The Aare power plant is a run-of-river power plant in Beznau , a district of the municipality of Döttingen in the Swiss canton of Aargau .
history
The power plant was planned and financed by Motor AG for applied electricity . The plant was built between 1898 and 1902. The Francis turbines were manufactured by Bell machine works in Kriens. One of the turbines was exhibited at the Paris World Exhibition in 1900 .
After the power plant on the Löntsch in the canton of Glarus was completed, it was combined with the Aare power plant to form an electricity network , which was operated by the Beznau-Löntsch power plant , a subsidiary of Motor AG. The company was sold to the cantons in north-eastern Switzerland in 1914 and renamed Nordostschweizerische Kraftwerke AG , which is now called Axpo AG .
technology
The power plant uses the gradient of the Aare over a length of 7.4 km. It stands at the end of an artificial headwater canal . The Beznau nuclear power plant is located on the island between the upper water canal and the Aare .
Each of the eleven installed turbines has an output of 1.77 MW with a water volume of 418 m³ / s, which results in a total output of 19.5 MW. Approximately 147 million kilowatt hours of electricity are produced annually.
Since 2001, in addition to the main power plant at the end of the upstream canal, the water flowing back into the Aare via the weir at the beginning of the canal has been used by a turbine built into the weir, which has an output of 6 MW and produces 42 million kilowatt hours of electricity annually.
