Kraftwerk Bruggmühle

Kraftwerk Bruggmühle in Bremgarten is a historic hydroelectric plant on the Reuss river in the Swiss canton of Aargau. It sits on a river island at Wohlerstrasse 2, next to the old town, and houses a small museum of power-generation technology.

What is this place?

The site's story begins long before electricity. A mill here is documented as early as 1281 and probably arose together with the bridge over the Reuss. It is regarded as one of the oldest river mills in Switzerland. The Habsburgs first owned it, the town took it over before 1361, and it passed into private hands in 1835.

That same year a spinning mill replaced the grinding mill. Flowing water drove a sawmill and textile machinery directly. From 1892 the river's energy was used to generate electricity, and in 1895 Kaspar Hausherr founded the company "AG Elektrizitätswerk zur Bruggmühle". It supplied the town and powered the Bremgarten–Dietikon tramway.

How did the plant develop?

Expansion came in stages from 1921. In 1924 a turbine by Theodor Bell & Co. of Kriens was installed on the right side, and it is still there. In 1927 the cantonal utility AEW took over. The main building as it looks today dates from 1938–39 and follows the regional Heimatstil.

The cantonal heritage inventory lists the turbines and generator from 1906 (inventory no. BRG052). The plant has been under cantonal protection since 1995 and is rated as regionally significant.

Can you visit?

Since 2005 the plant has held the Museum Reusskraftwerk Bremgarten, which shows older machinery in working order. Admission is free, but visits are by arrangement and for groups only. Spontaneous drop-ins are not possible, so agree a date in advance. You can view the building and the island from outside at any time.

Not to be confused with

A larger run-of-river plant, Bremgarten-Zufikon, operates nearby. It opened in 1975 and has a capacity of 20 MW. It is a separate, modern facility, whereas Bruggmühle is the older heritage plant in the town itself. The operator says both plants carry the "naturemade basic" label for renewable energy.

Who is it for?

Anyone interested in industrial heritage, engineering history or architecture. It pairs well with a walk through Bremgarten's old town, which sits inside a bend of the Reuss, and along the river. For a group tour of the plant, plan about an hour.
