The energy transmission system consists of a network of transmission lines that spreads throughout the entire national territory with the objective of taking electric energy from the generating sources up to the distribution companies. This network is part of the Sistema Interligado Nacional (SIN) [National Interconnected System] that gathers companies of generation and transmission of energy from almost all Brazilian regions. Only 3.5% of the electricity production capacity of the country is outside SIN, in small isolated systems located mainly in the Amazon region.

With large distances to be covered from the plants to the consuming centers (especially as a result of the fact that many hydroelectric benefits are located away from the load centers), Brazil reaches a total of 85,817 km of transmission lines. The expansion of these lines has been promoted through auctions called by ANEEL, which favors the investor and offers the best price for the provision of the service. The segment demands high initial investments, but high EBITDA margins and presents low costs with O&M

This network of national proportions brings safety to the electric energy sector in Brazil, since it allows the exchange of energy among the different regions and complementary submarkets rede among themselves, when one of them presents scarcity in energy offer, usually due to the fall in the volumes of the reservoirs of the hydroelectric plants.

SIN also brings a few advantages to the national energy market.

• It offers free access to the market agents to the network, enabling the competition in the generation and commercialization of energy;
• Permits searching for price equalization;
• Expands the market available for each generator, permitting the optimization of the production flow of the generating park.
