A ANEEL (National Electric Energy Agency) initiated Public Consultation No. 23/2025 to evaluate international experiences and propose regulatory alternatives to Article 17 of Law No. 14.300/2022, which deals with tariff rules applicable to consumer units with micro and mini-distributed generation.
The goal is to define how the costs and benefits of distributed generation (DG) will be calculated, especially for projects connected after January 2023, whose compensation rules will come into effect in 2029.
Distributed generation refers to power plants connected to the distribution network, located near or at points of consumption. It is primarily represented by solar photovoltaic energy on the rooftops of homes, businesses, and rural properties.
Published documents:
- Technical notes: A ANEEL He published methodological studies and comparative analyses with international models, which underpin the discussion;
- Preliminary reports: Present tariff impact scenarios and possible valuation methodologies;
- Final report: This will be consolidated after the deadline for contributions, serving as a reference for the final regulation.
The delay and its implications
Law 14.300/22, in its Article 17, stipulated that the ANEEL The methodology for calculating the costs and benefits of distributed generation should have been regulated within a defined timeframe. This deadline was not met.
Paradoxically, the delay gave the market time to expand, and investors moved forward even in the face of legal uncertainty. Many sellers of power plants did not inform buyers about the lack of clarity in the rules, which could affect future profitability.
Key concepts:
- Distributed Generation: Production of electricity close to the point of consumption, usually solar photovoltaic;
- Public Consultation: A participatory process to gather contributions from society before regulation;
- Valuation of the costs and benefits of distributed generation (DG): Assessment of the impact of DG on the electrical system, including loss reduction, infrastructure costs, and tariff balance;
- Distributed energy resources (DERs): Technologies such as solar panels, batteries, and electric vehicles;
- Smart grids: Digital systems that monitor and manage energy flows in real time;
- Microgrids: Local area networks capable of operating autonomously, increasing resilience.
Or turning point
The Brazilian electricity market is at a turning point. On one hand, millions of small generators empowered by new technologies; on the other, a centralized, robust model, but vulnerable to extreme weather events. The definition of compensation rules and the valuation of distributed generation will shape the future of the sector and society.
In defense of GD
Distributed generation (DG) strengthens energy resilience by enabling on-site generation, charging for electric vehicles, and integration with energy storage systems. This increases the security of the electricity sector and reduces risks in critical situations.
Brazil needs political will and proper regulation to move forward. Taking Subsidies opened by ANEEL This is an opportunity to define the direction of the sector and ensure that the energy of the future is safer, cleaner, and more accessible.

Congratulations on the report. We currently have over 500 distributed generation (DG) plants across Brazil and are seeking entrepreneurial partners for our project. If you are interested in saving money or expanding your project with us, just contact me on WhatsApp at +55 51 984863327.
In my view, distributed generation (DG) is indeed an important part of the future. It needs to be properly valued and incentivized. The end consumer with on-site generation needs to have greater added value for their generation. In other words, better exchange conditions for the kWh injected into the system.
