VA TECH HYDRO in Ravensburg and VA TECH ELIN EBG Salzburg together have successfully won an order for the delivery, erection and commissioning of two modern PIT turbines for the Rott hydropower station.
The scope of delivery includes the mechanical and electrical hydro generating equipment such as turbines, gears, generators and digital control equipment. The new PIT turbines, will replace the existing three Arno-Fischer bulb turbines (runner diameter 1,950 mm) built in the 1950's. Meanwhile two virtually identical turbines have also been sold for the Jettenbach hydropower station in Bavaria.
The new Rott hydropower station will replace the aged Saalach plant located between Salzburg and Freilassing built during WWII and completed in 1950 due to shortages in construction materials. Since then, the three single regulated turbines have delivered 19,000 MWh annually to the city of Salzburg. Today, the existing power station can no longer be run economically without major redevelopment work due to its age and the deterioration of the generating equipment. Consequently, the local energy provider, Salzburg AG, decided to build the new Rott hydropower station as well as a new dam and fish ladder down-stream of the Saalach plant. The new Rott hydropower station will feature two new VA TECH HYDRO PIT turbines with spur gear and a runner diameter of 2,350 mm as well as two high-speed synchronous generators by ELIN EBG.
The energy output of the new Rott hydropower station will be 47% more than that of the existing Saalach hydropower station, an increase in annual energy from 19,000 MWh to 28,000 MWh, primarily due to the higher efficiency of the new equipment. The Rott project will positively stimulate the environment and provide a boost to the local economy. Beginning in autumn 2004, the Rott power station will supply more than 7,000 households with green water energy.
