Equipment manufacturer Voith has been awarded a contract by owner Societe Electrique de l'Our S.A. to modernize four motor-generators at the 1,045-MW Vianden pumped-storage hydropower plant in Luxemburg.
The deal calls for Voith to design, construct, deliver and install rotors for each of the four horizontal units' motor-generators with the goal of "continued safe, stable operation of the highly flexible machines".
Voith said the unit rehabilitation will use its "new hammerhead groove construction' instead of the previous comb pole design, making the poles more easily exchanged and inspections easier to carry out.
Vianden is located on the border between Luxemburg and Germany, and was first put into operation in 1964 with subsequent expansions completed in 1976 and 2014. Electricity generated at the project is fed directly into the German grid, where it is marketed and distributed by RWE Generation.
