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.

Waste that becomes energy: Brazil’s landfill biogas market

Brazilian landfills are the main source of methane in the waste sector, and the country still wastes most of this gas. With the Fuel of the Future Law in force, ANP regulation published in 2026 and an estimated pipeline of R$ 8.5 billion in investments, landfill biogas has moved beyond the realm of promise to […]

Por que 2026 Marca a Virada entre Renováveis e Segurança Energética

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.

Energia Sustentável em 2026: O Brasil no Centro da Transição Energética Global

Sustainable Energy in 2026: Brazil at the Center of the Global Energy Transition

Brazil ended 2024 with 88.2% of its electrical matrix made up of renewable sources, according to EPE's 2025 National Energy Balance. In 2026, the country occupies a unique position in the global sustainable energy scenario: while consolidating one of the cleanest matrices in the world, it faces concrete challenges of scale, storage, financing and geopolitical climate pressure in the post-COP30 period. This article analyzes the current state of sustainable energy in Brazil, the most recent data on the sector, the ongoing growth vectors and the bottlenecks that still need to be overcome for the country to transform its potential into effective leadership in the global green economy.
