The main representative entities of the solar energy sector in Brazil released, this Thursday (23), an open letter to the National Congress in defense of Law No. 14.300/2022, the Legal Framework for GD (Distributed Generation).
The document, signed by ABSOLAR (Brazilian Association of Photovoltaic Solar Energy), ABGD (Brazilian Association of Distributed Generation), INEL (National Institute of Clean Energy) and MSL (Free Solar Movement), makes a technical and institutional appeal for the maintenance of the current rules and criticizes possible changes under debate within the scope of Provisional Measure No. 1.304, which deals with the reform of the electricity sector.
According to the associations, any change before the completion of the technical studies required by law could create legal uncertainty and put millions of jobs and investments already made at risk.
The letter recalls that Law 14.300 was approved by Congress after two years of debate and provides for a transition by 2029, in which consumers who generate their own energy will gradually start paying for use of the grid.
For the entities, this model ensures economic balance and predictability for the sector, while also offering time for technological evolution and the reduction of battery storage costs, which are still inaccessible to most residential and rural consumers.
"Amending Law No. 14.300 would be a social and economic injustice. Thousands of families, small businesses, and rural producers have taken out loans from cooperatives, public banks, and local financial institutions to generate their own energy, relying on the legal stability guaranteed by the National Congress," the document highlights.
Delay of ANEEL and lack of technical basis
The document criticizes the delay of the ANEEL (National Electric Energy Agency) in delivering the valuation of the costs and benefits of micro and mini distributed generation, a study that should have been presented in July 2023.
Without this survey, the associations claim, any attempt to create new charges or fees lacks a technical basis and violates the principle of reasonableness.
Energy waste and inequality
The organizations also point out that the true challenge facing the electricity sector is structural. They highlight that, according to data from the 2025 National Energy Balance, the system's technical losses reach 112,5 TWh per year, equivalent to 14,7% of all electricity consumed in the country—more than the entire commercial sector's consumption.
“Even so, through Provisional Measure No. 1.304, the restriction of distributed micro and mini solar generation is being discussed, precisely the model that contributes most to reducing these losses (…) Distributed generation is part of the solution and not the problem, as it directly combats the inefficiency that has made energy more expensive for Brazilians for decades,” the letter states.
International message and COP30
At the end of the document, the entities state that any attempt to restrict GD would send a negative signal to the international community, especially on the eve of COP30, which will be held in Belém (PA) in November 2025.
"Distributed generation is an instrument of democratization, social inclusion, and regional development, the path to a fair energy transition, made with citizens, not against them," the signatories conclude.
