Under the terms of the EUR80M contract, Voith will overhaul the generators and turbines as well as the associated electromechanical systems. In addition, many additional components will be completely renewed.

In operation since 1978, Água Vermelha has six units with a total capacity of 1396MW. It is the largest plant owned by energy company AES Tietê and is operated by ONS.

In a statement, Voith said the new contract is one of the largest deals for the modernization of a hydropower plant in Brazil, and the largest ever to be undertaken by a single company.
