Brazil’s Power Grid Should Grow 9.1 Thousand MW in 2026, ANEEL Predicts

Brazil’s National Electric Energy Agency (ANEEL) expects Brazil’s power grid to gain 9,142 MW of installed capacity throughout 2026. In 2025, the sector had received 7,403.54 MW. Thus, the new volume represents a 23.4% increase.

Renewable Sources Dominate Brazil’s Power Grid in 2025

The data are part of the agency’s assessment of the expansion of the national generation fleet. In 2025, the sector received 136 new projects in commercial operation. Solar photovoltaic generation led the additions, with 63 new plants and 2,815.84 MW of capacity. Next, thermal plants added 15 units and 2,505.77 MW, while wind farms contributed 43 parks and 1,825.90 MW. Also, small hydroelectric plants added 199.34 MW across 11 projects, and a new hydroelectric plant contributed 50 MW to the system.

The ANEEL Generation Information System (SIGA) shows the position as of January 1. According to the survey, 84.63% of the country’s installed capacity already comes from renewable sources. However, that level is high by global standards, well above the average for countries such as the United States and China, which rely more heavily on fossil fuels.

Regional Distribution of Energy Investments in Brazil

In the geographic distribution of new projects in 2025, Rio de Janeiro led investments, with 1,681.07 MW in new installations. Next, Bahia added 1,371.59 MW, and Minas Gerais recorded 1,294.75 MW. At the current pace of expansion, Brazil’s centralized generation capacity already totals 215.9 GW at the start of 2026. Thus, the country is consolidating an investment trend that should keep attracting private capital to new wind, solar, and thermal plants in the coming years.

The accelerated growth of renewable generation reinforces Brazil’s power grid as one of the cleanest in the world. This evolution combines the country’s historical hydroelectric base with the rapid expansion of wind and solar energy in recent years.
