Voith Siemens Hydro Power Generation’s Germany unit this month shipped the first motor-generator from its Heidenheim works, to the 910-MW Hotzenwald/Hornbergstufe Wehr pumped-storage plant in Germany’s Black Forest.
Schluchseewerk AG of Germany awarded a contract to Voith Siemens in 2007 to refurbish a 300-MVa motor-generator at the Wehr plant, part of the 1,270-MW Hotzenwald pumped-storage complex on the Rhine River. (HNN 5/14/07)
ï¿½The delivery of this generator clearly signals our ability to competitively supply from our German workshop new or modernized electrical components for such high-performance generators into our markets,ï¿½ Chief Executive Martin Andrae of Voith Siemens’ German Operating Unit said.
The 300-ton motor-generator, in operation since 1976 until its removal for refurbishment, is one of the largest of its kind in Europe. It is to be recommissioned in early 2009.
High-voltage tests on the newly manufactured stator took place in the Heidenheim facility. Generator poles are being overhauled in Heidenheim.
Work included renewal of the complete stator, 10 generator poles, and water-cooled coil. Although the contract price was not announced, Schluchseewerk said in 2007 it received three bids for the work ranging from 4.5 million euros (US$5.8 million) to 7.4 million euros (US$9.6 million).
Voith Siemens said a contract to rehabilitate a second Wehr unit has been booked, with work to begin in 2009.
