In recent years, Distributed generation has experienced significant expansion in Brazil, positioning itself as a strategic axis in the country's energy transition process. However, recent data show a slowdown in the number of new connections, which has opened a debate on the factors that are conditioning the sustainable growth of this energy modality.
Currently, distributed generation allows millions of Brazilians, companies and small businesses produce their own electricity from renewable sources, mainly solar photovoltaic. However, regulatory challenges, administrative difficulties and economic issues have emerged as obstacles that require urgent attention to ensure that this model continues to contribute efficiently to the national energy matrix.
Growth stagnation: causes and figures
According to the latest reports from the National Electric Energy Agency (ANEEL), The growth rate in new distributed generation connections has slowed significantly in 2025, with just over 367.700 connections to date, compared to 874.640 the previous year. Despite this decline, Brazil now has more than 3,6 million generating units distributed spread across more than 5.500 municipalities.
Among the reasons identified by sector associations such as the ABGD, the following stand out: increase in electricity grid access fees, bureaucracy in the authorization processes and restrictions imposed by distributors, often associated with alleged problems of reverse energy flow.
Furthermore, Import costs for photovoltaic components have risen considerably due to higher tariffs, which impact the profitability of new facilities. Added to this is competition from other business models in the energy market and the high interest rates which make project financing difficult, especially for residential consumers and small businesses.
Regulatory framework and sector demands
Industry entities and associations have defended the need for apply and respect the current legal framework, represented mainly by Law 14.300, to protect small producers and consumers. During recent public hearings in the Chamber of Deputies, representatives of organizations such as the Free Solar Movement, ABSOLAR and ABGD have demanded greater transparency in technical and administrative information by ANEEL and the distribution companies.
One of the main points of friction has been the regulation on the reversal of electrical flow, which, according to industry representatives, has served as a pretext to deny or limit access to distributed generation, hindering the entry of new players into the market. They emphasize the need to eliminate artificial barriers and find technical and financial solutions that will allow for continued participation and job creation in the sector.
The consensus among the entities is that Greater integration and collaboration between public agents, private companies and consumers It will be essential to strengthen the sector and prevent smaller producers from falling behind as large generators advance.
Brazil in the regional panorama and future potential
In the Latin American context, Brazil remains one of the countries with the largest installed capacity for distributed generation., exceeding 40 GW, of which more than 95% is solar energy. This figure places the nation above other emerging markets, both in production volume and number of generating users.
Investments in the Brazilian energy sector have been notable: In 2023, the country was among the top five recipients of clean energy project funding globally.This leadership has been possible thanks to a robust national interconnected system, which gives the country a competitive advantage in attracting capital and technological innovation.
To sustain this prominence, it will be essential Adapt regulations, facilitate access to investments, and modernize sectoral governanceDigitalization is key, as the demand for stable, clean energy in segments such as data centers requires long-term planning and the incorporation of advanced solutions, such as energy storage.
Energy transition and sustainability: immediate challenges
Brazil has made significant progress towards a mostly renewable energy matrix (with 84% of electricity generation coming from clean sources in 2024), although the expansion of distributed generation needs to balance growth, operational security and tariff fairness.
The Government's proposals to fully open the free energy market, eliminate cross-subsidies and reform the social tariff seek an inclusive and efficient energy transitionThe effective implementation of these measures will depend on technical coordination among system actors and the adaptation of the regulatory framework to an increasingly digital and decentralized environment.
The consolidation of distributed generation in Brazil requires overcoming administrative obstacles, ensuring a regulatory environment that encourages investment, and leveraging both human capital and technological innovation. Demand for solutions that make access to renewable energy production and self-consumption viable is growing throughout the productive sector.
