The Brazilian electric power sector has two environments of energy procurenment: Free Contracting Environment - FCE (ACL) and the Regulated Contracting Environment - RCE (ACR). The first allows the acquisition of the energy directly from the provider of energy or from an intermediate agent, through bilateral contracts, when prevails the free negotiation of price, quality and demand. Already in RCE the recruiting is formalized through regulated bilateral contracts, denominated Contracts of Commercialization of Electric Power in the Regulated Emvirinment - CCERE (CCEAR), that have been accomplished among trading agents (dealers, generators, independent producers or self-producers) and buyers (distributors) that participate in the purchase and sale auctions of electric power.
In the FCE can perform the generation agents: dealers, energy importers, energy exporters and free consumers. The potentially free customers they present the following characteristics:
• Demand > 3MW linked after 1995 with any tension level;
• Demand > 3MW linked before 1995 with tension > 69kW;
• Demand > 0,5MW, any tension can buy SHP or other promoted energies.
