The telecommunications sector is highly dependent on the continuous supply of electricity to ensure the functioning of its operations. In this context, TIM works to prioritize the use of renewable energy, reduce consumption in general and optimize management during operation, reducing greenhouse gas emissions.
Since 2021, 100% of TIM’s electricity has been drawn from renewable sources, through the procurement of energy on the Free Market, the acquisition of certificates of origin (I-RECs) and, above all, the Distributed Generation (DG) project, that has been fundamental in reducing the environmental impact of the Company’s activities. Energy management is also a priority on the operational front: efficiency in the use of energy increases resilience and ensures continuity of the essential telephone and internet services.
In 2025, more than 65% of the energy used by the Company was sourced from the DG project, reinforcing TIM’s commitment to best environmental practices and increasingly becoming a benchmark in the telecommunications sector. With a predominance of solar plants, TIM ended the year with 137 facilities in operation, distributed across 23 states and the Federal District.

1 As of 2023, the biogas and natural gas plants of the distributed generation project were reclassified to fuels, for alignment with the Group.
2 It considers captive market, free market, distributed generation project and the Sky Coverage project.
3 Conversion to GJ is based on the factors from the National Energy Balance. There was a 1% reduction in total energy consumption, in GJ, compared to 2024.
