The Zufikon power plant is a run-of-river power plant on the Reuss in Zufikon and Bremgarten in the canton of Aargau . It is considered the first three-phase - hydroelectric power station in Europe and is one of the AEW Energie AG.

history

old power station Zufikon, machine house from 1894

The Zurich turbine manufacturer Escher-Wyss built the Zufikon power station on the Reuss in 1893/94 to supply energy to its factory in Zurich. The Francis turbine from 1928 was in operation until 1974. In 1974 the old power plant was demolished and replaced by a new one with a higher output.

The Reuss Valley Act, which defined the extent of the Reuss valley rehabilitation, was adopted by the people in 1969. The renovation measures covered an area of ​​around 45 square kilometers, including the construction of the new Bremgarten-Zufikon power plant. The Bremgarten-Zufikon power plant, which went into operation in 1975, is a model for the balance of interests between landscape and nature conservation ( Flachsee ) on the one hand and flood protection and water use on the other.

The new power plant has dammed the Flachsee since 1975. The Reuss will be dammed 11 meters above its mean water level to a water level of 380  m . The backwater of the water extends over the Flachsee to the Werd bridge (9 kilometers upstream).

The power plant is fully integrated into the course of the river, with modern gate and turbine types enabling it to be architecturally integrated into the surroundings. In the nacelle there are two bulb turbine groups with two three-phase synchronous generators and two transformers connected in block. The fully automatic operation of the power plant is controlled by switching it on or off depending on the water supply.

AEW Energie AG's 110kV / 16kV substation is located next to the power plant. The energy generated here is fed directly into the 16 kV network of AEW Energie AG.

In March 2016, the impeller was replaced with four new impeller blades for machine group 2.

Today's production

The power plant can supply a medium-sized Aargau town with around 23,500 households with green electricity. It has been certified with the “Naturemade basic” quality label.

The bulb turbine system with an output of 20 MW (megawatts) generates around 106  GWh of electrical energy annually . The usable amount of water is 200 m³ / s (2 × 100 m³ / s) with an average gradient of 11.2 meters. The discharge capacity is 900 m³ / s.

Sightseeing

Visits to the Bremgarten-Zufikon river power plant are only possible in groups. A tour with a lecture takes about two hours. There is an information service for schools.
