Os Brazilians who intend install solar energy systems from to 500 kWp in the segment of GD (distributed generation) have until 23:59 pm this Friday (7) to take advantage of the current transition rule.
As provided for by Law 14.300/2022, consumers who file the connection request for technology installation by that date they will have 90% of the Wire B da TUSD (Tariff for Using the Distribution System) not being compensated until 2031.
Yes, who to ask the access opinion after that you will see a new rule - that still will be defined by ANEEL (National Electric Energy Agency) – being applied from 2029 with progressive increases of this charge, as explained by Bernardo Marangon, director of Exact Energy.
“What changes is the following: in 2028, the consumer will no longer be able to offset 90% of Fio B in the case of plants smaller than 500 kWp and this 90% will remain until 2031. However, if the consumer files after July 7, the 90% of Fio B will remain until 2028 and, from 2029 onwards, there will be a new rule – which will still be defined by the ANEEL”, commented.
Regarding this definition of ANEEL, Thiago Bao Ribeiro, lawyer specializing in GD and CEO of Bao Ribeiro Advogados, highlights that the Agency had already presented to the market what the new compensation rules would be for those who file connection requests from Friday onwards.
“July 7th is the deadline for the ANEEL finalize what is conventionally called the settlement of accounts in the sector, the process of calculating the costs and benefits of GD. This process should be concluded this Friday, but unfortunately, there is no prospect of this happening any time soon,” he said.
Marangon also clarifies that plants larger than 500 kWp are no longer compensating 100% of Fio B, 40% of Fio A and the TFSE and R&D charges and this will remain until 2031. Those who file after July 7th, the compensation rule remains until 2028 (See image below).

To clarify further doubts on the topic, the Canal Solar will hold next Tuesday (11) the webinar “What will the compensation rules be like from July?”, with the participation of Bernardo Marangon.

I will definitely participate. Congratulations on the initiative.
Congratulations on the initiative, once again contributing to the updating of professionals in the solar energy sector.
In the area of solar energy, we have to be constantly updating ourselves and for this, nothing better than the webinars of Canal Solar, simply a professional and serious reference and source in the area. Congratulations!!!
