The 15-year loan will underpin the R$123.4m Barra dos Coqueiros wind farm in Sergipe state, for which Chinese turbine manufacturer Sinovel has supplied 23 of its 1.5MW machines.
A number of reports had linked CDB finance to the project, but Desenvix has now confirmed that the agreement was signed in Beijing earlier this month.
The wind farm will be fully operational within the next few weeks.
