A strategic power line for the development of the Brazilian grid: 158 km, 10 companies, 500 technicians


A significant investment which will enable the development of the Brazilian electricity grid and the increasing integration of renewables into the transmission grid. Luigi Ferraris, Terna CEO, highlighted the importance of the new 230 kV Santa Maria 3 – Santo Angelo 2 power line during the unveiling of the works in Brazil at a ceremony hosted by the Italian embassy with Brazil’s energy sector representative institutions.

What added value does infrastructure such as this bring?

Making the most of our unique technological and innovative know-how that we have developed as a model of excellence in our core business, and thanks to proactive collaboration with state environmental bodies, we have been able to create a sustainable primary infrastructure which will enable Brazil to continue on its path of developing renewables in harmony with the new energy and decarbonisation ecosystems.

In your opinion, what is the role of the grids in the development of a country such as this?

In Brazil, and in Latin America in general, investments in transmission infrastructures are necessary to meet the growing electricity demand and for the promotion and integration of renewable energy. But there is even more at stake: the grids are strategic infrastructures and represent a driving force for sustainable development and an enabling factor for the energy transition of each country. And they are also a lever for encouraging further economic growth, creating employment opportunities and contributing to reducing poverty.

What is Terna's role in this South American country?

With over 80% of electricity produced from clean sources and wind production having increased by 20% in the last year alone, Brazil currently represents the largest Latin American energy market and is among the top five in the world for its development potential. In this context, Terna is present with two concessions for the construction and management of two electricity transmission lines spanning a total length of more than 500 km.

One of these is the power line that has just been unveiled...

The construction of the new 158 km Santa Maria 3 – Santo Angelo 2 power line in Rio Grande do Sul has seen the involvement of 10 companies and a peak of 500 technicians during the 12 months of work. This project will allow for the integration of energy generated by wind farms in the south of Brazil into the country’s national transmission grid.

What is the importance of the institutions in the success of these investments?

I believe it is fundamental to be able to continue to count on the important diplomatic and institutional support, with the particular aim of ensuring the certainty and stability of the regulatory and legislative framework. We also aim to strengthen partnerships with the country’s leading financial institutions and development banks.
