With total investments of R$26m ($7.3m), WEG won a tender to supply the electrical system, and will manage the projects as well as handle a three-year maintenance contract.
The projects should be concluded by mid-2017 and are part of Caixa Economica Federal's drive to reduce its carbon footprint.
WEG, which supplies electrical systems and turbines for wind power projects, has also started looking at solar.
