The Solar Coalition, led by MSL (National Association of Free Solar Movement), filed this week, in Brasília (DF), a letter addressed to deputies and senators asking for support for the amendments presented to MP 1.304/2025 (Provisional Measure 1.304/2025), which is being processed in the National Congress.
The group, made up of representatives from 21 states and more than 5 municipalities, warns that the MP could cause an “immediate rupture” in the Legal Framework for Distributed Generation, created by Law 14.300/2022, and compromise the legal security of the sector, which accounts for more than 2,3 million solar systems installed in the country.
The document highlights that the proposal creates the ECR (Resource Complement Charge), a new cost that, if applied to micro and mini generators, could make the current model of decentralized solar generation unfeasible.
The movement also calls on the government and Congress to reject the reintroduction of the multipart tariff, mechanism removed from MP 1.300/2025, but which could be included again in the text under consideration.
According to the CoalizãoSolar, the multipart tariff would represent a significant increase in electricity bills for low-voltage consumers and would limit the expansion of solar energy in the country. The letter also requests that the sector remain exempt from new charges until 2045, as originally planned under Law 14.300.
Amendments in defense of GD
Among the main amendments defended by the Solar Coalition are Amendment No. 402, authored by Senator Irajá (PSD-TO), which creates the People's Energy Program, providing up to 220 kWh of free solar energy per month for low-income families; and Amendment No. 432, also by Irajá, which guarantees the integrity of Law 14.300 and protects consumers against blocking or undue loss of generation credits.
The group also supports Amendment No. 201, by Congressman Beto Pereira (PSDB-MS), which guarantees the right to a monomial and white tariff until 2045, and amendments 382, 383 and 435, which prohibit the charging of the ECR, protect microgeneration of up to 75 kW and prevent connection restrictions by distributors and the ANEEL.
Jobs and economic impact
The Solar Coalition emphasizes that the distributed generation sector is responsible for generating hundreds of thousands of direct and indirect jobs across the country and has the potential to create 3,2 million new jobs by 2030.
The movement argues that current rules already provide for a gradual transition to charging for network use, without free services, and that sudden changes could “shake the confidence of investors and consumers.”
"Our request aims precisely to comply with the law and avoid disruptions that harm small generators and the local economy," says Hewerton Martins, President of MSL, the national solar energy confederation that brings together the State Distributed Generation Fronts.
According to him, the Confederation is expanding and should end the year with legitimate sector representatives in each state. He also points out that, according to the Energy Research Company (EPE), distributed solar generation represented only 5,6% of Brazil's energy in 2024.
"This volume is still too small to affect the Brazilian electricity system. It's much more about the interests of large groups that don't want consumers to be active agents in the energy transition," he points out.
Martins also emphasizes that if MP 1304 changes what was established by Law 14.300, the agribusiness sector will be one of the most affected as it will not have the chance to use solar energy to reduce production costs.
“A Open Letter from Aprosoja Brasil already signals to the FPA (Parliamentary Front for Agriculture) the concern of disruption that directly affects agriculture, both small, medium and large producers will be affected”, he states.
The document is supported by state and sector leaders in distributed generation and represents the joint position of the Solar Coalition, which brings together associations, parliamentary groups, and companies involved in solar energy across the country. Learn more clicking here.
