The Kappelerhof power plant is a run-of-river power plant on the Limmat in Baden in the canton of Aargau . It is the oldest larger river power plant in the canton and belongs to the Regionalwerke AG Baden (formerly Elektrizitätsgesellschaft Baden AG ).
history
At the world exhibition in Paris in 1889 , the representatives of the Elektrogesellschaft Baden (Karl and Theodor Pfister) planned with the founders of Brown, Boveri & Cie. , Charles Eugene Lancelot Brown and Walter Boveri to build a machine factory and a hydroelectric power station in Baden.
The Kappelerhof hydropower plant was built from 1891 to 1892. The BBC supplied the first group of machines in 1892 and three more from 1893 to 1895. After commissioning, the power plant had an output of 1000 kW. The Kappelerhof was rebuilt from 1974 to 1976 and the old power plant was shut down in favor of a new underground system. One of the four machine groups was retained and integrated into a museum. Despite the reduction to a single large Kaplan turbine , electricity production could be doubled to 20 GWh.
In the years 2003 to 2007 a total renovation took place, in which the original canal power plant became a river power plant, which was located at the end of the newly dammed Kappi lake . It was a second machine group and a three-span weir created and made ecological enhancement measures (redesign of the islands and shore areas, construction of canoe trails and boat ferrying bodies, construction of a fish ladder three entrances).
Since 2012, the waste heat from the machine groups has been used to heat the company buildings in the Kappelerhof using heat pump technology and storage tanks. With the CO 2 -neutral waste heat utilization, around 9,000 liters of heating oil can be saved annually.
Today's production
The Kappelerhof has had two machine groups since 2007. With an average annual electricity production of 35 GWh, it can supply around 8,200 households with renewable energy. The maximum water use is 140 m³ / s with a gross head of 6 m.
Electric museum
The electronics museum shows how historical devices and equipment from power plants, industry and private households used to generate, transport and consume electricity. The showpieces of the collection are the complete historical machine group, the drained chamber for the turbine installed in 1918, the wooden cogwheel and the generator from 1925. The various types of energy production are illustrated in the video and demo room. A visit to the electrical museum in the power plant is free. Advance booking is required for visits to the museum outside of the opening times and for tours of the Kappelerhof power plant.
