Publication and promise of reform in the electricity sector
Provisional Measure 1.300/2025, published by the Federal Government in late May, promised to reform strategic aspects of the Brazilian electricity sector. Among the main advances was the expansion of the TSEE (Social Electricity Tariff), which is expected to benefit up to 17,1 million vulnerable families. However, its progress through the National Congress has been anything but smooth.
Political delays and risk of loss of validity
After receiving more than 600 parliamentary amendments, the provisional measure faced a significant delay from the outset: although the joint committee responsible for its analysis was appointed on May 26, its installation was stalled for weeks due to a lack of party nominations and political disputes involving the President of Congress, Davi Alcolumbre (União-AP), and the Minister of Mines and Energy, Alexandre Silveira. The impasse exposed fissures in the government's negotiations and raised concerns about the measure's viability within the 120-day statutory deadline.
Sector reacts: live stream details the impacts of the MP
While the proposal “hibernated” in Congress, the electricity sector reacted. On May 29, Canal Solar hosted a special livestream to explain the technical impacts of the provisional measure. Experts highlighted, among other points, the opening of the free energy market, the end of discounts for incentivized sources, and changes to the rules for self-production. According to analysts, these changes would have direct effects on both consumers and entrepreneurs in the photovoltaic sector.
Crisis in the final stretch: distributed generation under threat
But the biggest flashpoint was yet to come. In the final stretch of the process, on September 11, the vote in the Chamber of Deputies was suspended due to lack of consensus. Parliamentarians and representatives of the distributed generation (DG) sector mobilized against sections that granted ANEEL (National Electric Energy Agency) the power to establish multi-part tariffs, allowing separate charging for the use of the distribution network, which could compromise the economic viability of small generators and prosumers.
National mobilization put pressure on Congress
Faced with a strong reaction from civil society, industry associations and intense lobbying in Parliament, these provisions were removed from the final text.
“The mobilization of the sector was fundamental to preserving distributed generation, guaranteeing legal security for small generators and residential consumers,” highlighted Congressman Lafayette de Andrada (Republicanos-MG), one of the main articulators of the cause.
Approval on the last day of the deadline
On the last day of the deadline, September 17, the Chamber finally approved the MP with the changes. Hours later, the Federal Senate ratified the decision, maintaining the government's core provisions, such as the expansion of the Social Tariff, and excluding the articles that jeopardized the GD.
Next steps: presidential sanction and new MP
The measure now awaits presidential approval, concluding a process marked by uncertainty, conflict, and mobilization. The debate on multipart tariff modalities, removed from the final version, is expected to be resumed in the sector's next Provisional Measure, MP 1.304.
