EPE (Energy Research Company) has updated the PDGD (Data Panel for Micro and Mini Distributed Generation) with consolidated data for 2025.
The numbers show that, even in the face of challenges related to flow reversal, installed capacity increased from 36,2 GW in 2024 to 45 GW in 2025, representing an increase of 8,8 GW over the period.
The number of consumers served reached 7,2 million, while the estimated generation for the year reached 54.483 GWh.
According to EPE, the 2025 performance represents the second-best annual result for distributed generation in the country, second only to 2024, when more than 10 GW were added.
In comparison, 2023 saw approximately 8,3 GW of expansion, while 2022 accounted for 8 GW. Prior to that, the highest annual volume had been 4,6 GW.
The tool gathers data from ANEEL (National Electric Energy Agency) combined with studies from EPE, allowing interactive visualization and download of the databases, which increases transparency and monitoring of the sector.
Solar energy dominates
Analysis of the composition of installed capacity confirms the almost absolute predominance of solar photovoltaic energy, which accounts for more than 95% of distributed generation in Brazil. Other sources, such as hydroelectric, thermal, and wind power, maintain a residual share throughout the entire historical series.
In practice, this means that the advancement of micro and mini-distributed generation is directly linked to the expansion of solar generation, especially on rooftops and in small decentralized systems.
The number of distributed generation (DG) systems also showed significant growth, reaching approximately 4 million units in 2025. This trend reflects the widespread adoption of the technology, which is no longer restricted to large consumers and has begun to reach a broader audience.
Meanwhile, the total number of consumers with distributed generation (DG) grew even faster, exceeding 7 million. This disconnect between systems and consumers indicates the advancement of models such as shared generation and remote self-consumption, in which a single system can serve multiple consumer units.
Consumption profile
The data shows a significant shift in consumer profiles. The residential segment has taken the lead in expansion, becoming the majority over the last few years. The commercial segment, which initially accounted for a large portion of projects, has lost relative market share, although it remains relevant in absolute terms.
The rural sector has shown consistent growth until recently, while segments such as industry and the public sector continue to have a smaller share. In addition to quantitative growth, the panel highlights an evolution in generation models.
On-site generation still predominates, but there is a gradual increase in shared generation and remote self-consumption. This diversification indicates greater sophistication in the market, with new solutions that expand access to distributed generation (DG) for consumers who do not have the physical space to install their own systems.
Transparency
With the updated dashboard, EPE expands access to detailed data on the evolution of MMGD, allowing for more precise analyses by market participants, policymakers, and investors.
The numbers confirm that micro and mini-distributed generation has established itself as one of the main drivers of the energy transition in Brazil, with a trend towards continued growth in the coming years.
