The transmission line connects three substations (Tucuruí Substation (500/230kV), Xingu Substation (500/230kV) and Jurupari Substation (500/230/69kV)) to the national grid as part of a wider objective to connect a number of isolated cities to the national grid, improve the reliability of the national grid and reduce fossil fuel power generation. The line runs through the difficult terrain of the Amazon and covers a linear distance of approximately 527 kilometres. The construction of such a large project through difficult terrain like the Amazon carries with it significant risks, such as environmental permitting, adverse site conditions, tropical weather and protests. These types of energy transmission projects in Brazil are often delivered in partnership with private partners transferring risks such as environmental permitting, financing and construction to the private partner. This project is an example of this type of a contract.

There have been two other similar PPP contracts signed under the broader objective, which cover more than 900 km of transmission lines and five additional substations.
