This hydro power plant at Sandfangweg was switched on at the end of 2008 and produces on average 300,000 kWh per year. Due to its innovative construction resembling a snail the turbines require only a slight downhill gradient. On the Dreisam river this equates to a drop of about 3 meters.
To be viewed from the outside, guided tours by appointment.
