricity price volatility, regional power supply disparities, dispersed communication infrastructure, and investment pressure for network upgrades. By reducing costs through distributed renewable energy, AI energy consumption monitoring, and site-level O&M closed loops, operators can help enhance the long-term resilience of mobile networks. Future progress will focus on whether the AI energy management project can be expanded to more sites, whether anomaly identification can translate into actual energy-saving benefits, and whether the renewable energy supply system can continue to support the growth of 5G and future AI edge businesses.
