Energy Comercialization

Freedom to choose from whom you buy your energy

What is it?

Free market or free-trade environment is a setting for buying and selling energy where conditions and prices are defined directly with the customer.

How does It work?

RCE - Regulated Contracting Enviroment (Regulated Market)

Energy contracting in the Regulated Market is performed between the captive consumer and the distribution concessionaire to which the consumer is connected.


This method of contracting does not allow price negotiation, that is, each consumer unit only pays one monthly energy bill, including energy distribution and generation services, with rates established by the Brazilian Electricity Regulatory Agency (ANEEL – Agência Nacional de Energia Elétrica).

FCE - Free Contracting Environment (Free Market)

The energy free market is a business environment where sellers and buyers can freely trade electric power with each other. This allows industrial and commercial consumers to contract their energy supply, negotiating price, terms and commercial conditions directly with generators and marketers. By contracting energy in a customized way, the activities become more competitive.


The negotiation must comply with the trading rules established by the Electrical Energy Trading Chamber (CCEE – Câmara de Comercialização de Energia Elétrica). Each consumer unit pays a bill referring to the distribution service to the local concessionaire (regulated rate) and one or more bills referring to the purchase of energy from the generator or marketer (negotiated contract price).
