By Brazil Stock Guide – Brazil expanded its national power generation capacity by 6,564.81 megawatts (MW) between January and October 2025, according to the Relatório de Acompanhamento da Expansão da Oferta de Geração de Energia Elétrica (RALE) published by ANEEL, the country’s electricity regulator.
As reported by Agência iNFRA, the agency’s data show that 113 new power plants began operating during the first ten months of the year, confirming the steady growth of Brazil’s energy infrastructure. Thermoelectric generation led the expansion, adding 2,493.05 MW, followed by solar photovoltaic projects (2,277.82 MW) and wind farms (1,537.90 MW). Smaller additions included 11 small hydroelectric plants (199.3 MW), one large hydro plant (50 MW), and one micro hydro generator (6.7 MW).
In October alone, 19 new facilities came online, totaling 643.46 MW in new capacity. Solar energy projects dominated the month with 559.47 MW, while wind farms contributed 31.5 MW, small hydro plants 27.49 MW, and thermoelectric units 25 MW.
The report highlights that Rio de Janeiro, Minas Gerais, and Bahia led the national growth in 2025, with respective increases of 1,672.6 MW, 1,038.35 MW, and 1,011.7 MW. Minas Gerais, in particular, saw a strong surge in October, adding 11 new plants and 485.1 MW in a single month.
With these additions, Brazil’s total installed capacity reached 215.4 gigawatts (GW) as of November 3, according to ANEEL’s generation monitoring system. Renewable sources now account for 84.4% of the national energy mix, reinforcing the country’s leadership in clean power generation across Latin America.
This steady expansion of renewables has attracted growing participation from major energy companies, including Neoenergia (BVMF:NEOE3) and Engie Brasil Energia (BVMF:EGIE3), both increasing investments in wind and solar assets. Analysts expect solar energy to maintain double-digit growth through 2026, driven by new auctions and distributed generation projects.
