Atlântica Wind Park – Brazil’s tallest wind towers

Near the town of Palmares do Sul in the southern part of the federal state of Rio Grande do Sul, CPFL Renováveis recently built a wind park. CPFL Renováveis is a subsidiary of the largest private energy company in Brazil. Acciona Windpower supplied the towers and turbines for the new park in southern Brazil.

In the beginning, the Atlântica Wind Park consisted of four wind power stations with a capacity of 30 MW each that were put into operation successively from November 2013 to June 2014. At first, the erection of a total of 60 towers, each 80 m tall and with a capacity of 2 MW, was planned.

Each tower is 120 m high and has a capacity of 3 MW

CPFL Renováveis altered the plan and built the country's 40 highest wind towers each with a height of 120 m and a capacity of 3 MW – the largest capacity that has been achieved in Brazil so far. The wind towers consist of prefabricated concrete elements, and the rotors have lengths of 116 m.

CPFL Renováveis has leased the wind park for 20 years – the Brazilian government assigned the right of use during an energy auction in 2010. Including the new Atlântica Wind Park, CPFL Renováveis now operates 20 wind parks with a total operating performance of 719 MW. The parks are located in the federal states Rio Grande do Norte, Ceara and Rio Grande do Sul.

28,000 m of external tendons were installed

Since the wind towers in Atlântica Wind Park are exposed to high dynamic loads during operation, they were post-tensioned using external tendons. For the 40 wind towers, DSI supplied a total of 28,000 m of prefabricated post-tensioning tendons that were supplied coiled and ready to be installed to the jobsite. Six tendons in lengths of 120 m were used per wind tower.
