Voith and Iberdrola to modernise pump turbines in Spanish hydro plants

Technology group Voith and the Spanish electrical energy era firm Iberdrola have signed a contract to modernize 5 pump generators for the Spanish hydroelectric energy vegetation Torrejón and Valdecañas positioned on the Tajo river.

For the Torrejón hydropower plant, Voith will provide two semi-axial pump generators, every with an output of 43MW. The scope of provide contains the runners, information vanes, turbine covers, shafts and bearings, in addition to hydraulic and digital governors.
