Voltalia Launches Construction Of SSM3-6 In Brazil


Voltalia, an international player in renewable energies, announces the start of the construction of SSM3 to 6, taking the Serra Branca complex to a new level: 80% of its 2.4 gigawatts potential is now under construction or in operation.


Voltalia is launching the construction of the SSM3-6 (Solar Serra do Mel 3, 4, 5 & 6) solar power plant. With a capacity of 260 megawatts, the plant will begin production in the first half of 2023.


The SSM3-6 plant is backed by a 14-year power sales contract with Copel, a Brazilian Utiliy and historical partner of Voltalia:

  • Copel has been Voltalia’s partner in the SMG wind farm (108 megawatts) since 2015 as a minority shareholder.
  • In 2021, Copel acquired 100% of the VSM2 and VSM4 wind farms (187 megawatts in total), which will continue to be maintained by Voltalia over the long term.
  • Copel is one of the buyers of electricity from the SSM1&2 solar park (for 270 megawatts), currently under construction.

SSM3-6 is part of the Serra Branca complex. Entirely developed by Voltalia and located in the Brazilian state of Rio Grande do Norte, Serra Branca is the largest wind and solar complex in the world with a potential capacity of 2.4 gigawatts. Voltalia is the controlling shareholder of a significant portion of the projects located in the complex, the other projects being sold to partners. In all cases, Voltalia provides all or part of the services associated with the development, construction, and maintenance of the sold or retained plants.


Serra Branca generates one of the most competitive energies in the country. The site enjoys exceptional levels of wind and sunshine. In addition, the two energy sources are complementary, as the wind blows mainly at night in Serra Branca. The projects in the complex also benefit from common infrastructure (grid connection and access) and operational synergies. Thus, the construction of SSM3-6 (260 megawatts) will extend the ongoing construction of SSM1&2 (320 megawatts). In a second phase, SSM3-6 will be operated and maintained by the Voltalia teams in charge of the rest of this giant complex.

“With the launch of the construction of SSM3-6, Voltalia continues to ramp up its Serra Branca complex, alone or alongside partners such as Copel. More than 80% of the 2.4-gigawatt site’s potential is now in operation or under construction,” said Sébastien Clerc, CEO of Voltalia.
