Federal deputy José Medeiros (PL-MT) has introduced a bill to prevent the creation of new charges for consumers with distributed solar energy generation systems.
Bill 3.149/2026 establishes the Statute for the Protection of Solar Energy Consumers, aimed at residential consumers, small entrepreneurs, cooperatives, associations, and rural producers.
One of the main proposals is to prohibit the retroactive collection of charges, fees, contributions, or compensatory tariffs on systems that are regularly installed and connected to the electricity grid.
The text also stipulates that no regulatory change may reduce economic rights acquired by consumers who invested in distributed generation under previous rules. Energy compensation contracts must preserve the conditions in effect on the date of their signing.
Another point of the project establishes that any new charge or increase in fees for micro and mini-distributed generation will depend on the approval of a specific federal law.
With this, the ANEEL (National Electric Energy Agency) It would be prevented from establishing, by resolution or other sub-legal act, charges that increase the costs for consumers participating in distributed generation.
The bill stipulates that consumers with distributed generation will be entitled to maintain the economic and regulatory conditions in effect at the time of system connection for at least 25 years.
The proposal also stipulates that the Union should promote policies to encourage distributed generation as a means to reduce demand on the electrical system.
The project creates specific guarantees for rural producers who use electricity in agricultural activities.
According to the text, these consumers should be protected against charges that compromise the economic viability of investments in distributed generation.
Also prohibited is the creation of a specific additional charge on energy produced for self-consumption on rural properties.
According to the project's justification, the measures aim to offer predictability to consumers who have invested their own resources or taken out long-term financing to install photovoltaic systems. The proposal will still be analyzed by the Chamber of Deputies.
The project emerges amid pressure on distributed generation.
The project was presented at a time of increased discussions about the role of distributed generation in the operation and cost of the electrical system.
One of them involves the automatic application of White Tariff For low-voltage consumers. The model establishes different values for energy depending on the time of day.
For consumers with photovoltaic systems, the change could reduce the value of credits generated during the day and increase the cost of energy consumed at night.
There are also suggestions for distributed generation to participate in generation cuts aimed at controlling surplus energy in the system.
The possibility gained traction in discussions about curtailment, although it still faces legal and technical challenges related to the guarantees provided for in Law 14.300/2022.
More recently, the ANEEL It has opened Public Consultation 33/2026, which proposes requirements for monitoring and managing distributed energy resources.
The rules would allow distributors to monitor the operation and, when necessary, control the power injected by solar generation systems, batteries, and other equipment connected to the grid.

We need to find a middle ground where we continue to encourage renewable energy while remaining economically sustainable. In my view, they seem to want to make micro and mini-generation increasingly unviable.
Taxing the sun, what have we come to!!!
