By Brazil Stock Guide – Brazil’s electricity regulator Aneel approved on Tuesday, Jan. 2, its regulatory agenda for 2026–2027, setting the groundwork for opening the power market to low-voltage consumers in 2027. The plan targets so-called Group B users — households, small retailers and service providers — marking a significant step in the country’s retail electricity liberalization.
The regulator intends to intensify discussions over the next year to enable residential participation in the free market, following the 36-month deadline established by the provisional measure that restructured Brazil’s power sector. Aneel’s leadership has signaled that the regulatory process will advance ahead of the legal cutoff.
The agenda also includes new rules for distributed generation, introducing updated observability, operability and controllability requirements for Distributed Energy Resources (DERs). Further changes planned for 2026 address the management of surplus distributed generation injected into distribution networks.
Another key item is the 2026 regulation of constrained-off conditions for hydroelectric generators — a mechanism applied when the national grid operator restricts plant operations due to external system constraints. The measure is expected to affect producers across the hydropower segment.
