The Alberschwende power plant is a run-of-river power plant operated by illwerke vkw of the diversion power plant type and is located on the northeastern edge of the Alberschwende municipality in the Bregenzerwald on the orographic left side of the Bregenz Ache . It went into operation in 1992; it has an installed capacity of 30 MW and generates more than 96.4 GWh of electrical energy annually .
The diversion power plant uses the gradient from the Ach compensation basin at the Andelsbuch power plant to generate energy , from where a pressure tunnel feeds the water to the Alberschwende power plant downstream. Two sets of machines, each with a Francis turbine and a generator, generate the electrical energy there, which is fed directly to the nearby Vorderwald substation. The main control center in Bregenz monitors and controls operations remotely.
The power plant Alberschwende is its water together with the nearby power plant Langenegg via the below-scale parallel to Bregenzer Ache page memory Bozenau controlled in the Bregenzer Ache back and thus avoids surge formations.
The E-Werk Egg , located between Andelsbuch and Alberschwende , which the municipality of Egg built in 1907–1908 and sold to Vorarlberger Kraftwerke in 1974 , was shut down in the course of the completion of the Alberschwende power plant because the processed water from the Andelsbuch power plant has not been used since then Bregenzer Ache is fed when the Alberschwende power plant is in operation.
