Solar energy increased its share of the Brazilian electricity matrix over the past year, jumping from 20,9% to 24,5% between January 2025 and January 2026. With this growth, the source has further consolidated its position as the second largest in the country, behind only hydroelectricity, according to data from [source missing]. ABSOLAR (Brazilian Photovoltaic Solar Energy Association).
The growth of solar power is occurring in a context of reduced participation from hydroelectric plants, which fell from 45,4% to 42,4% year-on-year. Although hydroelectricity remains the leading source, the decline reinforces a structural trend of diversification in the Brazilian electricity matrix, driven by the expansion of complementary renewable sources.
During this period, installed solar capacity increased from 53,9 GW to 63,7 GW, a growth sustained mainly by the expansion of distributed generation (DG), the commissioning of large centralized power plants, and the advancement of self-generation of energy by companies.
Diversification of the matrix intensifies.
Besides solar energy, other sources also showed significant changes in the energy mix. Wind energy maintained a practically stable share, going from 13,5% to 13,4%, while biomass registered a slight increase, from 6,9% to 7,1%.
Natural gas showed a slight decrease, from 7,5% to 7,3%, while oil and other fossil fuels increased from 3,0% to 3,5%, reflecting the occasional activation of thermal power plants to ensure the security of the SIN (National Interconnected System).
The share of coal also declined slightly, from 1,5% to 1,4%, and nuclear energy remained stable at 0,8%. Electricity imports, in turn, saw a slight increase, rising from 3,1% to 3,4%, especially during periods of higher demand and regional hydrological constraints.
Currently, Brazil has approximately 260 GW of installed capacity, considering all sources of electricity generation. “Solar energy will continue to advance towards becoming the number one source in the Brazilian electricity matrix. The speed of this advancement will depend on the environment and public policies implemented by the Federal Government, the Regulatory Agency, and other bodies in the electricity sector,” stated Rodrigo Sauaia, CEO of [Company Name]. ABSOLAR.

Congratulations on the report, Henrique. We are excited about the growth of our energy sharing project, which is already present in almost all of Brazil at low voltage and throughout the country at high voltage. We are looking for partners to expand our project. Anyone with a portfolio of clients who pay energy bills and are interested can contact us on WhatsApp at 51 984863327.
