Voith Siemens Hydro Power Generation reports engineering and manufacturing has begun on four 25-MW Kaplan bulb turbines for the new 100-MW Rheinfelden hydroelectric project being built by Swiss-German hydropower utility Energiedienst Holding AG (EDH).
Voith Siemens said model testing of the units was completed in June before witnesses from EDH and its consultant, Fichtner Consulting. The model was developed jointly by Voith Siemens corporate and its Japanese subsidiary, Voith Fuji.
Voith Siemens is supplying the four 25-MW units and a separate minimum flow turbine. A consortium of Voith Siemens and Alstom Hydro (Switzerland) AG received a contract in 2006 to supply turbines and generators for the project, labeled Germany’s biggest onshore renewable energy plant.
EDH, an affiliate of German utility EnBW, broke ground in January for the new Rheinfelden, in Germany’s Baden Wuerttemberg State, on the Rhine River dividing Germany from Switzerland. (HNN 1/23/07) Start of operation is scheduled for 2010.
New Rheinfelden is to replace the 100-year-old, 25.7-MW Rheinfelden project at a cost of 400 million euros (US$510.4 million). The new plant is to more than triple generation to more than 600 million kWh per year compared with the current 185 million kWh.
