Graz/Vienna, 21 December 2006.  The consortium VA TECH HYDRO GmbH / MCE Industrietechnik Linz GmbH & Co, under the leadership of VA TECH HYDRO GmbH, received an order from Cleuson Dixence Construction SA, Switzerland, for the rehabilitation of the pressure shaft for the 1,200 MW power station Cleuson Dixence based in the canton Wallis, Switzerland.  The total order value amounts to approximately 127 MEUR (thereof more than half for Andritz VA TECH HYDRO).  Erection works will commence in mid of 2007, the start-up of the commercial operation is planned for the end of 2009.

With a gross head of 1,880 m the hydropower station Cleuson Dixence has the world’s highest gross head.  The three pelton turbines with an output of 423 MW each, delivered by Andritz VA TECH HYDRO in 1998, also represent world record.

In December 2000, the steel tunnel lining of the power station Cleuson Dixence burst.  After detailed investigations on the causes of the damage a general rehabilitation concept was provided.  In 2003 Énergie Ouest Suisse SA and Grande Dixence SA founded Cleuson-Dixence Construction SA, with the goal to rehabilitate the power station.

In the course of the rehabilitation the entire pressure tunnel will be provided with an additional steel lining on a length of 4 km.  The total weight of this new lining amounts to 12,600 tons.  The design pressure of 200 bars is presently the world-wide highest design pressure for a penstock of a hydropower plant.  In order to secure the high quality requirements of the new steel lining an extensive qualification program for the material and the weldings is to be accomplished before start of manufacturing.
