​​​​​​​Wind Farm Engineer Mario Cebreiro

In May 2018, we inaugurated the Mario Cebreiro Wind Farm, which contributes 100 MW of renewable energy to the national grid. It demanded an investment of AR$3,000 million. The wind farm, located just 20 kilometers away from Bahía Blanca, province of Buenos Aires, is composed by 29 wind turbines, each one with a total diameter of 126 meters. For the installment of these wind turbines, highly sophisticated works were undertaken on platforms and foundations similar to other wind farms of the same characteristics around the world. The generators, coupled to the axis of the turbine (87 meters tall), generate electricity in 33 kV. Several internal collector circuits were installed and connected to two transformers of 132 kV. Consequently, the energy is delivered to the substation of Bahía Blanca, property of TRANSBA, located on the opposite side of provincial Route 51 (Ruta Provincial 51), in front of Mario Cebreiro Wind Farm. This Wind Farm was the first from of such magnitude to be commissioned under Renovar 1.
