The lower stage Gampadels power plant is a hydropower plant operated by illwerke vkw in Vorarlberg ( Austria ). The power plant (machine house, 681 m above sea level ) itself is located on Werkweg on the southeastern edge of Tschagguns .
History and use
As early as July 1918, the Vorarlberg State Committee set up an expert commission. a. rated the project for a power plant on the Gampadelsbach (“Lederbachquelle”) previously worked out by the office of Ing. Riehl in Innsbruck as favorable.
The construction of the Gampadelswerk (lower stage) was decided by the Vorarlberg state government on December 21, 1921. The plant was planned to deliver four million kWh of electrical energy per year, with a net gradient of 380 meters and a flow rate of 500 l / s. The Bitschweil day storage facility was built for 18,000 m³. The individual electrical power plants in Vorarlberg were to be interconnected to form a network by means of new long-distance lines. The estimated cost of the power plant was 60 million Austrian crowns . However, due to the strong inflation, this budget could not be met. On April 30, 1922, 92 million crowns had already been built. As a result, the state of Vorarlberg wanted to finance the plant through a mixed-economy company. It was decided on March 2, 1923 an energy tax for the period from May 1, 1923 to June 30, 1924 and this energy tax had to be extended until the end of 1926 due to increased construction costs. Another workers' strike from July 28 to October 22, 1924 paralyzed the progress of work, as did the problems with the delivery of the machines. The generators arrived five months later than planned. The required Pelton turbines were built in 1924 by the Dornbirn company Rüsch-Ganahl. Due to a three-month strike and the unilateral solution of the collective agreement by the company and the dismissal of the 89-strong workforce, there were delays in delivery and the turbine blades then showed hairline cracks and had to be replaced. On April 3, 1925, the Gampadelswerk went online.
The Gampadels lower level power plant was originally intended as a reserve power plant for energy supplies in winter.
In 1989, the second stage of the two-stage Gampadels power plant group in the municipality of Tschagguns in the Montafon , the Gampadels upper stage power plant , was built. Both power plants use the hydropower potential of the Gampadelsbach up to the point where it flows into the Ill .
On April 11, 2012, the VKW applied for the reassignment of the right to use water for the lower level of the Gampadels power plant and a general renovation was also requested.

Bitschweil storage facility
The Bitschweil reservoir (also the Gampadel reservoir) is around 170 m long and at its widest point measures around 45 m. It now holds around 32,000 m 3 and is 1076.5 m above sea level. The water reaches the lower-level powerhouse via a pressure pipe from the Gampadels upper level power station, where it is processed by another three sets of machines and from there it reaches the Ill. The energy is fed into the network via the Tschagguns substation.
- Length of the pressure line: approx. 655 m
- Laying: mostly in the ground
