Brazil Energy Electricity Market Liberalization

Brazil is moving forward with the liberalization and digitalization of its electricity market. On October 27, 2026, the National Electric Energy Agency (ANEEL) approved new rules for consumers served at medium and high voltage, including many commercial and industrial businesses. The measures aim to make it easier for eligible consumers to choose their electricity suppliers, improve access to energy information, and strengthen competition among electricity retailers.

A key development is the introduction of Open Energy, a framework that will allow consumers to access their electricity consumption, billing, and metering data and authorize third parties to use this information, subject to Brazil’s data protection law. This could make it easier to compare electricity offers, identify potential savings, and access new energy-management services. Within 12 months of publication of the regulation, ANEEL expects standardized access to consumer data and an online platform to compare offers from electricity retailers. Standardized systems for sharing data with authorized third parties are expected within 24 months.

The new rules also simplify the process of switching to the free electricity market. Eligible consumers will be able to start the migration process without first terminating their existing electricity supply contract, reducing administrative steps and the risk of a gap in supply arrangements. For most consumers eligible for the simplified process, the migration period will be reduced from 180 to 90 days. The rules also seek to ensure fairer competition by requiring clearer distinctions between distribution utilities and their affiliated electricity retailers. Among other measures, they restrict joint advertising and the use of distribution utilities’ institutional channels to promote affiliated retailers. These requirements will help consumers better understand that they can choose suppliers other than the retailer affiliated with their local distribution utility.

For now, the changes apply to medium- and high-voltage consumers. The expansion of the free market to households and other low-voltage consumers will be addressed separately under ANEEL’s 2026–2027 Regulatory Agenda.
