The state of Maranhão has surpassed the mark of 1 GW of installed solar power capacity in the distributed generation (DG) segment, according to data from... ANEEL (National Electric Energy Agency) updated this Monday (25). With this, Brazil now has 16 states with at least 1 GW operational in this modality.
In total, self-generated solar energy already amounts to more than 48 GW installed throughout the country, distributed across approximately 4,4 million photovoltaic systems. Together, these plants supply approximately 7,8 million consumer units in all regions of the country.
Southeast and South regions concentrate the largest installed volumes.
Among the states with the largest installed capacity in distributed solar generation, the following stand out:
- São Paulo, with 6,68 GW;
- Minas Gerais, with 5,90 GW;
- Paraná, with 4,33 GW;
- Rio Grande do Sul, with 3,69 GW;
- Mato Grosso, with 3,15 GW.
The following appear:
- Bahia (2,80 GW);
- Goiás (2,33 GW);
- Santa Catarina (2,22 GW);
- Rio de Janeiro (1,87 GW);
- Mato Grosso do Sul (1,84 GW);
- Ceará (1,74 GW);
- Pará (1,65 GW);
- Pernambuco (1,49 GW);
- Espírito Santo (1,25 GW);
- Rio Grande do Norte (1,06 GW);
- Maranhão (1,02 GW).
Ten states have yet to reach 1 GW.
Despite the strong growth of distributed solar generation in Brazil, ten states have not yet surpassed the 1 GW installed capacity mark. The closest to this level are:
- Piauí (853 MW);
- Tocantins (723 MW);
- Rondônia (675 MW);
- Alagoas (633 MW);
- Paraíba (611 MW).
The Federal District (which is not considered a state, but appears separately in the data) ANEEL) also remains below the first gigawatt mark, with 580 MW installed to date.
Remote regions still face structural challenges.
The smallest installed volumes continue to be concentrated mainly in states in the Northern Region, where factors such as low population density, logistical difficulties, and the presence of remote communities still limit the advancement of distributed generation.
Even so, the growth of solar energy in these regions has been accelerating in recent years, driven by lower technology costs, greater access to credit, and the expansion of electrification in isolated areas.
Currently, the states with the lowest installed capacity in solar distributed generation are:
- Amazonas (313 MW);
- Sergipe (302 MW);
- Acre (182 MW);
- Amapá (160 MW);
- Roraima (121 MW).
