Where does our electricity come from?
100% of our electricity comes from hydropower.
For the amount of electricity supplied to our customers, corresponding certificates of origin from hydroelectric power plants are used. These certificates also serve as the basis for regular certification by TÜV NORD.
On this page, we provide transparent information about where our energy comes from and the composition of our electricity supply.
What does "100% hydropower" mean?
Electricity from various sources is transmitted together through the public power grid. That is why the electricity coming out of your outlet does not come exclusively from a specific power plant or electricity provider.
However, for our customers' electricity consumption, the corresponding amount of hydroelectric power is verified.
