Ribeiradio Hydroelectric Development
 The Ribeiradio – Ermida development is situated in the Vouga river and its purpose is the water supply and power generation.
The integrated development of the Vouga water resources has been analysed over the last three decades, within various studies, most of them elaborated by COBA. The Ribeiradio dam has also been object of many studies made by COBA, essentially during the last ten years.
In 2007, the Instituto da Água (INAG) launched a call for tenders for the Construction and Exploitation of the Ribeiradio-Ermida Development. One of the bidders was the consortium EDP-EVIVA, for whom COBA prepared the preliminary design that founded their offer.
This consortium was the winner of the project and then COBA has been committed to execute the Tender Design, Final Design and Technical Assistance.
The project involves:
- Ribeiradio gravity dam, with a height of 75 m and 295 m crest length:
- the Ribeiradio power plan provided with a non reversible unit with a power capacity of 72 MW;
- the afterbay Ermida with a height of 29,5 m and a crest length of 125 m to control the flows released by the Ribeiradio power plant and the Ermida power plant with a power capacity of 7,1 MW..
