This is the second of three stages to be completed at the Cristal wind power complex, with the first phase, Primavera, finalised earlier this year.
São Judas is comprised of 13 2.3MW Siemens turbines.
Cristal will have a total installed capacity of 90MW once completed, after an overall investment of about €165m ($227m).
The new wind farm brings EGP's installed capacity in Brazil to more than 207MW, of which 93MW is hydro. In addition, the company is building the Curva and Serra Azul wind farms in the state of Bahia.
