Sustainable Electricity from Our Energy Community

At Kostmann, we don’t just focus on quality in construction—we’re also taking a forward-thinking approach to energy. Our energy cooperative, which includes two hydroelectric power plants, produces 5 million kWh of electricity annually. Together with our 20 photovoltaic systems, we cover the majority of our energy needs ourselves and are thus making an active contribution to the energy transition.

Our dedicated team of electricians ensures that our facilities are supplied with sustainable electricity from the region. Not only do they install the solar power systems themselves, but they also professionally maintain and service our hydroelectric power plants.
