At the transmission level in Peru, transmission lines are divided into principal and secondary systems. The principal system lines, all of which form part of the main grid, are accessible to all generation facilities connected to the grid and allow electricity to be carried to all customers. The transmission concessionaire of facilities that form part of the main transmission system receives tariff revenues and connection tolls reflecting a charge determined in accordance with the respective concession agreement. The secondary system lines typically link generation facilities or unregulated customers with the grid.

To the extent that a companys transmission assets were built pursuant to concessions granted by the Chilean government, the Chilean Electricity Law requires such company to operate the covered transmission system on an open access basis in which users may obtain access to the system by contributing towards the costs of operating, maintaining and, if necessary, expanding the system. Transmission companies recover their investment in transmission assets through tolls, or wheeling rates, which are charged to generation companies and final customers according to the following proportion defined by law: 80% to generators and 20% to customers in the central part of the network (the Common Influence Area, initially located between both nodes that includes at least 75% of the systems energy injection and demand) and in the rest of the transmission system, 100% to either generators or customers, according to the direction of the power flows. According to the Short Law the transmission companies become public service companies and their tariffs are determined every 4 years by Decree of the Ministerio de Economía, Fomento y Reconstrucción.
