Understanding Brazil's Energy Supply Market
Brazil's electricity market is divided into two main environments: the regulated market, where captive consumers buy power from local distributors, and the Free Energy Market, where eligible consumers can choose their supplier and negotiate prices and contract terms. Both segments are evolving rapidly, with ongoing reforms aimed at expanding consumer choice, integrating renewables, and modernizing tariffs.
