ANDRITZ HYDRO to supply electromechanical equipment for the Ribeiradio and Ermida hydropower plants, Portugal


International technology group ANDRITZ has received a contract from Electricidade de Portugal (EDP) to supply the complete electromechanical equipment for Ribeiradio and Ermida hydropower stations.

These new power plants will be built on the Rio Vouga river approximately 100 km south east of the city of Porto. Commissioning is planned for early 2014.

In Ribeiradio, the main stage of the scheme, a nominal flow of 125 m3/s will be utilized with a net head of 65 m. ANDRITZ HYDRO will supply the Francis turbine with a runner diameter of 3.7 m and a nominal output of 77 MW. The Ermida power station will be equipped with two double-regulated compact axial turbines (1,950 mm runner diameter and a nominal output of 3.8 MW each). The scope of supply for both hydropower plants also includes synchronous generators, control systems, hydromechanical equipment, as well as electrical and mechanical auxiliary systems.

ANDRITZ HYDRO is part of a consortium with the Portuguese company Efacec Engenharia S.A., which is responsible for local supplies and services. This complies with the customer’s request for a high proportion of supplies and services from Portugal.
