President Lula Opens Brazil’s Energy Market to 90 Million Consumers, Promising Lower Bills

President Luiz Inácio Lula da Silva has signed a decree that fundamentally alters Brazil’s power sector, opening the country’s free energy market to nearly all low-voltage consumers, including commercial, industrial, and residential users. The move, which is designed to introduce competition and lower costs, will allow an estimated 90 million consumer units—about 60% of the energy consumed in Brazil—to choose their electricity supplier by November 2028. The Ministry of Mines and Energy estimates that the liberalization could reduce the energy purchase component of the electricity bill by 20% to 22% for these consumers.

The decree marks a dramatic shift in how Brazilians purchase electricity. Currently, most consumers are forced to buy power exclusively from their regional, often monopolistic, local distribution company. This is known as the regulated market. Under the new rules, consumers will be able to migrate to the Free Contracting Environment (ACL), negotiating prices and contracts directly with energy generators or traders, much like choosing a telecommunications provider. The ability to choose a supplier has historically been restricted to large-scale, high-voltage industrial clients. The expansion to low-voltage users means small businesses and households across the country will gain this same freedom.

The massive market migration will be implemented in two phases to manage the transition for the National Electric Energy Agency, ANEEL, Brazil’s electricity regulator. The first phase targets commercial and industrial low-voltage consumers, who will gain the choice to select their supplier starting in November 2027. The second phase, which includes all other consumers, such as residential users and rural properties, will begin in November 2028. The decree also includes provisions to ensure continuous supply, such as establishing a "Supplier of Last Resort" (SUI) to step in if a consumer's chosen supplier fails, adding a layer of market security.

While the decree sets the timeline, the hard work of building out the new system now falls to sector regulators. ANEEL and the Ministry of Mines and Energy (MME) must develop regulations to modernize distribution networks, handle the fair allocation of costs, and establish the technical mechanisms required for millions of new customers to switch providers. This next regulatory stage is essential to ensure that the projected cost savings and benefits of competition are fully realized by consumers without compromising the stability of the grid.

What it touches The new framework will reshape the financial landscape for Brazil's utility sector. Generation companies (GENCOs) and energy trading firms stand to benefit from a massive increase in the potential customer base, while local distribution companies (LDCs) will need to adapt their business models as they lose their traditional monopoly on energy supply to small customers.
