The Oberstufe Lutz power plant is a run-of-river power plant operated by illwerke vkw AG in the municipality of Ludesch in Vorarlberg . It was erected in the years 1965 to 1967 by the Vorarlberg power plants in the lower reaches of the Lutz after the approval of the Federal Ministry of Agriculture and Forestry on December 23, 1964 . The power plant uses the 130 m difference in altitude to the Raggal reservoir . It has an installed capacity of 19.3 MW and produces more than 73 GWh of electrical energy annually .
From memory Raggal the water passes over a 4.5km long headrace tunnel for water tower and from there vertically to the machine cavern , some 100 meters inside the mountain is located. There the water is in a vertical Francis turbine processed and flows into the reservoir Gstins , located on the municipal boundary between Thüringerberg is and Ludesch. From there, a 4.6 km long pressure pipeline leads over a gradient of 72 m to the lower stage Lutz power plant .
