As the project is to use water from the Empresa Bahiana de Agua e Saneamento (EMBASA) dam, Alstom will also take control of the spillway to maintain water supply to the city of Salvador and to protect downstream areas from flooding.

Pedra do Cavalo, situated on the ParaguaƧu river in the state of Bahia is to begin generating electricity in October this year, when it will form part of the local integrated power supply system.
