Brazil electricity sector regulatory developments

Brazil is implementing regulatory changes to manage its electricity sector, focusing on both generation assets and distribution technology.

In September 2026, the Ministry of Mines and Energy initiated a public consultation regarding hydroelectric concessions expiring by 2032. The proposal seeks to address the future of over 15 gigawatts of assets through potential new auctions or contract extensions. To prevent market concentration, the Ministry is considering ‘trava’ or limits on asset acquisitions. Industry stakeholders have expressed varying interests, with some advocating for competitive auctions and others seeking contract extensions. These existing plants are considered vital for grid stability as intermittent solar and wind generation increase.

By October 2026, regulatory focus expanded to the distribution network through Normative Ordinance MME nº 126/2026. This mandate requires energy concessionaires to implement smart metering systems for 2% of consumer units annually over a 24-month period. These systems must support remote reading, cybersecurity, and anti-fraud capabilities. Additionally, the regulation outlines a phased expansion of the free energy market, allowing industrial and commercial consumers to migrate in November 2027, followed by residential consumers in November 2028.
