The Brugg power plant was a former run-of-river power plant in the city of Brugg in the canton of Aargau . It was located on the right bank of the Aare at the entrance of the river into the Aare gorge next to the Brunnenmühlesteg, about 300 meters above the old town of Brugg. The machine house is a sight on the fifth stage of the Limmat – Wasserschloss industrial culture trail .
history
After the Limmat power station Kappelerhof of the city of Baden , the Brugger power station was the second municipal power station in the canton of Aargau. Both plants were built in 1892. The Brugg power plant was built by the municipal electricity company, today's IBB Energie AG in Brugg. The preparations for the construction of the Aare power plant led to the granting of the operating license to the city of Brugg by the government council of the canton of Aargau on August 14, 1890 . Interested electricity users in the municipality could now register for subscriptions to light and power electricity.
Construction of the plant began in 1891 according to plans by engineer Schmid-Läuchle from Aarau . About 200 meters above the then independent village of Altenburg, which was incorporated into Brugg ten years later, at what is now the Brugg outdoor pool, the right bank upper water canal ▼ began , which carried the water in a brick canal bed around the rocky promontory of Altenburg, along the slope of the elevated terrace and under the Brugg railway bridge -Umiken led through to the power station. The water was returned 1150 m below the water intake at the confluence of the Süssbach and the Aare, where the power plant's machine house is located.
In the machine house there were initially two Jonval turbines from Maschinenfabrik Rieter AG in Winterthur , which together produced 500 hp .
In 1895, the Schinznach thermal baths joined the distribution network of the Brugg power plant, which initially primarily supplied electricity for lighting. In 1898, the power station's distribution network had nine major customers. A 300 HP steam engine from Sulzer was installed to increase performance and supplement it in the event of water scarcity . From 1901 to 1911 the supply area was expanded to include the municipalities of Altenburg, Umiken , Lauffohr and Birrenlauf .
In the years 1901 and 1902 a major renovation of the plant was due. A third turbine was installed and the 125 kW dynamo from Siemens , which generated direct current with a voltage of 500 V, was put up for sale in 1901.
The city of Brugg planned to merge with the Zufikon power plant , which was later transferred to the Aargau Electricity Works. In 1911 the city of Brugg built a municipal gas works near the Brugg train station below the old town .
Between 1915 and 1921 the communities of Scherz , Habsburg , Königsfelden and Hausen were also connected to the power grid. A bed sill created in 1918 and a simple weir led more water to the headwater canal. In 1928 only one Jonval turbine was installed in the power station, the rest had already been replaced by Francis turbines . After replacing the last Jonval turbine, the plant had an output of 910 hp.
On April 14, 1940, a flood destroyed the weir in the Aare. In 1943 and 1944, the roof weir ▼ , which was still in existence in the 2020s , was built into the Aare.
In 1947 a propeller turbine , a Kaplan turbine and a Francis turbine were installed in the power station , which together could produce an output of 1500 hp .
At the end of 1952, the Brugg power plant was shut down because the new Wildegg-Brugg NOK power plant began operation a few kilometers above the town of Brugg in the floodplain landscape on the Aare . The license for this plant was granted in 1917. The former headwater canal was backfilled except for a short stretch below Altenburg and serves as a section of the waterfront between the old town of Brugg and Altenburg.
