Voith Siemens Hydro’s scope of supply comprises the modernization and upgrading of four vertical Francis turbines (4.3 m runner diameter) with a rated capacity of 81 MW each, four 90 MVA generators (8.3 m rotor diameter) and four high voltage transformers of 95 MVA.

In order to maximize the future plant revenue, Voith Siemens Hydro, in close cooperation with Spanish Endesa, developed a techno-economically optimized hydraulic design that will ensure the best mix of energy production, storage capability and installed capacity. Through the modernization of Mequinenza hydro power plant the maximum output will be increased by 30% to 324 MW at a rated head of 47 m and by 20% to 384 MW at a maximum head of 53 m. Furthermore, the new design provides for smooth operation of the equipment from speed-no-load to maximum-full-load which will ensure maximum operating flexibility to the plant of Endesa.

Due to its upper reservoir storage capacity, which is Endesa’s largest in Spain, Mequinenza always was - and, through the liberalization of the energy market in 1998, even more has become one of Endesa's most important hydro power plants in terms of supplying energy during peak demand periods.
