Transmissão assume papel central na transição energética brasileira e mobiliza R$ 79,1 bilhões em novas expansões

Transmission takes center stage in Brazil’s energy transition, driving R$ 79.1 billion in new expansion projects.

The new Transmission Expansion Program and Long-Term Expansion Plan (PET/PELP) for the first half of 2026 encompasses R$ 79.1 billion in National Interconnected System projects that have been recommended by planning studies but have not yet received authorization or gone to tender. The plan entails approximately 20,500 kilometers of new transmission lines and 81,900 MVA of substation capacity. More than just a project portfolio, the document demonstrates that transmission has assumed a strategic role in the expansion of the electric power sector: without an adequate grid, renewable generation cannot be fully integrated, new consumption centers face constraints, and maintaining system operational security becomes increasingly complex.

The New Model of Brazil’s Power Sector: Why 2026 Marks the Turning Point Between Renewables and Energy Security

Brazil reached 2026 with 88.2% of its electricity generated by renewable sources, one of the cleanest matrices on the planet. Paradoxically, the government has just held the largest thermal auction in the country's history, contracting 19 GW of power for R$64.5 billion to guarantee energy security until the next decade. This article analyzes why this apparent paradox is, in fact, the most important structural change in the national electricity sector: Brazil stopped being hydrodependent and started operating a multitechnology system, more complex, more expensive and, at the same time, more resilient.
