We have been supplying 1. FC Union Berlin with sustainable energy since 2012 – and now we’re stepping it up! As the official energy supplier, we not only provide the club with green electricity and green gas, but also focus on social impact: with “Eiserner Strom,” we are working with the “UNION VEREINT. Schulter an Schulter.” foundation to support important social projects and strengthen club life beyond the sport itself. Our customers benefit twice over: every new contract signed unlocks exclusive ticket opportunities for both the women’s and men’s team matches. In addition, we offer fair tariffs that are guaranteed to be below the basic supply rate. We also support regional sports: for every 500th new customer, a donation is made to a partner club in Union territory.
