Own energy

from hydropower and photovoltaics

Due to the conversion of our fleet to e-cars, the demand for energy is constantly increasing. In order to meet this demand, we have invested in the construction and expansion of our photovoltaic systems over the last 3 years. Since the end of 2021, we can also count a hydroelectric power plant to our group. Thus, nothing stands in the way of refueling sustainably generated energy for the electric cars.

The diagram shows the history of the SENN Gruppe. In 2001, the company was founded by Franz Senn sen. in Kufstein. Since then, various companies have been added to the group over the years. In 2023, the highlight will be the move into the new warehouse and production hall in Erl, Mühlgraben 43e. This will create the space for further growth.
