Assets in operation
Neoenergia | Dourados
The Neoenergia | Nova Porto Primavera — Rio Brilhante Transmission Line, from the Dourados project, is the first delivery of lot 4 of the auction held by ANEEL in April 2017, which will strengthen the electrical system in Mato Grosso do Sul. In this first phase, two substations were expanded and 327 towers were built over 147 kilometers long. The last one to be hoisted, about 80 meters high, is located inside the Paraná River, making the implementation more complex because it requires the assembly to take place gradually, using vessels and cranes.
