São Paulo - Minas Gerais power line
1,600 kilometres of power line in Brazil: Our largest grid project in the world
Iberdrola projects Electrical network Neoenergia Brazil
The new electric power line between the states of São Paulo and Minas Gerais, with a length of more than 1,600 kilometres, is Iberdrola's largest grid project in the world. An award that reaffirms the group's expansion in the electricity distribution and transmission segment and consolidates its commitment to the South American country.
São Paulo-Minas Gerais power line
Iberdrola, through its Brazilian subsidiary Neoenergia*, acquired at auction in 2022 the concession for the construction of 1,600 kilometres of electrical grid between the north of Minas Gerais and the state of São Paulo, which its largest power grid line in Brazil.
The mega-construction project aims to expand the power line capacity of the northern region of Minas Gerais, so that part of the renewable energy generated there can be transported to the neighbouring state of São Paulo. The new power grid, facility operational from 2026, will have four high-voltage lines, three of them at 500 kV and one line at 440 kV, as well as the new 500 kV New Bridge 3 substation.
The second includes the construction of 291 kilometres of lines in the state of Mato Grosso do Sul, with two 230 kV lines and a 230/138 kV substation. The objective has been the integration of the small hydroelectric power plants Fundãozinho, Areado and Bandeirante and the connection of the distribution in the Paraíso region.
The works were completed more than 15 months ahead of the deadline set by ANEEL and with an investment of approximately 4.2 billion reais (around 669 million euros) and the creation of more than 11,000 jobs.
The acquisition of this important contract in the Brazilian market reinforces the Iberdrola group's expansion in the renewable energy transmission grids segment and consolidates our commitment to the South American country, where it already has more than 740,000 kilometres of power lines in 2024.
